They remembered that on monday, a woman had seen criner lighting a fire in an abandoned building. When firefighters arrived, police took criner to this shelter for homeless youth.

You know, everything thats going on. Its not safe these days. Reporter shot and killed today, two men. An officer and an airman, 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 for an active shooter is now a fact of life on military bases. As a result of that training, we were onscene, 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 block 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.

Reporter dramatic daytime arrests on brussels streets today, five in all. Two of them isis suspects wanted for mass murder. Mohamed 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 stayed in this rented flat just before the attacks in paris. Reporter but he may be tied to a second atrocity. Investigators saying theyre 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. He connects the paris attacks to the brussels attacks. His dna is all over the preparation of the paris attacks. Reporter antiterrorism police are still searching this area, which isnt far from the isis bomb factory where mohamed abrinis dna was found. In november, abrini was filmed at a gas station near paris two days before the killings, with his boyhood friend, salah abdeslam, who also fled the attacks. Next day, the two men were seen with a suicide bomber in a car used in the massacres. Police believe theyre breaking this deadly isis cell. Salah 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 k. , bought the bags used in the airport bombings here and may have been with the suicide bomber at the metro. So they believe theyve caught two men at the very heart of the terror here. Bill neely in europe, thank you.

Reporter and jane sanders with rachel maddow. He has said, okay, lets not use the word unqualified. Lets use the word contrast. Why do i think im better than her .

Reporter and bill clinton asked if this would have happened to a man with the same resum resume. Of course it wouldnt. Reporter meanwhile he was trying to clean up his own controversy after yelling at black lives matter hecklers, for calling drug dealers super predators in the 90s.

But privately his recent hiring shows trumps team is more worried than theyre letting on. A Campaign Source sharing with nbc news 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, now with a new headline. Maybe likeable enough. Still, its a different congressman, speaker paul ryan, who cant seem to shake speculation he could 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.
