charleston, virginia that had been painted black. the court documents indicate maryland live security staff were able to use that casino's surveillance system to identify four people from northern virginia. investigators believe the four netted thousands over several day, including $4,000 in just one day by gambling with and cashing in the phony poker chips. search warrants served last week in fairfax county, including at this home in annandale reveal investigators were looking for casino-style poker chips. the scheme was uncovered four days before a multimillion-dollar chip counterfeit discovery at the borgata hotel. the two incidents are not connected. does it surprise someone that someone would try to gamble with bogus chips? >> really, okay. is there a reason they would want to use fake chips? >> well, it's maryland. nothing surprises me. >> reporter: a spokesperson for maryland state police would say only that the matter is under active investigation. so far no arrests have been made. jackie bensen, news4.

it ended up on the side of the truck. little falls road is narrow, and cars are parked on both sides. >> it strikes a chord for me. it's upsetting. >> reporter: carl drives on the road. he says some people drive fast through the speed zone. >> definitely bumps or something to tell people to slow down you. never know what can happen here. i've seen it the busy times are at the end of school. and is there a lot of people walking back and forth. so there needs to be something to slow people down a little bit. >> reporter: the dump truck driver stayed on the scene, and police say he is cooperating with the investigation. he hasn't been charged. >> some of those people just blow right past. they don't care that it's a school. they don't care that people are walking. >> reporter: now, this crash is still under investigation. police have not determined if speed was a factor. live in arlington, i'm shomari stone, news4. closing arguments are expected tomorrow in the trial of a former sunday school teacher accused in a deadly road rage incident in fairfax. surveillance video shows lee

sena's confrontation with william o'brien in a parking lot last april. sena admitted to following o'brien there because o'brien had been honking his horn at him. sena punched the 63-year-old who died ten days later from blunt force trauma to the head. during an interrogation, sena said o'brien threw the first punch. tonight police are hoping a key witness will come forward after a deadly shooting in woodbridge over the weekend. three men stormed into a grocery jewelry store on friday night and killed the cashier. the victim 21-year-old glenda marisol cocoromera. she moved here from el salvador and just had a baby girl. detectives were able to talk to a customer who was able to hide under the counter during the shooting. the gunman did not make off with any money. tonight there are new concerns about slow response times from d.c. firefighters and emergency dispatchers. this after several high profile cases. wendy reiger is at our live desk with more.

wendy? >> reporter: well, in testimony that lasted into this evening, families blasted d.c. fire and ems, saying their relatives would still be alive if the paramedics had just done their job. medric mills' son had tough words for the d.c. council. >> what happened to my father is unacceptable on any level. procedurally, morally, or legally. these blunders by the fire department have been going on for years. they've proven that they are unable to address their shortcomings internally. >> medric mills died last month after he collapsed outside a d.c. firehouse. the district's own internal investigation found that five firefighters inside knew that he was collapsed and in need, but they failed to take action. deputy mayor says this shows a disregard for human life, but it is not a system-wide response problem. in another case just this past friday, sources are telling news4 that a toddler went to the

hospital by fire truck. he was having seizures, and the closest ambulance was seven miles away during rush hour. critics complain there just aren't enough ambulances on the d.c. streets. add that to another problem, or other problems that occurred last year on d.c. ambulance response times. in january of 2013, a man died after he waited 30 minutes for help to arrive in southeast. two months later, a police officer waited almost 20 minutes after he was injured in a hit-and-run. prince george's county crews got him to the hospital. days later, a stroke victim also went to the hospital on a fire truck because the ambulance was delayed. at the live desk, i'm wendy reiger, back to you. >> thanks, wendy. tonight a battle over bike lanes picking up speed in alexandria. there are plans to transform part of king street into an area that is safer for bikers. but it will come at a cost. erika gonzalez joins us live with the growing backlash.

erika? >> reporter: i hey, doreen. when you think of king street you think of a pretty expansive piece of roadway. but what we're talking about zeros in on a few blocks. reaction is mixed, to say the least. >> we don't think this is the best decision. >> reporter: up for review tonight in alexandria, the decision to remove parking along king street in order to add bike lanes. >> every day i ride king street. >> reporter: and the difference in residents' opinions is very clear. >> if you go up and down the strip, all you're seeing is anti-biking signs. >> we're not anti-bike. we just think it's not a safe plan. >> reporter: if the city approves, the area directly impacted would be between west cedar and highland place. the plan adds four and five-foot bike lanes in either direction, but narrows lanes by one foot. aaron eastman asks what about emergency vehicles on that road? >> if the vehicle is 10 1/2 feet

wide and the lane is 10 1/2 feet wide, it's an accident waiting to happen. >> reporter: a cyclist all his life, he says with or without the lane, it doesn't change the route to welcome, it's the best we can get, honestly. it's a bike lane. i'll take it. >> reporter: this will now go before the city council next month. live in alexandria tonight, erika gonzalez, news4. >> thanks, erika. an historic collaboration tonight between maryland's largest immigrants right group and the nation's largest civil rights organization. the naacp's maryland state conference rallied in indianapolis to focus on challenges facing minorities. they called on lawmakers to address issues such as minimum wage, foreclosures, immigration, and funding for historically black colleges and universities. congress could be the next battlefield over the pentagon's newly proposed drastic military cutbacks. some lawmakers are already

objecting to the 2015 budget laid out today which would slash the size of the active duty army down to 440,000 soldiers, the lowest level since before world war ii. air force aircraft would be retired. some bases would be closed. and while most service members would get small raises, some housing and health care for military families would be cut. federal workers will be getting another race. the white house announced this afternoon that president obama will propose a 1% raise for federalorkers for the year 2015. government employees have gone three straight years with pay freezes before they got a 1% raise this year. next and new at 11:00, this isn't the family photo op they planned on. tonight their new demands after a dramatic deck collapse was caught on camera. and perhaps a prescription for error. these machines are supposed to eliminate mistakes. but some problems are still getting multiplied. the news4 i-team investigates.

a rare moment in midair. the scare for a pilot and what happened next.

some new video is part of the evidence in a lawsuit after this deck collapsed beneath a family. security cameras recorded the accident. it happened in new albany, indiana just a few days before christmas. small children and a baby are in that crowd that fell 15 feet. several people were injured. some of them are still

recovering. a woman was hosting her family at a neighborhood clubhouse for the holidays. she is now suing the companies that built and maintained that deck. now to a major story regarding women's health. a new recommendation that could save lives if they have the brca1 breast cancer gene. a study out of canada says women with that gene mutation can reduce their risk of ovarian cancer by 80% if they have their ovaries removed by age 35. that can be a difficult decision for many women. they go into immediate menopause and can't conceive children. having their ovaries removed can also reduce the risk of breast cancer since it decreases hormone levels. cutting edge technology that is supposed to keep you safe. but tonight the news4 i-team worry why what they call pharmacy robots could make medication mistakes even worse. tisha thompson has our report.

>> reporter: next time you go to your pharmacy, peek around the counter. you might see a large machine tucked behind a shelf that is a pharmacy robot. it's supposed to make medicine safer. but the news4 i-team is going to show you how these machines can multiply one mistake into dozens. >> they provide a valuable service. >> reporter: carmen is the executive director of the national association of boards of pharmacy and says more and more large chains are using pharmacy robots. >> the robot holds your top 200 fastest moving tablets and capsules. >> reporter: in this video from a prom meant robot maker you can see how a pharmacist types a prescription in. a robotic arm pulls pills from a cell, place them in a bottle and labels it. >> each robot comes standard with an open control center. >> they can help with dispensing. and the error rate is significantly lower than if you have technicians or even pharmacists sometimes filling prescriptions. >> reporter: dr. sydney wolf at the watchdog public citizen says

there have been two respected medical studies that robots do cut down on medication errors, but only if humans load them properly. >> a human being has to fill the machine with various kinds of medicines. and they could make a mistake. and if they make a mistake, even the machine dispenses what is told to, so to speak, it may have been told to do the wrong things. >> the mistakes, though, that were being made a really human error. >> reporter: this pharmacist worked in a national chain that used this type of robot. when it was installed, he said his company also upped the number of prescriptions his store was expected to fill, to as many as 900 a day, forcing his staff to rush. >> say you ran out, you got cheated. ran over, put the bottle from the stock area. >> reporter: but then it happened. an employee put 250 milligrams of an antibiotic into a cell already partially loaded with

500 milligram pills. >> somebody had inadvertently grabbed the wrong bottle. so as a result we were dispensing 500 milligram amoxicillin with 250. it's not a big deal, you think. but if the patient is sick and didn't get well and needed to see the doctor again, or needed another prescription, it becomes a problem. >> reporter: some mistakes involve dosage. others mixing up different drugs. in marijuana, the attorney general found a robot gave as many of 50 children a breast cancer drug instead of fluoride tablets. after the publicity surrounding that event, zorek says his company instituted a system aimed at preventing robot mistakes. but says you may never know you got the wrong medicine because the pharmacy may never catch the mistake if a robot was involved. >> there had to be at least 47 to 60 prescriptions that were filled for this antibiotic. now, were they misfilled? we don't know. >> all the experts say you

should not be afraid of pharmacies using robots to fill your prescription. but you should always double-check your prescription by looking up what the drug looks like and comparing it to what's in your bottle. if you think there might be a problem, call your doctor. tisha thompson, news4 i-team. >> and to hear more from pharmacists about what goes on behind the counter, we invite you to log on to our website at nbcwashington.com, and then click on investigations. doug is back with more about our weather and the colder air moving in and snow too? >> so much colder. we'rgoing to get a lot of cold and a little bit of snow. >> okay. >> and we're going to get two doses of it, and maybe really three or four of a little bit of snow. let's take a look and show you what is going on out there right now as temperatures have fallen. the winds have calmed down, at least a little bit across the region. you can see the flag not moving too much. still a wind out at the airport at about 6 miles per hour. that puts our windchill down to about 30 with the actual temperature around 35. notice the rest of the numbers

around the region. they're in the upper 20s already. 28 in gaithersburg. 30 in culpeper. and right now huntingtown 28 degrees. so a very cold gh for sure. and that means anything that falls from the sky will be snow. storm team 4 radar showing we are all clear right now. but back to the west, this is what we're look at. the snow making its way down. once again, this is a very, very small system. and there is not a single advisory. no winter storm watch or warning with this. this is just too small of a system. you can see the snow around omaha, making its way right on down towards our area. and it should be able to get here by this time tomorrow morning. now, let's take a look at it and future weather, 11:00 tonight, we're on the chilly side. we're going to stay that way through tomorrow. around 9:00, notice area wide snow from d.c. up through frederick and leesburg and winchester. maybe a half an inch. we're not expecting much from this. it could make some roadways a little slick, especially the secondary roads. 5:00 in the afternoon, most of it is out of here. we're just going get on the

chilly side. tomorrow a very cold night. the snow will try to return on wednesday morning, just a little bit in the way of light snow. wednesday i would not be surprised to see some accumulating snow, maybe half an inch to an inch. but not too much. what to expect? light snowshowers. best chance 10:00 a.m. to three income the afternoon. minor accumulation at best is what we're talking about. just enough to cover your outdoor deck, things like that. 36 degrees on your tuesday. 32 on wednesday. let's talk a little bit more about that wednesday storm. snow is here early in the morning. and we will see that little accumulation. half an inch to an inch, that could be enough to cause some delays, maybe a two-hour delay here and there. i'm not expect anything cool closing, however. 40 degrees on thursday with sunshine. probably the nicest day of the week. and then we get really cold. 30 on friday for a high. most of you will stay in the 20s. saturday, another chance for some light snow. kind of similar of what we're going to see the next couple days. minor accumulation with a high of 42. that would be late in the day. on sunday, we get to 31 degrees for a high.

staying below freezing once again, even next monday. yeah, another chance of some rain or snow coming in. that temperature around 36 degrees. we've got a lot of winter left this week, maybe even some of next week too. i don't see another warm-up like we had over the weekend, coming for at least maybe two weeks. >> you better have some hot tea, because this could be long week for you. >> this is cold water. >> thanks, doug. >> put a little bourbon in there too. >> we've got sports coming up. a wild finish for the terps and thei

this is the xfinity sports desk, brought to you by xfinity. your home for the most live sports. >> we got to assume that syracuse didn't come into maryland thinking it was going to be easy, because it certainly was not, was it? >> no, not at all. whenever that place is packed and the fans are into it, you know that this team is going to be up. they're going to play well. that's what they did. but they fell a little short against syracuse. maryland had a little extra time to prepare. tonight they gave them all they could handle. the game went down to the wire, but still the terps came up just a bit short against the fourth-ranked team in the country. maryland students a little flash mop here before the game. they were fired up all game long. luckily, the ending, as good as this flash mob. second half, maryland down four. cj fayer with a three-pointer

right there. he had 17 points. the orange up seven. the terps did answer. that's seth allen, a three-pointer of his own. he had 22 points. maryland is back within four. under 15 seconds left. terps down one. nick gets to the rim. no call here by the officials. a lot of contact there. coach turgeon not happy about that. last chance for maryland. this is allen heating up a three. just off the mark. can't get it to go. the terps, they lose 57-55. after the game, turgeon still not thrilled about that no call on nick faust. >> i thought nick got fouled. and i think the replay showed that. >> they shot 27 free throws. if anybody is going to complain about the officiating, i'm going to complain. >> didn't call it. and they win the game. >> five times that we saw them going to the basket that there was no foul, and there was a foul called. five times.

so you want to talk about one play? i'll talk about five times. >> jim boeheim, syracuse head coach. still probably upset about that duke game. that's funny. the terps have three more regular season games remaining. their next one comes against clemson. all right. over in baseball, every year in spring training, players work on different aspects of their game. dianna russini is in florida with what catcher wilson ramos is hoping to accomplish this season. >> reporter: the nets starting rotation could be one of the best in the league there is a lot of pressure on them to perform this season. but how about the guy behind the plate? wilson ramos. he says he has a very big challenge ahead. >> i've been living my life. i've been living right now. and last year, you know, we get really good pitching staff. but we need to be together. but a offense and defense together. right now i saw those guys

throwing during the live and i like what we got. >> reporter: ramos believes the only way he can be successful this season is if he stays healthy. he says the only way he can prevent himself from getting injured is to make sure he not only eats healthy, but is working out as often as possible. dianna russini, news4 sports. >> all right. the nationals first spring training game is this friday against the nets. >> no sleeves on.

we're still tracking the silver line metro problems we first told you about on friday. and now we know major construction issues are going to delay its opening again. officials with the dulles metro project say the problems include water leaks along the line, automated train control problems, and missing construction permits. it's not clear when the line will be able to open, but these problems are expected to push the project back at least another month. heart-stopping moments for a pilot in florida, and it was all caught on video. the pilot was a few miles from landing in ft. myers when a bird suddenly slammed right into the windshield. glass flies, and heavy winds are whipping the plane, flying at 170 miles per hour. it sends it into a quick shake, but the pilot was able to keep steady hands. the pilot suffered a cut to his head and quite a shock, but

still managed to land the plane safely. great news for weight conscious here. taco bell is launching a breakfast menu that features something called the waffle taco. >> oh, gosh. >> it's a waffle rapped around -- there it is, bacon or a sausage patty with scrambled eggs, cheese, and syrup on the side. let me say that again. a waffle wrapped around bacon or sausage patty with scrambled eggs, cheese and syrup on the side. taco bell says it's trying to appeal to its fan base of younger men. >> okay. >> eat those all the time. >> is that right? >> i ♪ [ cheers and applause ] >> steve: from studio 6b in rockefeller center, in the heart of new york city. it's the "tonight show" starring jimmy fallon. tonight join jimmy and his guests -- reese witherspoon fred armisen,
