run. >> send everybody you possibly can. officer is down. >> residents are being told to stay inside. schools are on lockdown and police units in the air and the ground and using canine teams, there are reports of officer stripped of his gun and mace. the three suspects are considered armed and dangerous. the fbi, u.s. marshals and regional s.w.a.t. teams are on the hunt. this is ongoing from about most of the morning there. joining me now on the phone is phil rogers, a reporter with affiliate wmaq. thank you for making the time. >> thank you, luke. >> around 8:15 central time, the police officer apparently came across three suspects that were at a building that had to do with cement company. said that he was investigating suspicious behavior. then radioed for backup at some point. he was no longer in contact with central command.

it is at that point that another officer came upon him, found him murdered and that the suspects then took his gun and mace and had been on the run since this morning. give us a little layout of this area north of illinois. this is a place where people i understand have second homes, it is heavily wooded, rural. fox lake. there are a lot of lakes up there. there's rail access, route 12 from the metropolis of chicago. when's law enforcement looking at in this hour in terms of trying to find the individuals? >> unfortunately, they're looking at a lot of places where people can hide but don't mistake this for being out in the middle of the country. fox lake is a commuter bedroom community. it's about 59 miles northwest of chicago. ten miles south of the wisconsin border. adjoining an area called the chain of lakes, a big resort area where folks from chicago like to go to do boating and fishing on the weekend. it is a very familiar area to a

lot of people and a lot of tiny communities kind of blur together out there with the woods intermingled between them. so police have the challenge out there right now of knowing that there are a lot of forests out there where people could be concealed. only thing we know for certain how this began is the officer radioed in and said that he was in pursuit of the individuals in question and that was the last transmission reportedly that they had from him. after that, you know, you heard the transmission that there was an officer down. now, we do know that they have said the all-call messages that they know that the suspects have his weapon, also his mace. there was no mention of his police radio. whether that was found at the scene or not. of course, that can be a tremendous problem, luke, if they were armed with the radio and aware of the movements of the officers in the area but

there'm an overwhelming police presence because there's a distinct advantage here. there are so many communities out there who have mutual aid agreements with fox lake and with the lake county sheriff's office, all of those have been pouring in to provide assistance. there's no shortage of manpower. the only question is how far the individuals got before those perimeters were established. >> correct. that's what we're looking at right now as we see the police presence you mentioned. helicopters, the individual officers that are donning military fatigues, heavily armed, searching this area. i presume boats are used right now. phil rogers of wmaq, thank you. >> thank you. >> i want to bring in lenny depaul, a former u.s. marshal and sean. lenny, i want to start with you. in a situation like this, knowing that terrain, you're on a lake.

there was a commuter rail that was going in the morning. we do not know if they had access to a car. you're ten miles from the wisconsin border. what do you do in terms of setting up a perimeter to try to find these three suspects? >> good afternoon, luke. great questions. questions i'm sure law enforcement have answers to. it's a math equation. the backup arrived this morning. the three individuals, together? did they get into a vehicle? did they hop on the train? these are questions that law enforcement needs to have answers to. i'm sure a perimeter was set up quickly. an intense manhunt pursued and casting a very wide net. they have thousands of law enforcement officers out there and all necessary assets have been deployed from aviation to bloodhounds, to hostage negotiators is there on the scene and hoping they have somebody identified or they're working with witnesses or cooperators or whatever.

we don't know why the officer was alerted to the three individuals, was it a car stop? is there a vehicle in play? i'm hoping these questions have been answered. why he d he stumble on to the three? was it a drug spot? the location, the officers that work that area, they're going to know the answers. they may even know the three individuals. they may be from out of town. there's a lot of maybes and what ifs going on and hitting on all cylinders a ten necessary m manpower and equipment to do their job. >> sean, not much is known about the suspect aside from two whites and one black we believe. in an area like this, where you have so many of these vacation homes, part of -- this is a bedroom community and a lot of vacation homes there. i was going through and doing some research and saw a lot of boats there. of course, that put the light bulb about tsarnaev.

this is difficult terrain for law enforcement to search through in such a quick manner because you have the marshland, you are the forest, you have the water itself, you have the railways, you have perhaps homes unoccupied right now because it's the middle of the work week. what's the sort of plan of attack to go through the areas and how do you attack that from the federal to the state level? >> that's right, luke. the topography is disparate. you have potentially three armed suspects near an area of vacant homes, you have got forest area. you have got major buildings in the area. very, very difficult to go building by building in ear a yeah like this. i think the prior reporter mentioned that there are a lot of surging law enforcement resources into this area. there are surrounding counties and villages, the federal agencies, both the atf, the marshals, the fbi, all of them bringing their resources and

their expertise to bear. that really is one of the key things you want to focus on. one of the other things i think you want to focus on is the use of social media and the media writ large. the citizens in the community are going to be the ones who are going to alert law enforcement very likely. somebody's going to see somebody they don't know, somebody unusual. they're going to recognize some anomalous behavior and make a phone call in. the use of technology to get the word out, particularly of the opportunity of people getting into wisconsin and they have already gone beyond the perimeter that was established early on. it is really the use of the community and the scitizens to law enforcement. >> i want to reset this for our viewers. around 8:15 central time, a police officer pursuing three suspects in a building northwest of illinois in fox lake. that officer called for backup.

when backup arrived, they found him deceased. it's clear that these suspects, two white, one black, have been on the run since this morning. they are considered armed and dangerous. they took the officer's pistol and mace. it's unclear if they were armed prior to what they took from the officer and unclear if they have the officer's radio which, in fact, they did would be a huge coup knowing the movements of the officers. lenny, i want to go to you. when's the timing here in terms of sort of setting up the perimeter and trying to clear everything that the perimeter is around? does it go to the night fall? through the night? what do we look at in that trying to figure out how far they may have gotten? >> we -- absolutely, luke. this is certainly going to go around the clock until they're in custody. i mean, the terrain is very rough, tough on law enforcement. also tough on these three suspects. i mean, they got to get through the rough terrain, try to run,

hide, escape. not if they're in a vehicle, on foot. you know, they're human instincts turn into animal instincts. desperate people do desperate things. they're armed with the officer's handgun. not sure if he was shot or how he was killed. these are questions that have i'm sure law enforcement has answers to but, you know, it's a full-court press until these three are in custody and i'm hoping they they have cooperators, maybe witnesses or somebody stepped up and knew the three individuals and a matter of time before the public is made aware of who they are and their identified to law enforcement and then at that point it will certainly be a matter of time before they're taken into custody. >> we do not know of any eyewitnesses or anybody saw anything suspicious with the exception of the officer. shawn, this area is a bedroom community. it is also a place where a lot of chicago residents keep a second home as we mentioned

before but that route 12 road, that goes all the way to chicago. you also have the train that was running this morning. now, we should say that train service is suspended in that area, specifically to not help these suspects, able to try to jump on a train but from the law enforcement perspective, how do you set up a perimeter with a thoroughfare going to a major large city like chicago and easy to blend in and you have a train that runs through and goes into chicago. as well as a lake that perhaps able to move quickly enough, not unheard of to jump on a boat? >> yeah. the circumstances are quite arduous. you know, we are not clear on how much time officers had to set up a perimeter and how much of a lead time these murderers may have gotten. they certainly would have been checking trains and they have got the thoroughfares covered but beyond that, assuming they have gotten beyond the perimeter, they'll be searching the house to house that we talked about earlier.

police officers going street by street, using canines and using air surveillance but beyond the perimeter, it's about getting the message out to others, surrounding states, surrounding communities so people are aware of what's occurred and to be on the lookout. at this point, there's not a lot to go on. we don't have a good physical description. we don't have identification of a particular vehicle so it really is looking for anomalous behavior and that's a rough thing to go on for law enforcement or the community. the citizens. not a lot of information at this point, luke. i think that those officers that are on that interior perimeter house to house and trying to put as much resources into the space to potentially flush those people out is critical but there's also that possibility of innocent civilians, they take residence into a house, a family in there. you have a hostage situation. arduous circumstances. >> it is. we should mention the schools in that area are on lockdown and so

arduous with the conditions. this is a very -- it's very different diverse area with topography. you have the lake. you have the railroad tracks. the highway all the way to chicago. not easy terrain. thank you so much. stay with us. we'll be right back with the latest on this massive manhunt under way in illinois. here are some new pictures on twitter of the manhunt taken from a viewer's balcony. staying in rhythm... it's how i try to live... how i stay active. so i need nutrition... that won't weigh me down. for the nutrition you want without the calories you don't... introducing boost 100 calories. each delicious snack size drink gives you... 25 vitamins and minerals and 10 grams of protein. so it's big in nutrition and small in calories. i'm not about to swim in the slow lane. stay strong. stay active with boost®.

i'm sorta marge... you're not marge? we both drive a stick, we both like saving money on car insurance, and we both feel integrity, such as, that of healthcare in the america of the us and therefore. yes. thank you. no. no. please, stop! sorta you, isn't you. start with a quote from esurance and get a set of discounts personalized to you, not someone sorta like you. esurance. backed by allstate. click or call. before i had the shooting, these feet grew up in a family diabetic of boys... married my high school sweetheart... and pursued a degree in education. but i couldn't bear my diabetic nerve pain any longer. so i talked to my doctor and she prescribed lyrica. nerve damage from diabetes causes diabetic nerve pain. lyrica is fda-approved to treat this pain. lyrica may cause serious allergic reactions or suicidal thoughts or actions.

tell your doctor right away if you have these, new, or worsening depression, or unusual changes in mood or behavior. or swelling, trouble breathing, rash, hives, blisters, muscle pain with fever, tired feeling, or blurry vision. common side effects are dizziness, sleepiness, weight gain and swelling of hands, legs and feet. don't drink alcohol while taking lyrica. don't drive or use machinery until you know how lyrica affects you. those who have had a drug or alcohol problem may be more likely to misuse lyrica. now i have less diabetic nerve pain. and i love helping first graders put their best foot forward. ask your doctor about lyrica. and i am a certified arborist for pg&e.ughes i oversee the patrolling of trees near power lines and roots near pipes and underground infrastructure. at pg&e wherever we work, we work hard to protect the environment. getting the job done safely so we can keep the lights on for everybody. because i live here i have a deeper connection to the community. and i want to see the community grow and thrive. every year we work with cities and schools to plant trees in our communities. the environment is there for my kids and future generations. together, we're building a better california.

there are three suspects at large at this time. again, described two male whites, one male black. >> that's detective christopher cavelli. no confirmed sightings of the suspects wanted in the death of an illinois police officer. with us now on the phone is dan maran. thanks for making the time for us. >> thank you for having me. >> dan, talk to us a little bit about where this is happening, this building, specifically, that the officer came up on these individuals who were engaging in suspicious behavior. what do we know about this area of town and what would lead a police officer to go over there, around 8:15 in the morning? >> well, the main drag through town, a highway through most of lake county as you enter fox lake. from 50 to 40 to 35 so in that area that's the beginning of the

business district. and it's 35-mile-a-hour speed limit and getting up on franchise road and another half mile, mcdonald's and everything, so that's kind of a business district area. there is where you see most of the searching today. has been in wetlands areas kind of. it's either side of the downtown area. >> and fox lake, what es it like in terms of the crime rate there? seems to be a bedroom community, people have second homes. wh what's -- i presume this is unheard of up there. >> yeah. it's, you know, it's really called a far northwest suburb of chicago. you have the chain of lakes, very big rekricreational area. going to be busy for labor day. it was resorts, you know, people coming up here for the summer and shut down for the winter. other than ice fishers.

we were kind of putting our heads together with some of the reporters here who have been around for a while. here in lake county, the only example that we could think of of police officers being shot was in i think in 1991. all the way back then. and it was oddly enough also along route 12 but a good 10, 15 miles south of here in the lake zurich area. it's quiet. >> fox lake is fairly quiet, safe place. very much out of the ordinary. give me a sense of what it is like on the ground there. i presume streets are blocked off and schools on lockdown. there was a no flight zone around the area for sometime. this is a massive manhunt with bloodhounds, helicopters. we see officers in military fatigues. it is not a business as noshlal day for the residents by any means. >> no. you know, as it stands right now, it is very quiet.

a lot of helicopters have landed but i was told that that doesn't mean anything. they're still looking. that was just a little bit ago. haven't heard anything beyond that. the high school, the main high school, grant high school, i'm at the fox lake police department. it's about half a mile from here and i think they're supposed to get out of school in half hour, 45 moneys. we have not heard anything from them. i can't imagine they let them out with this actively going on. every five minutes a squad car goes by with the lights on. so definitely a developing situation still. as i'm speaking to you, here comes a helicopter. >> yeah. it's intense. dan, just before i let you go, what are the typical crimes that you would cover in a place like fox lake? >> well, you know, i'm not regular police reporter but, you know, i think if you spoke with frank our police reporter he

would tell you arrests on chain of lakes for intoxicated boating. that's the type of thing that you will hear about most. you know? other than the usual disorderlies, things like that. you know? if you had to draw, participate a big brush, that's probably what you're used to hearing about. maybe an incident on the chain of lakes. nothing like this. >> nothing like this, indeed. dan moran, thank you so much for your time. we appreciate it. all right. joining me now is former fbi profiler clint van zandt. clint, we know that you have the fbi involved in this. you have the atf. you obviously have the local police force there in that county, as well as from surrounding counties. talk a little to me about the coordination efforts for something like this. there's a lot of manpower on the ground trying to get the three suspects. but they have to work in unison. how's that done? >> well, they do. this is always interesting,

luke, when you bring the city, state, county and federal agencies together. time is of the essence. you talked about school being released. pupils going home. parents coming home from work and chicago and the nearby communities. when you have all of these law enforcement, all of these tactical resources that come together, the lake county authorities are in charge. basically, the department from who the officer was employed by, that's their case. it's their homicide. and yet, the lake county authorities up there will come together and, yet, the marshal service and the fbi has a lot more experience in these massive manhunts than many times local agencies do. so i mean, i have done this before. you have to come in. you have got to say, these are our resources. fbi, marshal service, we're here to help you. you tell us what we can do for you and if you'd like us to help

set up the command post, if you would like us to help computerize the searches, we can do that, too. most local departments say, you know what? this is our case. this is our officer. but we'll take all the help we can get and then they put all of their resources together. just like luke, you know, when we covered the two escaped prisoners from the prison, you had every local, state, county, state agency came together. there was head butting went on in a situation like that but in this situation right now with an officer slain, everybody's there to help. nobody's looking for headlines. they're looking for the three guys responsible for killing this police officer. >> and, clint, you heard the local reporter who was on with us just a moment ago. dan moran said that this type of crime is unheard of in this area of fox lake. this is a place that's often a recreational community, a resort community.

a far bedroom community from chicago. just from hearing that, that this is very much out of the norm in this area, you have three suspects, two white, one black, what can we ascertain perhaps that was a motive behind this? they were seen around a building acting suspiciously and caused the officer to move forward. this is very much out of the ordinary for the area. what can we ascertain from the suspects and what might the motives be or react to killing a police officer? >> well, that's part of what this fugitive task force is looking at right now. what brought this about? as you suggest, luke, this took place in the morning. it was around 8:00. daylight was already upon us in that area. so the question is, would they have been committing some type of burglary or planning a robbery or a drug deal that was going on behind a building and somebody saw three suspicious individuals?

called the police and said, hey, you know, you ought to come take a look. we don't know the sum total of that right now. and we don't know who these individuals are. the police may. the police may have, for example, i know they have already been looking at surveillance cameras in the area, luke, on businesses. trying to come up with pictures, cars, license plates. anything like that that will help them identify these three suspects. they may already have an idea who one or the other might be and realize, luke, this officer killed just a few hours ago. this is number 24 of police officers who have been slain by gun fire already. we have had 83 police officers die this year. 24 have been shot down in the line of duty. so, each time you and i see these and you're required to report this, there's hand wringing going on and each time wander what was the motive? is there anything planned or was

this just a random incident, of violence and what otherwise is a very quiet bedroom and resort community. >> yeah. still very much trying to figure out the motive behind all of this. clint van zandt, thank you so much. we appreciate it. we'll be back with the latest on this massive manhunt under way in illinois after a short break. well, we have 30 years of customer records. our cloud can keep them safe and accessible anywhere. my drivers don't have time to fill out forms. tablets. keep it all digital. we're looking to double our deliveries. our fleet apps will find the fastest route. oh, and your boysenberry apple scones smell about done. ahh, you're good. i like to bake. add new business services with at&t and get up to $500 in total savings. sup jj? working hard? here at the td ameritrade trader group, they work all the time. working 24/7 on mobile trader, rated #1 trading app in the app store.

it lets you trade stocks, options, futures... even advanced orders. and it offers more charts than a lot of the other competitors do in desktop. you work so late. i guess you don't see your family very much? i see them all the time. did you finish your derivative pricing model, honey? for all the confidence you need. td ameritrade. you got this. it's tough, but i've managed. crohn's disease. but managing my symptoms was all i was doing. so when i finally told my doctor, he said humira is for adults like me who have tried other medications but still experience the symptoms of moderate to severe crohn's disease. and that in clinical studies, the majority of patients on humira saw significant symptom relief. and many achieved remission. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb.

tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. if you're still just managing your symptoms, ask your gastroenterologist about humira. with humira, remission is possible.

lack back. we're continuing to follow breaking news. a massive manhunt under way in illinois after a police officer was shot and killed according to law enforcement sources. wmaq reporter christian farr is on the scene. what do we know? >> several police agencies are out here. we see the illinois state police and other agencies in the lake county area, they're searching possibly for three people. we know definitely they're searching for two people, possibly a male white, a male black and not sure the circumstances that led to the

shooting but an officer was shot. law enforcement sources are telling us that he has died. police are using helicopters and we saw a helicopter out here earlier looking around a lot of police officers. along this road searching some of the communities, trying to find these suspects. they're trying to contain the area and some schools including grant community high school have been locked down and this happened shortly after 8:00 this morning. in the 100 block of honing. we don't have specific details of whan led to the shooting but again an officer was shot. law enforcement sources telling us the officer has died. we are told they're searching for at least two suspects at this point. there possibly might be a third. they believe the suspects to be armed and very dangerous. the area where this shooting happened is roped off. there's a heavy police presence going on right now. and we'll continue to follow the story and bring you late-breaking details once we have them. >> thank you so much, wmaq's

christian farr. i want to bring back lenny depaul, former u.s. marshal and on the phone msnbc law enforcement analyst jim cavanaugh, a former atf special agent. lenny, starting with you, we're coming now within an hour when school would ordinarily be let out in that area, schools have been on the lockdown, the entire town is on lockdown. i presume for the benefit of this manhunt and this search. i'm sorry. i want to go to jim with this question. i presume, jim, for the benefit of this search that you would from a law enforcement perspective went to keep the schools locked down and would want to keep traffic at a minimum. >> right. exactly. luke, let's lock down the schools with the children and the educators in there and then usually bring deputies or police officer there is to make sure they can safely get them out and on buses and might have to escort people or the parents come pick them up and once they make sure that the killers have not gotten into a school or do

something to children, it's -- they'll be able to do that i think before night falls and pretty routine. we don't know if the killers busted the area right off because they didn't go there on foot and it sounds to me like they were interrupted in the process of committing a crime, could have been a burglary, a drug deal and trying to steal something, they might have been plotting something and that's when the officer came upon them. they fled on foot. and of course, they ambushed him in the woods apparently. the way they do that is they could have had firearms or even one of them hides behind a tree or a bush and when the officer comes by, they jump on him. >> that's why they shut it off. >> yeah. jim, stay with me here. from what we understand about the facility where these suspects were located, is that it was owned by a concrete

contracting giant in illinois. i believe from the local chicago affiliate, it was prairie materials if i'm correct. we are unclear if this was a building where people worked at every single day. from the looks of it, doesn't look like the most vibrant places with overgrown weeds there, large parking area and whatnot and we do not know at this time. i want to go back, though, to fox lake and the area because we are unclear if the suspects had access to a car. we obviously know that commuter trains were working at that time, a time of people going into work from a bedroom community as well as you have all these lakes and these boat that is are around there. so in this situation, we have to keep coming back to this. it's very difficult to know how far that perimeter should be set up with so many options available to these three suspects immediately after they committed this murder. >> right. what the officer reacted to

initially, luke, the three fled on foot because that's the last information that they have from the officer who was deceased. so naturally, they flood the area. they try to set up a perimeter and might have fled on foot. if they had got in a vehicle, they could be long gone before that perimeter is tight enough to be able to find them. these places, they could have known about equipment stored there. construction equipment. generators and that stuff is always a target of burglars and thieves. if they thought there was no one there and steal something there and might have been there to do that. some scenario like that. and officer comes upon them. they run. because they're in the middle of committing a crime. sounds like a crime crew. doesn't sound like coming to attack and kill the officer like the fellow in texas killed the deputy. this feels like a crime were broken up and either fugitives or escapees and ran away.

sounds like a crime crew more likely. trying to get something, burglary. might have entered a car, pickup truck around the building in the back or the corner and the officer came, they ran, killed him. maybe they got to the vehicle and fled. but, of course, we don't know that. they could be in the woods and that's what -- intense manhunt is for. >> jim, in terms of i.d.ing the suspects, we obviously have not been given any information aside two white males and one black male, at what point does law enforcement release that? when they believe it's beneficial to their search or a certain time perspective they sit on it and don't want to give those individuals a heads up they know who they are? how does that work out in this situation? >> yeah. it is the commander's decision. a great question, luke. it's a commander's decision to put it out and may be facing in

a case like this, they don't know the identifies. we don't know if they do or not. if there's dash cam footage of the killers on the officer's car, that would i believe to be the best possible thing or cameras at the cement plant and may not be many and dash cam in the car, present or anything on there? these guys may have not -- nobody saw them except the officer that's now deceased and may not be a photograph of them. authorities may not know who they are and so they can't release anything further because what we got may be all they have. the other hand is they may have identified someone from a photograph of a witness or something and following leads and we don't have that information. >> absolutely. jim cavanaugh, thank you so much. stay with us throughout the hour. we're going to be right back with the latest on this massive manhunt under way in illinois in a short few minutes.

doers. they don't worry if something's possible. they just do it. at sears optical, we're committed to bringing them eyewear that works as hard as they do. right now, buy one pair and get another free. quality eyewear for doers. sears optical ♪ hi, tom. how's the college visit? does it make the short list? yeah, i'm afraid so. it's okay. this is what we've been planning for. knowing our clients personally is why edward jones is the big company that doesn't act that way. what do a nasca comedian... and a professional golfer have in common? we talked to our doctors

about treatment with xarelto®. xarelto® is proven to treat and help reduce the risk of dvt and pe blood clots. xarelto® has also been proven to reduce the risk of stroke in people with afib, not caused by a heart valve problem. for people with afib currently well managed on warfarin, there is limited information on how xarelto® and warfarin compare in reducing the risk of stroke. i tried warfarin before, but the blood testing routine and dietary restrictions had me off my game. not this time. not with xarelto®. i'll have another arnold palmer. make mine a kevin nealon. really, brian? hey, safety first. like all blood thinners, don't stop taking xarelto® without talking to your doctor, as this may increase your risk of a blood clot or stroke. while taking, you may bruise more easily and it may take longer for bleeding to stop. xarelto® may increase your risk of bleeding if you take certain medicines. xarelto® can cause serious, and in rare cases, fatal bleeding. get help right away for unexpected bleeding, unusual bruising, or tingling. if you have had spinal anesthesia while on xarelto®, watch for back pain or any nerve or muscle related signs or symptoms. do not take xarelto® if you have an artificial heart valve

or abnormal bleeding. tell your doctor before all planned medical or dental procedures. before starting xarelto®, tell your doctor about any kidney, liver, or bleeding problems. xarelto® has been prescribed more than 11 million times in the u.s. and that number's growing. like your guys' scores. with xarelto® there is no regular blood monitoring, and no known dietary restrictions. treatment with xarelto® was the right move for us. ask your doctor about xarelto®. so, what did you guys they think of the test drive? i love the jetta. but what about a deal? terry, stop! it's quite alright... you know what? we want to make a deal with you. we're twins, so could you give us two for the price of one? come on, give us a deal. look at how old i am. do you come here often? he works here, terry! you work here, right? yes... ok let's get to the point. we're going to take the deal. the volkswagen model year end sales event ends on labor day. so hurry in to your local volkswagen dealr toda!

welcome back to msnbc. i'm luke russert. we have been covering breaking news out of the fox lake, illinois. around 8:00 a.m. this morning, a police officer noticed some suspicious activity around a building having to do with a cement company in that area. miles northwest of chicago. the officer pursued three suspects and then was, in fact, gunned down and killed by them. we do know that the suspects took the officer's gun as well as his mace. unclear if they took the radio. also, unclear if they were armed prior to their interaction with the officer. but since that time, there's been a massive manhunt in the fox lake area. trying to apprehend these three suspects. two whites, one black is being reported right now. the area in question is a bedroom community of chicago. but also, serves as a recreational community on the water there. there's ample woodlands. there's marshlands. there's boats and such so it's a

very difficult area to set up a perimeter around because there's so many places for an individual to hide as well as a train that services that town that goes in chicago. it's also unclear if suspects had access to the vehicle after committing this murder. joining me on the phone is phil rogers, wmaq reporter. phil, since we last talked, not many new developments here. just this ongoing massive manhunt with the masdsive amount of manpower, helicopters, blood-sniffing dogs, boats, surveillance of trains and whatnot. we expect this to be ongoing for the duration of the day and into the night if need be. >> well, we hope it won't, of course, because we hope they meet with some success here very soon. luke, there's so many variables here. number one, not the least of which is it's unclear what was happening at the beginning of

this. the cement facility was the address, the nearest address that was given for the location of where this began. it's not known whether that building played a role in this. all that's known for certain is the officer said he was in pursuit of the individuals and for whatever reason, apparently they got the drop on him. he was shot. his weapon was taken. it's unclear how much of his other gear was taken. of course, one of the more frightening scenarios would be if they have his radio and monitor the entire police search. there is no confirmation that that, in fact, is the case. but you described a scenario here that is quite accurate. there are just so many hiding places out in that area that it just presents a tremendous challenge for police and federal agents, even though there's a vast ar ma that of people working this. we know the officer. the name is not released yet publicly but it is apparent and

we've been monitoring just the tri butds that have been pouring in to his family. i just trike to read you two here. one says, your father is a hero and will always be remembered as that. the this is to his son on facebook. the reason for that is because this particular officer was well-known to young people in that community because of the role he played in the police department. he had lots of contact with high school students, with younger people. and this is especially being hard taken in that community, as word is trickling out. >> we are getting report that is this officer was a very much leader in this community. so wmaq's phil rogers, thank you. let's bring back lenny depaul and shawn henry. lenny, i want to start off with you and get back to what i was

talking with there. you have a situation where you have the trains. you don't know if the suspects had access to a car. you have all these boats there, marsh larnd. woodland. this is early september and everything is still very much in bloom. it's still warm outside. there is a cascade of issues that are stacked against law enforcement right now out of the gate. >> luke, huge issues face law enforcement as we speak. absolutely. i guess taking you back a little bit in the timeline when this thing went down, i mean, this officer, on the positive side, put out that he was in foot pursuit and an idea that, okay, these guys aren't escapees. they didn't have a plan. they didn't know what they were going to do. i don't think they planned to kill the police officer. i may be wrong. just trying to put the pieces together here. he's in foot pursuit. did they go in different directions? maybe they got in a struggle with one of them or he did with one of the guys and maybe he was

shot with his own gun. there's a lot of maybes here. we don't know why they stripped him of the equipment, that's another good question. maybe the other two weren't around and nervous and want to turn themselves in. wishful thinking here and trying to stay positive. it's a mess. there's a lot of hiding places for these guys to go to. did they get into a vehicle? it's been quiet. no carjackings from what i understand. there are folks that have abandoned or unoccupied homes. they're at work. kids are in school. they're sweeping the houses. car stops are being done. intense manhunt, luke. you know, i'm trying to stay positive and hope for the best here. >> shawn, in a situation like this where you have three suspects, whether's the mind-set of law enforcement in terms of could these suspects break up and you have three different areas where they could be hiding or two in one direction and one goes in the other? what's the sort of protocol for that? how do you approach a situation like that?

>> i think that goes to the mind-set of the officers. as you're approaching any situation, whether it be a residence or some type of a hiding spot, a wooded area, i think you have to assume that they're together. because that's the most dangerous situation if you have got three potentially armed, we don't know if they have one weapon or multiple weapons an three potentially armed subjects, presents the most dangerous situation for approaching law enforcement officers and absolutely possible this these people's broke up and they're heading if three different directions and might have three different search areas. some point, one of the other things i mentioned, luke, you know, closing in 3:00 local time. we have probably got four or five hours of daylight left as night begins to fall. this turns into a different situation, it becomes more dangerous for law enforcement. certainly a lot more difficult to identify the people. so this is a changing dynamic. the situation's going to continue to change as we move on through the day. >> lenny, another thing here is

that this area, fox lake, is relatively close to the wisconsin border. i remember when we were talking about those escapees in new york state close to the vermont board ere, you obviously some point perhaps have to alert law enforcement personnel in another state to be on the lookout, i want to get back to this idea of coordination because you have federal agencies, county, local jurisdiction and probably sure -- they probably gave wisconsin a heads up. how does that all work out as daylight slowly dissipates? >> yeah, luke, you got your lead agency, i believe the sheriff's department and the local agency involved. command posts are being set up. alerts are being sent out and happened early this morning, i'm sure. wisconsin probably has folks in the command post. all agencies are talking to each other. they're sharing information. they cultivated the sources, informants. what's the chatter in the drug communities and other

communities and whatnot? so again, we don't know what happened. we don't know why the officer stumbled on to the three. was he called into the scene as a possible break-in? you mentioned a building they were close to. we don't know if that's in play. were there weapons involved? what was their motive? he stumbled on to the three guys. they started running. he puts out he is in foot pursuit. maybe this was a struggle for the gun and they have no idea what went on. again, what iffing it to death and these are questions to be answered. >> that's so hard for us reporting on this right now with the unknown variables. we don't know the suspects or the motive. we don't know how all this happened. so it's something we'll keep an eye on, certainly, throughout the day here on msnbc. shawn henry and lenny depaul, thank you for staying with us in this hour. there's other breaking news believe it or not. with minutes to go until the

closing bell, the dow tumbling once again. we'll get the latest on that as we look ahead to the market closing straight ahead here on msnbc. across america, people like basketball hall of famer

similar worries of china's slowing economy and a possibly interest rate hike that plagued the markets last month are back. and what a record-breaking month it was. august was the worst month for the dow since may 2010. also the worst august for trading in 17 years. let's get to it with jillian tett. jillian, thanks for making the time. what do you make of this? this ongoing roller coaster. we talked anlt it last week. it was low low low then up up up. is this another correction? >> these are crazy markets. they are very volatile markets and what they reflect are two things. one is a change in market structure with the rise of a lot of computer trading and a lot of lack of liquidity. but the other thing is extreme uncertainty all over the world. today we have a situation where markets are tightly interconnected. all around the globe. and yet unfortunately, what's happening in china, what's happening in opec, those are

still a tremendous mystery to most ordinary investors and. that plays into this climate of uncertainty. >> if your concerns this morning or this afternoon about your 401(k), what should you do? hold tight? or in this situation what should you do? >> take a deep breath. don't do anything. because you are seeing incredibly volatile swings. never mind the stock market. you had oil prices 23 percent in just three days. it shows we're living in a climate of considerable uncertainty and people are trying to work out what is going on. >> we want you on here to talk about your book and you give us update on the markets. but your book, you examine what you say and a tendency amongst groups, albeit in this case many of them financial, that they engage in very close-minded narrow thinking. only focusing on themselves and not having a greater vision of what is going on around the world. you said that was the reason

behind the '08 economic collapse. elaborate on that and is that at play here. >> i do think that is in play today. we live in a global system where everybody thinks we're incredibly tightly interconnected through cell phones and airplanes and the financial markets. a -- ricochet across the entire world incredibly fast. and the vooelt although we think and fool ourselves we're interconnected, our lives and minds are incredibly fragmented. you see that in the world the fact that so many people are [ inaudible ] don't actually understand china. you can see that more importantly inside companies today. big institutions where basically the right hand doesn't know what the left hand is doing. what i do in my book is tell stories about examples of this and try to offer solutions. >> now, you are an anthropologist. >> i am, yes. >> by training, which is interesting. as well as a financial reporter. not a combination you usually see. but from my reading of this as a layman, i instantly thought one

thing we see across media is a very much protectionist idea of turf. whether it be a story. and then if something else is going on, not my problem. how much of that human nature is at play here? >> it is totally at play. and the media has silos. but also we increasingly have silos in terms of how we consume the media. one of the things that's happening is that we have all of this technology linking us inside the space that creates the illusion we're all connected. but when you choose who to follow say on twitter, when you choose what information to get, it is very easy to slide into social ghettos, to slide into an echo chamber and that creates tunnel vision and a kind of polarizati polarization. how many people out there who have actually owned 401(k)s with exposure to china, say, have ever actually read what the chinese media are saying? gone to china? put their mind into what's happening in china? we all live these lives with tunnel vision.

and that is very dangerous. >> yes the tunnel vision i would say is brought forward by social media. i agree with the premise of your book. we think we're all interconnected. we have a global perspective. to some degree it's made us smaller and more narrow minded. thank you so much. your book, check that out. and thank you for the update on the market as well. that's it for us. i'm luke russert. craig melvin is up next with more on the markets as well. the man hunt in illinois. a press conference is happening soon. breaking coverage continues after this short break.
