. that's it for us tonight. if you only knew what happened in the commercial break. i'm don lemon. i'll see you back here tomorrow night. "a.c. 360" starts right now. good evening and thanks for joining us. we begin tonight with breaking news and a troubling question. was the attack on that mohammad

cartoon contest in texas the first isis attack in america. and we have new information about one of the contacts elton simpson may have had with an isis recruit. isis has claimed credit for the attack which the white house today called an attempted act of terrorism, but stopped short saying is isis ordered it. the investigation is active to say the least. our correspondent pamela brown has the latest. >> reporter: cnn has learned one of the gunmen elton simpson, directed a message on twitter to this account, believed to belong to an american member of al qaeda in somalia, calling attention to the planned prophet muhammad cartoon event in the dallas suburbs, less than two weeks before the attack. on april 23rd simpson tweeted to the jihadii about the event, when will they ever learn? that same jihadi tweeted out about the event, referencing the "charlie hebdo" attack in paris. it's time for brothers in the u.s. to do their part. it's one of several twitter connections that cnn has found that simpson had online with

jihadists overseas. they're now trying to determine if he was trying to get the jihadists' attention or plotting with them. the use of social media by terrorists is a daunting challenge. >> it allows like never before for overseas groups to reach into oir communities to recruit, to radicalize as well as to target our citizens. all in a very simple easy-to-use way. >> reporter: back on april 10th in a private twitter message intercepted by the u.s. cnn is told that simpson discussed with others how to get to syria. bring your passport. if you have $4,000 that's enough to travel he wrote. and hours before the attack simpson urged his twitter followers to follow a known british intelligence hacker a significant figure in isis. >> somebody known as a propagandist within isis somebody known for his hacking skills who has targeted the u.s. military in previous hacks. >> reporter: tonight, we are learning more about the gunmen's

past. elton simpson was captain of his high school basketball team. his former lawyer remembered noticing how religious he seemed. >> he was a very devout muslim. i did get the sense that he was trying to convert myself and my staff and the people that were working with me. >> reporter: the second gunmen born to a pakistani father and american mother attended to a prestigious private school in pakistan. after his parents divorced he moved to the u.s. with his mother and brother, where he was popular in school and played the lead in his high school production of "bye-bye birdie." tonight his family is in disbelief. >> whoever he was with talked him into it. >> that's how you feel about it? >> there's no other way it would have happened. >> pamela brown joins us from phoenix. what more are you learning about how the guard was able to talk down these guys armed with assault rifles? my understanding is he had a handgun and he was under fire. >> reporter: absolutely. it certainly was not a fair

match, anderson. and it's really incredible that this officer with the garland police department he was a traffic cop, that he was able to kill the two suspects with his work pistol. it was him up against these two suspects and bulletproof vests, carrying assault rifles. and within 15 seconds, it was over. the two suspects were dead and anderson we have learned from officials that that officer, the traffic officer and a security guard who were in their cars stationed at the entrance were just minutes away from leaving the entrance. so he prevented what one official i spoke to said a mass massacre there, where the event was being held. because there were 200 people inside. they would have been walking out, and had those two officers not been there, the gunmen could have pulled up and created, as we know a much worse situation, an attack that was not foiled. we have learned, anderson, that they were intent on wreaking havoc. as we know they had those

assault rifles. they also had two long guns and four handguns we've learned, inside their car. >> that sounds like the definition of calm under fire. now to baltimore, where the police commissioner says in an exclusive interview that he was surprised to learn that six of his officers would be charged in the death of freddie gray. the police commissioner is also trying to assure the community that change is coming. a goal shared by the new attorney general loretta lynch. lynch was in baltimore today meeting with police officers city officials, and community leaders as well as with freddie gray's family in a private meeting. she said what she heard is how people in baltimore are committed to improving the relationship between the police and the community. in a moment we'll hear from a law enforcement officer who says the charges against the baltimore police officers constitute an abuse of power and are not about justice, but about revenge and appealing the mob. but first, cnn's evan perez sat down today for an exclusive interview with police commissioner anthony batts in his first interview since gray's death. take a look. >> tell me your reaction when

you found out that the state attorney was preparing to bring charges last friday. >> well i find out hat state attorney was going on and what she was going to present probably about ten minutes before she went on. she gave me a phone call and told me what she was about to do and that she was going on live. she told me what the charges were. >> what were your first words out of your mouth when you heard that? >> i don't want to get into that so much. i can say that i was probably surprised, you know, by the information that i heard. again, my mind started going to what's going to be the response in the community? what's going to happen in the community? i went to what's going to happen with my officers. >> did you have an agreement ahead of time that you would get more notice item? in previous situations like this you usually give the police some notice so they can be prepared for whatever the community reaction is going to be. >> i had one meeting with state's attorney and her

executive team and executive staff and we sat down and she shared is with me she was concerned about the amount of information that was going out and she wanted to limit that to which she heard me give a news conference later that we were limiting the news conference that was going on. that came out of that meeting. from my standpoint doing this before i want to be as transparent as possible. but the state's attorney has to try a case. so they're very concerned with the level of information that comes out. so i have to strike a balance. the balance is trying to give as much information as we can, without impacting her case as she has to go forward. i had pretty close to 45 50 plus employees on this case. i pulled them off of homicide cases, i pulled them off of robbery cases, and we put this task force together with my lab personnel, we brought our training staff, and we put a lot of work into this case. and my focus was not just and i don't have the luxury just to focus on what happened inside of that van, the booking van. i have to answer questions of

what started in that officer's day, what every one of those officers did, what were the gaps and have to fill in all those blanks. so my 40-plus task force were focused on getting the entire complete story. >> so you have 45 50 employs, my understanding, 30 plus crime investigators who are focused on this on this case. and then to have them usurped by another office doing an independent investigation, from what i understand they had four investigators doing this what is that like? what does that feel like? what does that feel for your employees? >> if they could do with four with what we did with 40 they're very good at what we do. we looked at everything. >> i know you want to talk a lot about how you're going to rebuild trust with this community. how do you plan to do that? >> it's clear the day i stepped on the ground here in baltimore, that there's a lack of trust within our community and the police department and certain parts of our community. so we've been trying to do that from day one by being

transparent, by being open. when we make mistakes to share with the community, when we make mistakes. >> the freddie gray case then, to you represents what? an aberration? something that simply set you back? >> no with i think we're going in the right direction, what i'm trying to say. by every metric you measure a police department on we've hit a home run and we're going in the right direction. there's a lack of trust within this community, period bottom line. that's going to take healing. that's going to take us acknowledging as a police department not just here in baltimore, was law enforcement as a whole, that we've been part of the problem. >> anderson what you hear from the commissioner there is between the lines. he's talking about the thoroughness of his police investigation and he's making a contrast with what many people say was a hasty decision by the state attorney to bring charges against these six officers, and he's drawing a contrast between those two cases, anderson. >> evan in your interview, are you saying that the state's attorney only had four

investigators on this case? because she made a big deal about how from day one, her office had been investigating, she pulled in resources. you're saying they only had four people working on it? >> well she had four investigators who were leading this case. she had a few other staff, but in comparison to what the police threw at this case anderson she had, you know, 40 50 people who were working on this from day one. so what he was trying to say is that they had a very thorough case and drawing a contrast to what she had done. >> there's also now been a couple of interesting things evan, that have come out. first of all, two of the names that the state's attorney put out, i guess in the charging documents, were incorrect. and they actually were the wrong person's names. and i also understand now, one of the officers is disputing in court, saying that the knife that freddie -- that the arrest was illegal, and saying that the knife that freddie gray was, in fact carrying was illegal and wants it released so they can

show that. >> well that's actually one of the things that you see differences between these two investigations. the state investigation and the one that commissioner batts' office was doing. according to marilyn mosby, when she spoke at the war memorial across the street here the knife that freddie gray was carrying was not illegal, according to her, in the state of maryland. however, this police department says that the knife violated the city code. so what you see the officers now trying to do is draw a distinction between the two cases, the two investigations that are ongoing here and that's just the beginning of what this state attorney is going to have to face in defending her case anderson. >> evan appreciate the update and the interview. a lot to talk about. joining me now is milwaukee county sheriff, david clark. also cnn legal analyst and a former federal prosecutor sunny hostin who we should note is friends with the mayor of baltimore, and jeffrey toobin. sheriff clark, you heard that

investigators are announcing the knife was illegal, two of the names were wrong in the charging documents. you said that marilyn mosby offered these officers up as sacrificial lambs. can you explain what you mean? >> sure. first of all, when you rush a decision you can see, and i think this thing is going to unravel, you can so eee the problems that you have. the brilliant legal scholar said that her decision was rushed and it was done for mob control and i concur. she has the right to charge these individuals and she has to move it beyond a reasonable doubt. when she went down that political rabbit hole and making claims about i hear the voices young people it's your time, no justice, no peace, those aren't legal terms, those are political statements. once she went down that rabbit hole i said that these officers are political prisoners and i stand by that. i've investigated with a team of investigators that have investigated over 400 homicides in a four-year period.

i've supervised and assisted at charging conferences and i have never had a criminal complaint issued on a homicide case. and i'm talking about a standard one, not as one as complexa as within 24 hours. and i don't care that she had some investigators parallel and alongside. these things are -- have volumes of reports, evidence has to be gone over. she should have just taken her time before she made this decision and she did not. >> jeff toobin what about that? >> well we'll see. my friend, sheriff clark, makes a very good case against this prosecution. however, you know, freddie gray woke up healthy on april 12th and he was didead by noon and the only people he was with was police officers. so the idea that he was dead as a result of a crime makes a certain amount of sense. whether she should have investigated longer and whether these tribes will stand up in court, we'll see. and i think it's important to say, we will see. and she may turn out to be

right. >> sunny, what about that? i know you've raised some concerns about the speed of this. aren't regular people charged with crimes this fast all the time? >> not necessarily. especially when you're talking about a complicated homicide case. and i have raised concerns about the haste and in terms of bringing the charges. i had concerns on the day that it was announced, quite frankly, because i did hear her say things like, i heard your calls for no justice, no peace. well guess what prosecutors are not allowed to take the citizens' demands into consideration. in fact most of the time we bring cases despite and in spite of what the citizenry wants. so i was concerned about some of the statements that she made. and i am a bit concerned about fact that the coroner's report was given to her merely 24 hours before she made, you know filed those charges. because that is the linchpin of

this case. that autopsy report. and i don't think that she would have had the time to have independent experts review the coroner's report. but to jeff's point, we're talking about a young man who was otherwise healthy, who ended up dead within a severed spine after being in police custody. so the fact that something criminal happened is probable. but i just do have some concerns about the speed within which she decided these charges. >> sheriff, the fact that the state's attorney only gave the police commissioner a ten minutes' heads up what do you make of that? how would you feel if that was the case? >> extremely problematic. like i said with my experience a charging conference, usually the prosecutors will work with you. and usually you're alongside the prosecutor. i don't mean the police commissioner but the investigators. and i've been a part of that and then it was my job as the lieutenant of the detectives or the detective to keep my superiors informed. but ten minutes seems a little unusual there. and you know you don't get a

do-over in a complicated case like this when you make mistakes early on you never get a chance to recover and this was a bad situation to begin with. that wasn't miss mosby's fault, but her job was to slow it down and get it right. and i think she was like alan dershowitz said, she was more concerned about quelling the masses and calming down the angry mob than she was about doing this thing right so the right ending occurred. something happened to freddie gray but that doesn't necessarily mean and i don't know the facts of the case but that doesn't necessarily mean that the police officers had to do anything with it or that there was criminal intent for a charge of second-degree murder or manslaughter. >> i actually think the lack to have communication was a good thing, not a bad thing. remember in ferguson everyone was so concerned that a police investigation -- that a prosecutor's investigation of the police they were too close

together. they were -- you're ordinarily teammates. look this was basically an adversarial process here where you had a prosecutor deciding whether the police officers should be charged. i think a certain amount of distance and a certain amount of the prosecutor clearly being in charge was a good thing. >> jeff you don't believe politics played a role the desire to bring calm to the city played a role in this? >> i don't know. i don't know. and i think we will learn that as the facts are unfolded. look i certainly thought it was very fast. i understand why people are criticizing. these early mistakes like the wrong names on the forms, do suggest undue haste. but let's see if she can make her case this court. if she can, she didn't go too fast. >> great to have you on. a quick reminder set your dvr, you can watch "360" anytime you want. coming up, a police officer kills a man in his own home a man who hadn't committed any

crime and a man who other officers said he had his hands up. not only has the officer not been challenged but it took a year for his name to come out. was there a cover-up? we investigate on that, next. the beautiful sound of customers making the most of their united flight. power, wi-fi and streaming entertainment. that's... seize the journey friendly. ♪ the network that monitors her health. the secure cloud services that store her genetic data. the servers and software on a mission to find the perfect match. and the mom who gets to hear her daughter's heart beat once again. we're helping organizations transform the way they work so they can transform the lives of the people they serve.

whether it's in baltimore, ferguson or staten island, there is a perception in many communities in this country that race is a factor in the way that police do their jobs. a new poll ask people about race, police and the use of deadly force. 37% of the white people who were asked said police are more likely to use deadly force against a black person while 79% of african-americans said the same. it was just a very small percentage of those polled said that police were more likely to use deadly force against a white person. most of the rest said race does not affect the use of deadly force. it's true the nation has been focusing on a string of death of young black men killed by police. but right now we want to tell you about a case in virginia a white man killed in his own home by a police officer. nearly two years later, that police officer is still on the force, still working, and no

charges have been filed. it took more than a year for them to say who pulled the trigger. >> reporter: this is how john gear spent the last 45 minutes of his life. standing at his front door hands up talking with fairfax, virginia police. that's him in the white t-shirt. this picture is from a neighbor's cell phone, taken just minutes before john gear is jot dead. >> you had one officer standing here he had his gun drawn, officer torres had his gun drawn and pretty much pointed center mass the whole time. >> gear's friend of more than 25 years, jeff stewart, was there, and remembers seeing officer adam torres on the front lawn. in this photo, you see his weapon's raised pointing directly at john gear. it was the middle of the afternoon, august 2013. john gear's girlfriend of 24 years had called police saying she was moving out and that gear was throwing her belongings here on the front lawn. it was called in as a domestic dispute. listen to the 911 call.

>> does he have any weapons in the house? >> um shotguns handguns, the kind of guns he has, but they're in a case. >> reporter: turns out john gear does have one gun out of the case a .357 but it's in a holster. he even shows it to officer rodney barnes a trained police negotiator also on the scene. that's barnes in the blue vest to the left of officer torres. barnes will say later in taped interviews with investigators that gear never threatened police or ever took his gun out of the holster. >> just come to the door. >> barnes talks calmly with gear for nearly an hour trying to convince him to come out of the house. >> he said i don't want anybody to get hurt. i said i don't want to get shot. i don't want anybody else to get shot. >> reporter: gear, a self-employed father of two teenage girls, refuses to come out, unless torres and the other armed officers back far away.

officer torres still aiming his gun, is making gear nervous. >> he said hey, can you not point that gun at me? can you get officer whatever to put away his gun. >> a few times, gear asks permission to move. >> a couple times, he needed to scratch his nose. he would say, hey, i'm going to scratch my nose and he would slowly take his hand and scratch his nose. >> but officer torres remembers it differently. >> he brought both his hands down in a quick motion towards his waist and i fired a scot right through the screen door and it hit him. >> reporter: a single shot and john gear goes down in his own home. remember he hadn't committed a crime and he wasn't holding a weapon. jeff stuart saw his friend get shot. >> john was hit lower left side on his rib cage. i watched from up there, and as soon as he shot he pulled his hand down to here he spun inside the house and pulled the door shut behind him. >> and you could see where his

hands were the moment he was shot? >> his hands were above his shoulder. >> reporter: just like officer barnes the police negotiator remembers it. >> i heard a pop, you know, and he had just scratched his nose and put his hand back up there, and it just happened so fast and i'm like he shot him, like to myself who the [ bleep ] shot? >> reporter: and there's more. right after officer torres shot gear he apologized for it and then blurted out that he'd had a fight with his wife just minutes before arriving on scene. >> for a split second i just thought, um whether it was just out of anger that this happened but it wasn't out of anger. >> reporter: but torres quickly backtracked and decided he did the right thing. listen to what he told investigators. >> it was justified. i have no -- i have no doubt about that. at all. >> reporter: justified? the other officers on the scene

disagree. listen to officer barnes. >> i'm not here to throw him urn the bus or anything like that but i didn't see what he saw. >> reporter: and another officer who was armed with a rifle at the scene later told investigators he didn't see any aggressive moves by gear. in fact that officer said he never even took the safety off his rifle. and look at officer david neil to the right of officer torres in this photo. his gun is out, but pointed at the ground while officer torres' weapon is aimed at gear. his finger is on the trigger. >> every once in a while, i put my finger on the trigger, just to -- in case i -- in case i wanted -- just a few times, i did it. >> attorney mike lieberman, who filed a wrongful death lawsuit on behalf of gear's family says torres violated department policy by having his finger on

the trigger. >> it violates the universal cardinal rules of safety for anyone with a weapon but certainly police with a weapon. you never put your finger on a trigger unless you intend to pull it. >> the lawsuit list the officer who killed john gear as john doe 1. that's because for 16 months fairfax county police refused to tell the family and the public who pulled the trigger. >> do you think police are trying to sweep this whole case under the rug? >> well for 16 months, there was no question in my mind there was stonewalling going on. they did not want the public or the family to know anything that was going on. >> officer torres' attorney declined to speak with us so did fairfax police. though police did tell us officer adam torres is still employed we the department, a assigned to administrative duties. the u.s. department of justice took over the case in january 2014. >> so where does the case now stand? >> well we know that john

gear's family settled in april with fairfax county for $2.95 million. so that's the civil suit. that's over and done, but it has been a really long and painful battle for this family. he was shot back in june of 2013 so it's been almost two years. and what makes it more painful, when john gear was shot the police didn't call for the ambulance, no one went inside to save him, instead, they called for an armored vehicle, a tank with a battering ram to get inside. no one went in to try to help him or check his condition, they thought maybe it was unsafe so they waited on that instead of calling for paramedics or nearby ambulance. >> what have you learned about the officer involved in the shooting? >> adam torres was 35 years old when the shooting happened and he is the subject of five internal affairs investigations including one about this case and one about a case where he's accused of having a major meltdown in a courtroom and screaming at a prosecutor but

he's still on the job, even though it's administrative duties and still getting paid as the justice department tries to figure this out. >> randi, appreciate it. just ahead, new polling on what could be the biggest challenge hillary clinton faces in her bid for the white house. and how she stacks up against the just-expanded republican field. also tonight, new details about the mysterious and sudden death of david goldberg husband of facebook exec, cheryl sandberg. the microsoft cloud gives our team the power to instantly deliver critical information to people, whenever they need it. here at accuweather we get up to 10 billion data requests every day. the cloud allows us to scale up so we can handle that volume. we can help keep people safe and to us that feels really good. covert ops? double agents? spy thriller? you don't know "aarp" thanks to the aarp tek program

well in the last 48 hours, the republican presidential field has doubled. today, former arkansas governor mike huckabee said he'll make a second run for the white house. his announcement comes a day after ben carson and carly fiorina declared their candidacies. so does a bigger field necessarily mean a more competitive primary race? there is new polling on that tonight. and also on how the republican hopefuls stack up against hillary clinton. cnn's john king is here to walk us through it. so john, a lot of movement in the republican field in the last few days. >> three new candidates anderson up to six. this is not support for these candidates. 74% of republicans do not support marco rubio today.

the question the nbc and "wall street journal" asked, could you support these candidates? rubio, bush 52% said they could support rubio if they were the nominee. ben carson and carly fiorina got in yesterday and they're lower down. we have a top tier you might draw the line at cruz. cruz paul walker bush rubio. this is a wide-open race. a new iowa poll out tomorrow anderson. interesting to see the state of play in the first caucus state. >> and how do they do against hillary clinton? i know in that same poll, it talks about that. >> well, she beats them all. she beats all the leading republicans. if you're a democrat you say, great, right? but these aren't blowouts. clinton versus jeb bush 49/43. clinton versus scott walker a bigger lead 50/40. here's the interesting one, rand paul runs closest among the leading republican candidates

37/44. rand paul tends to get more independents going his way. hillary clinton leads in all of them. the one thing they are happy about on the democratic side anderson she largely keeps together the obama coalition, african-american latinos, women, generally. but if you're a republican you say, hey, she's the overwhelming front-runner she's the only democrat really serious right now, and we're close. so we're going to have a competitive campaign. >> and have her numbers taken a hit at all because of the news regarding donations to the clinton charitable foundation? >> that is the glaring question and a big question. in the nbc/"wall street journal" poll as happy as they are they beet all the republicans in lox, this is the equivalent of a five-alarm fire. 25%, one in four american voters right now say they think hillary clinton is honest and straightforward. 38% thought that a little over a year ago. is only 25% of republicans view her as honest and trustworthy. they know in the clinton campaign this is a big problem. this they need to fix. now they have the time and the resources and energy to do it, but watch that number. hard to get elected president if only one in four voters think

you're honest. >> i've heard they've launched a new website to try to counter accusations against the foundation. >> they call it the briefing and welcome to the world of modern campaigns and modern media. it's a website. the new book "clinton cash" hit bookstands this week. he says it's full of republican smears and mistruths. this is a new way in politics a smart way in politics number one, it gives democrats a place to go and they hear something and attack on hillary clinton, they want their side of the story. they go here. number two, if you go in a search engine and look for information, yes, you'll get cnn.com, yes you'll get republican websites but now you'll get the hillary clinton campaign perspective too. and the you scroll down a little bit further, it also anderson says donate. a little choir practice and raise a little money. >> john king thank you, fascinating. a quick programming note to tell you about. in the top of the hour the cnn special report "murder at the marathon" takes an in-depth look at the boston marathon bombing. our deborah feyerick retraces the hours and days after the

exclusive hotel near the mexican resort home of puerta vallarta. a day later, he was exercising on a treadmill when he slipped, fell hit the back right side of his head creating a 3-centimeter gash. >> people can have fairly small external injuries especially to the skull and to the scalp, and that can bleed quite significantly. and it all indicates there's some type of internal injury to the brain. >> reporter: investigators say goldberg within the to the gym at about 4:00 p.m. his brother, robert told authorities that goldberg normally worked out for two hours. when goldberg didn't return from his workout, robert went looking for him and found him on the floor in a pool of blood 2 1/2 hours later. his brother called for help but by the time the silicon valley exec got to the hospital it was too late. he was pronounced dead according to the attorney general's spokesperson.

joins me now. it's incredible when i read about this it seems to so random and then you actually look at the number there are actually a lot of accidents on treadmills but can somebody fall with enough force that they end up just bleeding to death? >> it's a very unfortunate combination of events it seems, in this case. as you said there are a lot of injuries due to treadmills and tense of thousands of people go to the e.r. every year with these. usually, though they're more minor injuries or sprains or leg injuries. if you just fall the wrong way to the wrong angle, you can severely impact your head. and we know the brain is var vascular there are a lot of blood vessels there. and he was unconscious, because he hit his head. he had a big, deep cut, 3 centimeters long apparently. and that bled. if he had tnt been unconscious, if he was bleeding he could have got medical attention. >> if there was somebody else in the gym. >> but to bleed unattended for potentially two or three hours,

could be enough for him to lose a massive amount of blood. >> and the authorities said the death was called by severe blood loss and hypobulimic shock. >> it means you don't have enough fluid in your blood vessels for the heart to pump blood to the rest of your or began organs. >> because you lost so much blood, your heart can no longer start pumping. >> and your organs start to die off because they're not getting the blood and oxygen they need. >> is it possible that someone would collapse for some other reason and then hit their head? >> it's very possible. you could have an arrhythmia a heart attack but they are calling it an accident which suggests that after the autopsy, they didn't find evidence of heart disease or a stroke or something else that happened prior to the fall. >> one of the things i was reading is that was sort of treadmills are becoming more and more sophisticated, with more electronic things more things to kind of divert one's attention, actually it's led to an increase in accidents, because people have -- are

multi-tasking while they're on the treadmill or watching television or not paying attention. >> exactly. i think this is a good reminder. we're not going to tell people not to go on a treadmill. he was exercising while on vacation which a lot of us don't even do. but the treadmills these days are complicated and sophisticated. if you're using a new machine and don't understand the different levers and knobs, ask for help. make sure children don't have access to these treadmills if you have one at home. >> a lot of the emergency room statistics i have looking at involve children who were wandered on to the treadmill. >> pediatric er visits. you want to make sure children have no access to those types of machines. but even for adults, we have to be may findindful if we're listening to music. you're on a machine that's moving and will keep moving. >> dr. raj, thank you so much. appreciate you being with us. an incredible story about a brave mom, not even gunshot wounds could stop her from protecting two of her young kids

time now for the ridiculist. tonight we're adding the bear who messed with carl. who's carl you may ask? carl is an ex-marine, occasional barroom brawler, and unafraid of a little close combat animal style. >> the man or beast that i run from ain't been born. and its mama's already dead. >> oh, yeah. we're just getting started with carl. by the way, if what carl said sounded familiar it's because that's how wolf blitzer begins "the situation room." anyway before we hear more from carl let's have our affiliate reporter lay out the basics of what recently happened at carl's california home. >> the other week lacy the dog, he loves like a daughter started whimpering outside. carl ran out and there it was. a bear who had no idea what world it just stepped into. carl's world. >> okay. can we get some popcorn? because i think i'm going to need some popcorn. >> i ain't running from nothing. i never have in my whole life and i ain't gonna start now.

and you're not going to sacrifice my babies for some damned bear. >> okay first of all, this is just like a movie, i cannot believe this. second of all, i would like to announce that carl is cnn's newest homeland security adviser. >> and i raised both hands in the air and i cussed at him. yaah get out of here you [ bleep ]! >> all right. i think carl may have missed his calling as a life coach. i'm going to feed to hear that again. let's replay that. >> yaah get out of [ bleep ]! >> if that is not my new ring tone, i don't know what is. so just to recap, carl has rushed o you have the house and is hurling obscenities at the bear. your move bear. >> he looked at me like go f yourself. what happened next you ask? i certainly did. i don't even know how to describe what happened next. >> reporter: what happened next can only be described as insane. carl landed a whirling haymaker

punching the bear right in the face. >> a whirling haymaker! okay for those of you following along at home the bear is now joe frazier, carl is mohammad ali, and carl's portion is basically madison square garden. >> he come up like this and he turns, boom! i hit him hard. damn near corkscrewed his head. >> before you start tweeting me i don't necessarily support or recommend punching bears in their heads, not at all. i want to be clear on that. that is not something i'm calling for. also you might be a little skeptical that things happened exactly how carl said they did. fortunately, the local news interviewed a witness. >> reporter: he says the bear was a bit shorter than carl but still a formidable opponent. >> wait a minute the bear was a bit shorter than carl? are we sure the animal carl attacked was actually a bear or did he maybe just throw a punch at i don't know a pudgy labrador retriever in the middle of a yawn? that would be awful. this whole thing is bizarre.

whatever it was, carl's message was received loud and clear. >> this guy's a jerk, but he ain't been back since he got smacked by carl. >> wise words spoken about carl by carl. as for the bear who messed with carl it's it's gone to hibernation, apparently on the ridiculist. that does it for us. thanks for watching the cnn special report "murder at the marathon" starts now. >> the following is a cnn special report. >> this is what they did in boston. >> oh, my god! >> but where did they go? >> less than a half an hour after they did this, they are thinking about what kind of milk to buy.
