We are going to start with the deadly school shooting in Washington state. Students sprinting outside to get away from a killer who turned a cafeteria there into a crime scene. This was not an outcast. He was a popular kid, a football player who had just been named homecoming prince, and Neal Karlinsky has the latest from outside the high school in Washington, Neal. Reporter: Good morning. The school remains locked down this morning, still very much an active crime scene. Investigators trying to understand why a popular student would allegedly go on a shooting spree. We have information of a possible shooting at at high school in the cafeteria. Reporter: 10:39 A.M., the call from 911 from inside the school. An active shooter for now. Reporter: Witnesses calling into the Seattle station. There are five to six shots. I counted five, but think there was six. Reporter: Emergency responders swarming the area. There was a student gunman methodically shooting kids at a lunch table inside the school's cafeter cafeteria. With we get another gunny. Reporter: Moments later, the suspect is reported dead from a gunshot wound. Another student is dead, and two of the injured were the shooters' own cousins. They got in a fight, and had it going on. Reporter: This year's freshman homecoming prince. While not identified by police, law enforcement sources say he is Jaylen fryberg, a football player and popular student. From what I heard, there were a couple bowling incidents where people had said some things about him in a class. And, you know, he -- the way he handled it, he did fight the kids. Reporter: Twitter offers some clues, writing Thursday morning, it won't last. It'll never last. He seemed to be upset earlier in the week, tweeting, it breaks me, it actually does. I know it seems like I'm sweating it off, but I'm not and I never will be able to. We're all going to pray together. We're all one big family at home that was there. That was sitting around the table. One big family. That's the ones that got shot. Reporter: Three of the victims remain in very critical condition this morning. The alleged shooter's family, members of a prominent native American tribe have remained in seclusi seclusion. They released a statement, they are saddened and shocked. Thank you. This was a nightmare for the students. Should have been a fun lunch period. Here, more of what they saw in their own words. Turned around and saw him stand up, and then gunfire. Four shots went off. I thought it was fire crackers and everyone started ducking under the tables. It was loud bangs, and everyone dropped to the floor and ran out. Gun shots, and ricochetted off something and hit me. When I fell over, got up and there was someone laying on the ground. And everyone started screaming, run, it's a gun. And someone has a gun, so we ran into a classroom. Saw everyone running and I ran. I don't know how to comprehend it at this point, you know? We all ran into the woods and we went to the back gate. And it was closed, and we're all trying to help each other hop over the fence. There was so much screaming and crying and confusion. No one knew what was happening. Just really shocking to find out family had been shot. They were my friends. And the question so many are asking is why.
