lying there on commonwealth avenue today. sources tell us that that truck driver that has been identified as being involved in this deadly hit and run is a woman, a woman who worked at a nearby construction site. now, police have not yet named the victim and that leaves residents in this area wondering, is it a neighbor that they knew who was out walking or jogging when winn she was killed? just outside the crosswalk at busy braddock road and commonwealth avenue, the victim's body was hidden by a tent. it was around 9:20 this morning when she was struck by a large truck that kept on going. this is what a witness told her neighbor. >> she said she heard someone yell "hey, hey, call 911." i just called 911 and she came around the corner from her garden and saw the woman in the street and i guess the truck was still driving at that point and from what i had heard, they didn't know if the truck knew it had hit anybody, but i don't know if that's the case. >> reporter: investigators spent six hours at the scene reconstructing what might have happened. the force of the accident so great, the victim was killed

instantly. it's unknown whether she was walking or running and whether she was in the crosswalk when she was hit. chester taylor lived just down the street from the intersection. >> well, i was thinking, you know, gee, i wonder if i knew the person because i've lived here for 20 years. and then i thought about some of the people that i know that run in this area. >> reporter: residents fear the victim could be a neighbor and they are upset the truck driver didn't stop. >> i just can't believe that they didn't call 911, you know, immediately. it's very tragic and they might have been at fault but then they are going to have to face the consequences anyway. >> reporter: coming up on news4 at 6:00, a look at the change recently made at this intersection that was designed to keep something like this from happening. back to you in the studio. >> julie, thank you. now to a story you will see only on news4, a quiet community

in montgomery county is rattled after a brazen robbery in the middle of the day. police are looking for the man who stormed into the clarksburg pharmacy around 10 this morning, showing a gun. it's here on string town road near highway 355. the robber forced two workers to the ground there he then walked over and stole prescription medications. one woman who work there is told us this type of crime is rare in the area. >> it's a very nice area, so it's very weird to have somebody just come in and think that they can do something like that. >> all clarksburg area schools sheltered in place for about an hour and a half. in about a half hour, we will have a live report with more on the drugstore workers and what happened inside. it was an explosive threat against white people and it was posted on twitter. this threat promised a purge. and in response, police in la plata, maryland, increased their patrols and arrested the man who made the tweet. but as news4's chris gordon shows us, some people in that

community, they are still concerned. >> the tweet was to kill people in la plata. >> reporter: la plata police started getting calls about 4:45 yesterday afternoon from residents reporting seeing the tweet, which says -- >> we took it very serious. in today's society where we are seeing mass shootings at schools and at malls and churches, we have to take it serious. >> reporter: 379 concerned citizens posted messages about the threat on the la plata facebook page. many people stayed home and police say traffic was noticeably light at many of the la plata shopping centers last night. >> it is very scary that we are not very nice to each other. i just don't understand that. >> reporter: suspect shot and published this video behind a charles county sheriff's office in waldorf, maryland, suggesting he would turn himself in, but he didn't. >> it's good. like the tweet wasn't even that serious.

>> reporter: police arrested 20-year-old carlos hollins of waldorf, maryland, charging him with making a threat of mass destruction. [ knocking ] hello, this is chris gordon, news4. i knocked on the door where his family lives in waldorf. there was no answer. a neighbor who knows him says hollins has plenty of white friends, so the threat may not have been serious. >> you know, i think it was just something he said without thinking all the way through, you know, playing around and it kind of went, you know, too far, got interpreted the wrong way. >> reporter: ahead, what's next for the suspect who threatened to kill people here in la plata, coming up on news4 at 6:00. in charles county, maryland, chris gordon, news4. we are learning new details now about the woman charged in that attempted abduction of a child on metro. court documents identify her as monique mcknight. but she told police she also goes by debbie tennessee h mcknight is accused of trying to grab a 3-year-old girl out of

her stroller on an orange line train. it happened at foggy bottom yesterday. other passengers managed to free that toddler and hold mcknight until officers got there. the victim's mother told police she does not know the suspect. a police officer stood guard at a school bus stop in prince william county today after a man exposed himself to a high school girl. the 17-year-old says a man exposed himself to her, made obscene gestures as she was walking to the bus stop yesterday. we are told the man was standing in a wooded area near savannah drive and woodway place in wood brick. the teenager is a student at nearby hilton high. >> sickening in this day and society but you know, become the norm, because people do what they want to do when they want do it and don't fear the consequence. >> really disturbing. i'm lucky i didn't see it but just to hear that there's people around the area just shows that we need to, like, take extra precaution. >> prince william county schools did send out a notice about what happened to the other schools in the area and at this point, no

one has been arrested. we are watching more showers out there. >> and also the big question now, is -- when is this heat wave gonna head out of town? >> the good part about that, wendy, the heat wave heading out of town just in time for the weekend. we have got a great weekend in store, really today just been on the hot side and the humid side. temperatures today well into the 90s once again, we are tracking just a couple of isolated showers and thunderstorms. yesterday, we mentioned the fact that we would see the showers back toward the mountains, we have those back toward winchester, hardee, hampshire and west virginia. we also mentioned the bay breeze, could see a couple of those storms much the bay breeze has come n you can actually see the line here that has developed and you could see it right here. we are going to continue to see more showers fire up here but right now, taking a look at a couple of the showers around bethesda, rockville, 270, 495, right on down 495 to the east of oxon hill, clinton, an area that has seen storm after storm, so you have got another one down there, this is where we are seeing lightning, too, we can't

rule out an isolated shower for the games this evening. 91 degrees, heat index up to 94. as you move on through the rest of the night tonight, jaguars taking on redskins at 7:30 out at fedex, once again, can't rule out an isolated shower, the most part, going to be hot and humid for the game. guys? >> all right. that final preseason game with the skins kicking off here on nbc4 in about two and a half hours. >> there are a lot of jobs on the line, as you know, but a lot of the talk at fedex field is about this big change at quarterback. >> our jason pugh and carol maloney are on the field right now. >> yeah the wild week for the redskins kicked off on monday when head coach jay gruden announced the team early that morning that robert griffin iii was no longer the starting quarterback, going to go with kirk cousins. >> not expected to play tonight, colt mccoy will take all the snaps, all the starters and top backups, they are not playing. but they are behind us now going through a workout, since they are not going to get into the game tonight though. but robert griffin iii still the spotlight. he was on the field working out.

he will take his concussion test tomorrow. the bus pulled into the stadium about 3:30 this afternoon. first guy off, jay ground, head coach, looking like he is all business. tonight, starter colt mccoy, again, he will plate entire game, barring an injury. mccoy played the best really of the three quarterbacks this preseason, albeit, all against back backups. the focus on robert griffin iii and what should happen to him after his concussion. we caught one former skins qb mark brunell to gave us his take. >> louvre for him the last couple of years but came in this league impressing a lot of people. he had quite the rookie season, but there comes a point where sometimes a quarterback just needs a fresh start and maybe that's best for the team. maybe that's best for rg3, just to get somewhere else in my opinion that can allow him just to get going again. >> now, brunell did add if he does stay about the team this

year, whatever role, second string, third string, he does not expect robert griffin iii to be a distraction to his teammates. media, yes, maybe, but not his teammates. >> final cuts for the redskins will take place on saturday at 4 p.m. the roster has to be down from 75 players to 53. some people think robert griffin iii might be amongst the players cut so.think he might be on the roster, we will have to wait and see. for now, back to you in the studio. >> thank you both again. tom brady will play in the season other against the steelers next weekend a federal judge dismissed brady's four-game suspension for his alleged role in deflategate during the afc championship. the nfl says it will appeal that decision but it will not seek a stay to keep brady off the field during that process. the judge says commissioner roger goodell went too far in his punishment for brady.

new england fans appear to agree. we have been supporting him all along. we knew he didn't do anything and just proves it. they had no case. unbelievable. what a waste of money for the nfl. >> you know, brady was never guilty and just ready to start the season. >> brady, who went on to be last season's super bowl mvp has maintained all along that he had no role in deflating game balls. the appeals process could take months. we would like to know what you think. was the punishment that goodell gave brady too harsh? you can weigh in online or by text the number on your screen. checking out those who have respond sod far, appears most of you say no. we all know that many of the water pipes in our area need some updating. but earlier today, we got a pretty cool look into our area's underground past. check out this 100-year-old pipe. it was pulled out of the ground earlier today in mount rainier, maryland. this is made of wood, long before the wssc installed the moatal pipes in the 1940s this

is what carried fresh water to your homes. this wood pipe is just four or five slots of wood pushed together with some wire. >> to look back and see how water was delivered 100 years ago and the technology's very different today, much more reliable, but i say that with a little bit of hesitation because you look at this 100-year-old pipe and it still looks pretty good. >> yes, it does. the wssc tells us they plan to keep some of the old wooden pipes as artifacts for their museum. the u stilt pulling out these pipes to install more than two miles of brand new ones. lone survivor. what's being done now to support the woman who lived through that on-air ambush in virginia. and instead of murders and gun violence, we are going to show you something positive in a d.c. neighborhood, a neighborhood that needs it. a mother is outraged after her 7-year-old is dropped off miles away from his home by the school bus. coming up on news4, had

what did iran's supreme leader get in the nuclear deal? to start with, $100 billion. they keep their nuclear facilities and ballistic missiles. there won't be surprise anytime-anywhere inspections.

thunderstorms and a really nice bond. let's show but what's happening outside right now. temperature-wise, it has been hot today, saw a hive 95, back down to 91 at the airport. 91, gaithersburg, 29, fredericksburg, right now, 39 in louden county toward leesburg. cooler toward the shenandoah valley, 84 toward luray. here is the radar, not much going on most of the region dry. along 81 near win chester, watching what is going on in southern maryland and parts of the district, all because of the seabreeze -- rather the bay breeze coming off the chesapeake, making its way inland. seeing a line of showers and storms developing here, the heaviest storms over southeast, over toward the national harbor area and we have got this one storm up here toward the bethesda region. this one, stronger a little bit earlier, now just heavy rain, the wildwood hills area, bethesda, the mall, democracy boulevard here and along river road, coming in toward the districts. now, as we move down toward the

south and east, look at this one, over nats park, here's nats park, the storm along 295 here as it makes its way down toward silver here, the schefferly area, the clinton region, this one just south of alexandria, right on top of national harbor. we do have some very heavy rain happening there. this is our camera out toward national harbor. i apologize for the nice little spider web we got going on there look at that the national wheel has been stopped twice today as a result of thunderstorms in the area, that what's they got out there right now, very heavy rain happening down toward national harbor. if you're thinking about heading down toward the game tonight, we take on the braves down toward nats park, can't rule out a stray shower or storm, we are going to get the game in not worried about that at all, once again, could have a storm. i think they will be done by 7:00, a shower possible at 88 degrees, going down there, maybe take the poncho, umbrellas just in case. 84 by the seventh inning, 81 by the also out. same thing for the skins game, think on the dry side the most

part. satellite and radar together showers there, widen out there, one storm toward the great lakes and then we have this boundly, it is a cold front that's going to come down tomorrow, as it does, it's going to bring us a chance of showers and thunderstorms, here we are at 1 in the afternoon, notice the storms and the direction they are coming from, from the northeast here, see a few more of those during the afternoon, on into the evening hours. plans tomorrow evening, maybe to go to dinner, i think you're okay there, may need to take the umbrella with you in case. high temperatures tomorrow, not quite as hot, quite as warm. 90, d.c., 91, fredericksburg, 85, annapolis with the scattered showers and thunderstorms. weather outlook tomorrow, looking good for the bike ride, lunch and recess, hot and humid, careful once again, maybe the umbrella will be necessary, most of the day looks dry. look at the weekend, a beautiful weekend here, 84 on your saturday, 86 on sunday. labor day looking good as well, a high temperature around 89 on that labor day. so the labor day weekend looks greeted, no matter where you're

breaking news now at 5:30, metro has just announced the resignation of chief safety officer, james doherty, been with lamotta five years and leaves with metro facing more scrutiny than ever. >> news4's transportation reporter, adam tuss, has been following this story all day. he joins us now on the phone. adam, how significant is this? >> very significant, wendy, when you consider that this is the top safety official at metro and of course, they have been dealing with this scandal for weeks now and it really all came to a head at a metro board meeting today. the metro board was as feisty as i have ever seen them, going after top metro staff officials. they went after the rail chief.

they went after jim doherty who has resigned today. they basically called jim doherty's office a paper tiger, meaning that, yeah, looks all good on paper and you might be able to enforce some things on paper but you really have no teeth. metro even conceded today that it needed to do a better job in a number of areas and the big thing that we learned today was that a safety official simply deleted the information that told metro about the tracks in question, about the derailment spot. simply, they equated it to deleting an e-mail that you might get, something of that significance. so, clearly, the board not happy with the safety department and today, this resignation. >> so adam, should we expect more departures down the pike? >> you know, jim, this could be the start of something much bigger at metro, frankly. there are a number of people who have been under the microscope, including mr. doherty for the last couple of weeks. i'm told by inside sources that

certainly, more people could be leaving metro. right now, that is not the case. it doesn't seem like there will be any other high-profile firings or resignations today, although this is certainly a significant safety step. metro, to be honest, had to make this step, a change so that the public and the ride course have confidence and you had board members today telling the safety department they have no confidence in the safety department. so this is a big step. >> all right. adam tuss, talking about the resignation of metro's chief safety officer, james doherty. thank you, adam. >> thank you. also only on 4, we got our hands on the video which could be key in finding the man who terrorized a store in a guy yet montgomery county community. this was a pharmacy. it shows the man with a gun robbing this drugstore in clarksburg, the middle of the day. the search for the gunman forced several schools in that area to shelter in place. neighbors were told to stay inside. shomari stone is live with the

firsthand account from one of the pharmacy workers, including what the robber was looking for. shomari? >> reporter: wendy, the pharmacy owner decided to share this video with us to help police catch the suspect. right now, montgomery county police are searching for this suspect. now, several schools were on lockdown here. american business owners were concerned. and that man walked right into the clarksburg pharmacy behind me, leaving two employees scared. >> its seas are scary. >> reporter: this woman doesn't want to show her face on camera. she is a victim of an armed robbery at clarksburg pharmacy in maryland. >> very shocked. it's very nice area. so it's very weird to have somebody just come in and think they can do something like that. >> reporter: take a close look at this surveillance video from this morning. it shows a masked man dressed in a striped, blue, long-sleeved shirt, khaki shorts, tan shoes with a black backpack over his shoulder. he calmly walks into the farm circumstance pointing a gun at the woman and the pharmacist. he forces the two employees on

the ground and they put their hands up. he seems to know exactly what he is looking for as he searches shelves and drawers. >> i was scared. i was scared at first, i'm a lot more calm now that time has passed, but's very scary. you don't know what they are capable of. >> reporter: he stole a variety of medicine, including prescription painkillers, then he walks out. they hope someone reck needs the man then turns him into police. >> you don't want somebody like that on the streets, especially a nice area like this off a lot of families around here. >> reporter: now, coming up at 6:30, you will hear from a parent who describes how tense it was during the school lockdown. back to you, wendy. >> all right, shomari. friends of the lone survivor of that on-air ambush in virginia last week say that vicki gardner does not want this tragedy to define her or define their community. gardner was being interviewed on live tv when she was shot in the back. wdbj reporter, alison parker and her photographer, adam board, were killed. gardner wants a place for the

as we reported a short time ago, metro's top safety officer out, resigning in the wake of the train derailment near the smithsonian station. >> weeks after the incident that led to a nightmare commute, we have learned about a mistake that could have potentially prevented it. >> our transportation reporter, adam tuss, once again at metro headquarters, there all day as the board blasted those top metro leaders. >> reporter: i'm adam tuss at

metro headquarters where today, metro staff got an earful from metro's board of directors. the issue, of course, the derailment that happened in early august even though metro knew the tracks in that session by the smithsonian station were out of alignment in early july for more than a month. what we found out here today at metro headquarters was that an employee simply hit the wrong button and deleted critical track safety information that put people's lives at risk. trains with people on them continued to roll over the section of track simply because someone hit the wrong button. that's what metro staff today and they certainly got an earful from their board. where does the buck stop? >> i take full accountability for the incident. >> you have got next to no information about what goes on operationalism you say you fly at a high level, you don't even look at the sops, what's the point of having a safety department if you are not deeply embedded in thing or's

operations? >> in the organization, the training manuals -- >> okay york need to hear your response. >> reporter: metro says it is going to review its policies, especially for track walkers supposed to man labor day visually inspect those tracks. they said simply, our track inspection process has to get better. at metro headquarters, adam tuss, news4. we just learned a young child died in the district this afternoon and there is concern about the response after the call to 911. that call was placed on hill side road in southeast, east of the anacostia river. news4 has confirmed the child had to be put on it a fire truck because the nearest ambulance was seven miles away. there's no indication at this point that the transport played any role in the child's death but ambulance response times have been a big issue in the city and one the fire department has tried to address. we have several crews working this story. we will get back to it as we learn more. also now, coverage of the

top stories, including a deadly the and run in virginia. also, the search for a suspect in a bold heist that prompted a school lockdown. but first a message on social media sparks a dramatic chain of events, a community on edge, more police patrolling the streets and a young man is in custody, all because of something that was posted on twitter. news4's chris gordon is in charles county to tell us why police took the threat so seriously. >> reporter: the threat put some people who live in la plata into a panic. >> you know, it's shameful that somebody can -- so many people like that. >> reporter: the tweet says -- police say some people didn't go out to shopping centers last night as word of the threat spread. >> people were scared. people staying home, they were scared. not going out shopping? >> not going out shopping.
