region. prince william county police officer ashley guindon, virginia trooper chad dermyer. three deaths in the past four weeks taking a toll on our area's law enforcement. >> these are men and women that are not only peace officers and protectors, they're also in the community. they're football coaches, basketball coaches. >> reporter: for trooper michael mcsellers, fellow trooper chad dermyer's passing personal. >> chad was married to his wife 15 years. i'm married to my wife 15 years. he has a son and a daughter. i have a son and a daughter. it seems like every time i take this thing off, i'm putting it right back on. >> reporter: his 12-year-old son even asking him to reconsider his job. >> if everybody decides to stop doing this job, then what? we're in trouble. we give in,

everybody loses. >> reporter: helping motivate him and his colleagues to press forward, every day residents, simple actions. >> i had a co-worker who had someone put a note on their car and say, we're praying for you. man, just think. i'm getting chills as i think about that. it's so empowering. >> the law enforcement community gathering right now in virginia's capitol tonight, richmond. the vigil expected to draw hundreds. it's been moved to vcu's segal center. >> david culver reporting. thank you. a search under way tonight in alexandria for the person responsible for the city's first homicide of the year. a man was beaten tuesday on south alfred street in old town. he died today. news4's jackie bensen is near the scene gathering more details. >> reporter: doreen, he was so close to home, so close to home when this happened. take a look down the street. just past where those ladies are walking is where

malaku abraha was walking. police found him, he was on the sidewalk, he was conscious but obviously injured and taken to the hospital where we are told this afternoon that he did not survive those injuries. now, police believe those injuries were sustained as the result of a robbery. they are right now trying to find some people who know something about this who saw this gentleman. he's 69 years old, lived here in this neighborhood walking down the street tuesday night about 9:30. very close to a busy restaurant area. a lovely neighborhood where people are often out walking at night. someone who saw the person who came up to this man who tried to rob him who injured him to the point where, as i said, he did not survive his injuries. live in alexandria, jackie bensen, news4. >> jackie, thank you. the newspaper vendor accused of stabbing a man at the addison road metro station is behind bars tonight. police arrestedda

in the badger state today after a week filled with high-profile stumbles. if the latest polls are right, ted cruz is heading for a key victory on tuesday, and anti-trump republicans will be one step closer to their goal, an open convention in july. >> what we cannot do is turn off wide swaths of the e lack for rat, women, hispanics, african-americans and that's what donald trump will do. >> reporter: cruz and john kasich are sharpening their attacks on each other. >> if ted cruz's mouth is moving, he's lying. >> and while kasich denounced that super pac ad, he offered his most pointed critique yet. >> the problem with senator cruz is he has no record. his record is shutting down the government and making everybody he works with upset. >> reporter: on the democratic side, an upset is something hillary clinton cannot afford in home state new york where she is far ahead in the polls. but bernie sanders holds the lead in wisconsin, a

that's giving new hope to underdogs from both parties. and if trump does end up losing down the road in an open convention, it's likely we'll look back to this week as a turning point. aaron? >> brian mooar live for us. brian, thank you. if you had plans to visit the washington monument this weekend, change them. it's now shut down for the second time this week after another elevator breakdown. this time it got stuck 490 feet up, just below the observation deck after it let some people off there. 86 people had to -- were at the top and had to walk down nearly 900 steps. the monument will be closed all day tomorrow for repairs. this is at least the tenth time it's been closed because of elevator issues since may of last year. >> medstar is getting back online after the hospital system's computers were hacked this week. they are about 90% back to normal. monday's attack affected all ten of the hospitals in d.c. and maryland as well as 250 clinics. doctors and nurses used

records. staffers were locked out of their e-mail accounts and patients could not make appointments. no patient information was compromised though. >> now to the weather. it appears there's something for everybody in the forecast this weekend. >> yeah. rain, wind, sun. maybe even a little snow. what? amelia segal is tracking it all from the storm team4 weather center. amelia, it is april, you know. >> i know. and it's no april fool's joke. we're talking about the chance for some rain and wet snow showers saturday night. especially north and west of town where we could see some of the wet flakes falling. absolutely no accumulation. right now tracking some isolated rain on storm team4 radar. this in fauquier county moving to the east-northeast into parts of prince william county and heavier cell now just to the east of the luray area as well. we'll continue to keep a close eye on this. this activity should be out of here by about 8:00 this evening as a cold front moves through the area. but we could still see some high winds and heavy rain in those cells, maybe some small hail.

temperatures. 80 right now. our high today was 82. first time we've hit 80 since early november. by 9:00 no worries of rain. the temperature around 66. by sunday we'll be talking about temperatures that feel like they're in the 20s. i'll be trabing this major temperature cooldown coming up. >> thanks, amelia. president obama told world leaders that it will be catastrophic if isis obtains nuclear material. that warning came at the nuclear security summit here in washington. president obama noted the terrorist who bombed the brussels airport were tracking and recording the movements of a top belgian nuclear scientist and the president said isis has already used chemical weapons in syria and iraq. >> there is no doubt that if these mad men ever got their hands on a nuclear bomb or nuclear material, they most certainly would use it to kill as many innocent people as possible. >> 50 world leaders have been meeting here in washington for a it

safeguard atomic materials to prevent nuclear terrorism. new concerns about security over a new muslim center in prince george's county. that $110 million facility is located off good luck road in lanham. counsel at the bureau chief tracee wilkins is joining us with reaction from neighbors. >> reporter: the president of turkey is going to be here, chris, along with muslim dignitaries from around the world. of course security is a concern. the center in prince george's county is the largest muslim center in america. you are instantly transported as soon as you walk on campus. >> i have never been to turkey, but everybody that has been there say that this is just like being there. >> reporter: the center goes three stories underground and includes an indoor pool, basketball court, fitness center and then there's the incredible beauty of what's above ground. >> we have a mosque, a fellowship

be a four-star restaurant and a turkish bath. >> reporter: the $110 million facility was built by the turkish government. tomorrow will be its official grand opening although it's been operating since april of last year. given the tension in the world and the violent acts of extremists, even some people who live near the center are worried about security. >> i'm afraid they may be victimized rather than anything else, and in today's society that is highly likely, and that's a shame. >> reporter: it's something organizers here have pondered as well. >> i hope there will not be any problem. we try to move on faith and faiths alone. >> reporter: tomorrow the president of turkey will join international dignitaries as well as state and local officials for the grand opening. all attendees must have security clearance. >> the prince george's county police officers have been working with us for the last few months. >> reporter: turkey's secret service is also here. the hope is all will go well as the center is striving to be a gathering placeor

all faiths. >> we have to increase tolera e tolerance. if we can do it with just our little efforts, it can become contagious. >> reporter: county executive rushern baker will be among the dignitaries here tomorrow. his office saying they are very proud of how smoothly things have gone since the center has opened. things get under way in the morning and, again, you do need a security clearance to attend tomorrow, but outside of that, the center is open to the public and they do tours here. it's a fascinating facility. reporting live in lanham, i'm tracee wilkins. back to you in the studio. >> thank you. next, her murder dominated headlines. tonight new reaction from chandra levy's mother. how she's using art to help her heal as she prepares for her daughter's accused killer to get a new trial. fighting the zika virus. how these brain scans are offering new insight into its effect on unborn children. a secret service officer saved three lives in less than two years. coming up, an emotional reunion between that officer and

"meet the press" moder c

year. we start where we started last week and probably the week before that, donald trump. he's had a particularly bumpy ride this week. >> he has. he's had bad weeks before and he usually fixes them by simply winning, going and winning a primary or winning multiple primaries on a tuesday and suddenly it heals all of those wounds. this one feels different. this one feels as if this was an accumulation of a lot of bad baggage is probably the best way to describe it, and it ends up happening where he also punctuates this with a loss on tuesday night, then all of a sudden i think it's one of those, boy this, could suddenly snowball because we have two weeks before there's another primary. it takes a long time for him to recover and the stop trump movement could then feel as if we actually can beat this guy, and they stiffen their spine. you know, there's some folks waffling going, well, fine, i'll stop fighting this, but if he loses, they won't stop fighting.

effort toward unit. trump met with the rnc leadership. what have you learned about that meeting with reince priebus. >> you want to know what most of it was about? it was donald trump trying to learn the process. he doesn't understand how the delegate selection prove scess works. actually selecting the individuals. he's obviously upset that, for instance, louisiana has been a big example that people have heard about. louisiana held a primary on super tuesday -- excuse me, it was a little after super tuesday. trump won it, cruz has more delegates because cruz went down to the state's convention and he was able to turn the rubio delegates in his delegates and there were some uncommitted and he ended up with more delegates than trump did. trump essentially was asking these questions and it turned a little bit into a tutorial and this is what a lot of us thought was going to be a problem for trump at some point. it took a lot longer for trump to discover it which is he doesn't have the team in place ready to do this yet. >> surprisingly.

moment if we can. hillary clinton has been going back and forth this week. she was in wisconsin and then she bailed and went to new york and now she's back to wisconsin. what's all that about? >> the clinton campaign almost sees the two states connected. they may very well lose wisconsin and they're prepared for it. they don't want to get blown out in wisconsin. they don't want to give up and have sanders' 3-point win and turn into a 20-point win. if he wins big in wisconsin, the next up is new york. he gets momentum out of wisconsin and maybe he pulls an upset in new york. she's got a delegate lead that is almost insurmountable. boy, she can't afford to continue to have sanders gain momentum again. he's outraised her -- >> gain momentum and gaining funds too. >> he keeps raising a ton of money. yes, she has more delegates, a lot more delegates in some cases but a big win for him in wisconsin, then suddenly that could give him momentum going

clinton campaign is now going back to wisconsin hoping they can keep it close and tamp down anything he gets out thereof. >> before you go, world leaders in town for the summit at the convention center. any takeaways from that? >> well, it was going to be totally overshadowed by the presidential campaign but in some ways it didn't because trump talked about sort of his loose talk about how he would handle nukes. i think in many ways it made this summit more relevant, made people pay more attention and it may mean it will live beyond. president obama created this summit. will it live beyond the obama years? perhaps because of what happened this week it will. >> all right. >> all right. more to come this weekend, chuck. >> we'll see you sunday. >> we'll have all the latest political news sunday morning at 10:30 on "meet the press" here on nbc 4. thank you. now to the terror attacks in brussels. funerals were held together in the netherlands for two dutch siblings killed in the airport coming. alexander and sasha were returning to their home in new york when thbo

alex was actually on the phone with his mother during the blast. the line went dead when that bomb went off. saving someone from the brink of death is rare, but one secret service officer nominated for homeland security's highest service award has done it three times. news4's meagan fitzgerald has her story and the touching message from one of the families she helped. >> reporter: not much is prodistrictable for secret service officers. just ask codie hughes. she's been securing the white house and interacting with the public for six years. >> every day is a new day so there can be different scenarios that happen every day. >> reporter: over the last 18 months there have been three scenarios where hughes snapped into action to save the lives of complete strangers. one man collapsed in leesburg and a few months later she revived a homeless man lying on a park bench in lafayette park, but the first incident was in the east wing of the white house in august of 2014. >> it was a

collapse and was turning blue. so my medical instincts kicked in. >> reporter: that man is jack torres who is also a mayor in new mexico. he had a heart attack in the hallway and briefly died. >> to me i'm thankful that this individual has -- can continue with his life. >> reporter: and the mayor's son, carlos, is thankful too. >> i'm carlos torres. >> hi, how are you? >> good. how are you? >> good. >> carlos was also there and for the first time since he's able to personally thank his hero. >> i'm so glad he's doing good. >> carlos' family has gone on to celebrate so many moments since then. >> it's good seeing you. >> you too. >> reporter: all thanks to an officer who goes above and beyond because she cares. >> i like helping people. if i see something isn't right i will go and assist to see if everything is okay. >> reporter: next week hughes will be royced by the town of leesburg.

last question. when i asked her how she hopes this long ordeal will end. >> i don't think it's ever going to end. i think that one day -- because i'm not that young. i'm going to meet chandra in spirit again. and that there's no separation in death for any of us. >> the exhibit featuring susan levy and other artists opens tonight. it will run through april 28th. >> you can see it at the artists and makers studio in rockville. still ahead tonight a tribute to a late supreme court justice. the multimillion dollar effort to rename a local law school after justice antonin scalia. narcan is a life-saving medicine for those suffering from heroin and opioid overdoses but one northern virginia activist has the board of pharmacy is blocking her efforts to dispense the drug even as some pharmaciesre

a plan to rename a local law school after justice antonin scalia is causing controversy. george mason university just received $30 million in gifts for its law school. $20 million came from an anonymous donor who requested that the school be named after justice scalia who died last month. the board approved the name change, but critics say justice scalia was a polarizing figure and it's too soon to know what kind of legacy he will leave. >> that's not really the kind of reputation you want your law school to have. that's not a great way to attract a diverse student body and get a lot of people from all over the country to come. >> no matter -- however you view justice scalia as a pers

the legal world, and i think naming the school after him is a great way to recognize intellectual significance and a lasting legacy. >> delegate simon has started a petition against the name change. he plans to take it to the state council on higher education which has the final say in the matter. starting today it will be easier for virginia and maryland residents to get a life-saving medication called narcan. it can reverse the deadly effects of an overdose from heroin or other opiates but as julie kari repocar carey report been a setback when it comes to who can dispense the drug. >> reporter: after since last summer when narcan became available without a prescription, jenny atwood has trained hundreds of worried parents, health care workers, even drug abusers themselves in how to use the life-saving antidote. >> all you do after that is you spr

>> one of the most frightening things in the world. >> reporter: two weeks ago this loudoun county mom who nearly lost her son to an overdose got training and a supply of narcan from atwood. >> and at peace of mind, priceless. >> reporter: but atwood can no longer provide narcan to those in her classes. last week the virginia board of pharmacy told her to stop saying this legislation only permits pharmacists and law enforcement to distribute narcan. >> this is coming down to an interpretation of the law. the pharmacist and the doctor said virginia law allows for trainers to dispense. >> reporter: atwood lost her brother to an overdose and began the chris at wood foundation. it raised the funds to pay for and provide narcan to those in her classes. >> this is a life-saving medication and when people need a life-saving mag, they need it now, not two weeks from now.

appealing to the attorney general's office to see if the rules could be reinterpreted or altered. in the meantime though, getting narcan from cvs stores just got easier. maryland and virginia just joined 21 other states where cvs provides narcan without a prescription. much like getting some cold medicine, it is still kept behind the counter. in loudoun county, julie carey, news4. next a local physician sheds light on how the zika virus develops and its affect on unborn babies. and up in smoke. details behind the mass protest that could lead to mass arrests outside the white house

they say character is what you do when no one is watching. david trone banned the box so people who've paid their debt to society could have a chance. and fought so hard for criminal justice reform, they named a center after him. and because education was his way out david offered it free to employees. and over 14 years ago began offering them partner benefits. evening the playing field has always been david's mission. in congress it'll be his job. it's not how you run, it's how you live. i'm david trone and i approve this message.

medical experts and government leaders from all over the country convened today at the centers for disease control in atlanta trying to learn the latest on the zika virus which is updating every day. a zika virus case from our area revealed some new information just two days ago. i learned more about it today from the local physician who worked with that patient. >> so this is our patient over here and this is a normal baby at the same gestational age. >> reporter: these scans show the brain development of a fetus at 19 weeks. this mother was pregnant when she travelled to central america last fall. she developed a rash and other symptoms when she returned home to the d.c. area. she tested positive for zika and then eventually saw dr. rita drigers, a maternal fetal medicine specialist. >> back in november and as you recall back in november zika wasn't what zika is now where we're hearing about it on a

>> reporter: the doctor shared two important things to know about this case. the fetus appeared to be developing normally for almost two months after the mother was exposed to zika. up until 4 1/2 months things seemed okay. >> correct. >> reporter: at five months it was clear that -- >> things were not okay. ultrasounds at that point had been reassuring in that the measurement of the head were normal and there were no calcifications. so she was reassured at that point. >> reporter: the doctor said the abnormal brain development was very clear at 19 weeks. follow-up tests confirmed that and the presence of the zika virus in the baby's brain. and, too, the mother tested positive for the zika virus until more than a week after the pregnancy was terminated, much longer than the known life span of the virus, 11 days about. >> in our case our patient continued to test positive right up through the time that she

was nine weeks after she became symptomatic. so for a full nine weeks she continued to have the virus in her blood. >> reporter: it's possible the fetus was replicating the virus. both of the parents are now virus-free. this was a very tough case for dr. drigers and certainly for the couple who had been hoping to have a baby. but it's also providing really valuable new information to researchers trying to understand how the zika virus works. >> so we know some time line now to recommend. if somebody comes in four weeks after their symptoms and has a normal ultrasound, we don't know that that's reassuring because it takes time for the virus to have effect on the fetus. still, this case is raising new questions about zika virus and pregnancy. for example, how long should that couple wait before they try for another pregnancy? and what do ob/gyns across the country tell other women about their plans for a safer pregnancy? the experts are racing to find some answers. anyone heading to the
