Authorities have not revealed a cause of death, but a Police Affidavit released today alleges the suspect pulled out what appeared to be a shiny rigid object and followed weiser. What do you think is the motive mere . You know what, its hard to know. Reporter Police Say Austin firefighters provided a crucial tip after seeing this Surveillance Video released thursday of a person of interest walking with a bike shortly after weiser disappeared sunday night. They remembered that on monday a woman had seen criner lighting a fire in an abandoned building. When firefighters arrived, police took criner to the shelter for homeless youth. Once police connected the dots thats where police found him. The common denominator for our youth is they have been through situations and sometimes lifetime of trauma. Reporter according to a High School Magazine profile in texarkana, tecumseh, he had a troubled child hood in and out of foster care. He was under the agencys care and had just run away. The agency said he did not know where he was until after Police Brought him to the homeless shelter. Today on the ut campus, relief and sadness. Its been a nightmare.

Lets turn now to the panic take at lackland air base in san antonio. Reports of an active shooter as the base was flooded with first responders. Two people are dead, and authorities are calling it a deadly incident of workplace violence. Nbcs Kerry Sanders with late details there. Reporter this time it was Lackland Air Force base on lockdown, 8 40 this morning, military and civilian, running for safety when the prerecorded alert was broadcast. Military police and bexar county deputies brought to the scene and on this huge base popular 82,000 where kids also go to school immediate fairs of a terrorist attack. The first thing that comes into mind terrorism, you know. Everything thats going on in the world. Its not safe these days, its not. Reporter shot and killed today, two americans an officer and an airmen, but it would take hours before investigators figured out it was a murdersuicide. Our initial assessment is that this is not an act of terrorism. Reporter training forever an active shooter is now a fact of life on military bases. As a result of that training, we were on scene and we were in the facility within three minutes of that initial call. Reporter even with training videos produced by the air force, active shooting situations become panicked moments. I was scared. I mean, its very close to home. Its literally, you know, a bloc away. Reporter tonight on base at lackland a question. How did anyone get two loaded pistols on base when the only people allowed to carry are military police . Kerry sanders, nbc news, miami. He was most wanted, an alleged participant in the terrorist attacks taken down today in a series of raids caught on video. The big question this evening is he also the suspect known as the man in the hat seen just before the airport suicide bombing in brussels, belgium. We get more tonight from nbcs bill neely. Reporter dramatic daytime arrests on brussels streets today. Five in all, two of them isis suspects wanted for mass murder. Mohammed abrini is the last known suspect from the paris massacres. He was arrested in a brussels suburb after five months as one of europes most wanted, renting rooms for killers. Some of the suicide bombers stated in this rented flat just before the attacks in paris. Reporter but he may be tied to a second atrocity. Investigators saying they are trying to prove if this is abrini, the man in the hat with two suicide bombers at brussels airport. Just yesterday Police Released these new pictures of him walking away from the bombing, and they asked for help to find him. I think abrini is very important, connects the brussels attacks and paris attacks and dna all over the paris attacks. Reporter police are still searching the area which isnt far from the isis bomb factory where mohammed abrynys dna was found. In november abryny was filmed at a gas station near paris two days before the killings. With his boyhood friend Salam Abdeslam who also fleld the attacks. Next day the two men were seen with a suicide bomber in a car used in the massacres. Police say they are breaking this deadly isis cell. Salam abdeslam will soon be sent for trial in paris. Now his accomplice, abrini, joins him behind bars. And investigators say one other man arrested today osama kay, brought the bags used in the airport bombings and may have been with the suicide bomber at the metro so they believe they bought two men at the very heart of the terror here. Lester . Bill neely in europe, thank you. Now to tempers flaring and strategies shifting tonight on the campaign trail here at home as pressure builds on both Hillary Clinton and Bernie Sanders to win new york, and on republican side donald trump is making moves hoping to avoid a contested convention as ted cruz proves a powerful force in the race for delegates. A lot to cover. We have it starting with nbcs Andrea Mitchell in washington. Andrea, very busy friday here. Indeed it was. Good evening, lester. Bernie sanders tonight telling a brooklyn crowd if they win in new york they could win the nomination, making it clear just how critical this new york showdown is for both sides. Hillary clinton not letting up on Bernie Sanders today. Seriously, ive been called a lot of things over the years, but unqualified has not been one of them. Reporter even as sanders visiting his old brooklyn neighborhood. I spent the first 18 years of my life in apartment 2c. Reporter spent much of the day trying to smooth things over. I respect Hillary Clinton. We were colleagues in the senate and on her worst day show would be an infinitely better president than either of the republican candidates. Shes qualified . Of course. Reporter and jane sanders with rachel maddow. He has said, okay, lets lets not use the word unqualified. Okay. Lets use the word contrast. Why do i think im better than her . Reporter some clinton supporters saw sexism in the comment. Calling Hillary Clinton not qualified is like fingernails on a blackboard for many women across the country. Reporter and bill clinton asked if that would happen to a man with the same resume. Of course it wouldnt. Reporter meanwhile, he was trying to clean up his own controversy after yelling at black lives matters hecklers protesting hillary for calling drug dealers super predators in the 90s. You are defending the people who kill the riots you say matter. Tell the trout. I almost want to apologize for it. I rather vigorously defended my wife as im want to do, but that doesnt mean i was most effective in answering.

This convention process will be over with sometime in june. It will be apparent to the world that trump is over the 1,237 number. Reporter thats the public spin from paul manifort, a longtime delegate wrangler and privately his recent hiring shows trump team is more worried than they are letting on, predictions of an outright win, but by less than they once thought. All of it an opening for cruz, considered by some one of the most hated men in washington and now with a new headline, maybe likable enough . Sill, a different congressman, congressman paul ryan cant shake speculation that he would swoop in at a contested convention. What really bothers me the most in politics these days reporter videos like this not helping to squash the savior talk. Ryan insisting he doesnt want to be the nominee. The candidates who do, duking it out delegate by delegate. Apparently conscious of questions about why hes not out on the campaign trail trump tweeting that he runs a Major Business at home now in new york and catching up.

Reporter on thorny issue of divorce and remarried catholics the pope says they should be part of church life, but when it comes to receiving communion, that should be addressed case by case. Hes not saying that the rules are not important. What hes saying is it that there are rules and then there are people. Reporter while making it clear samesex unions are not marriage in the eyes of the church he called for greater respect for gays and lesbians.

Eliquis can cause serious, and in rare cases, fatal bleeding. Dont take eliquis if you have an artificial heart valve or abnormal bleeding. If you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. While taking eliquis, you may bruise more easily.
