(CNN) – A popular freshman shocked friends, fellow students, and teachers when he opened fire at Marysville-Pilchuck High School. The gunman shot five people, killing one, before killing himself, law enforcement officials say.
"It just came out of nowhere. I honestly wouldn't expect it," student Frankie Pina, a friend of the shooter, told CNN.
"We used to be very good friends. We kind of drifted away a little bit. And now this happened," the junior said.
The gunman, whom witnesses identify as Jaylen Fryberg, was not a violent person, said Pina. Fryberg's girlfriend had broken up with him, and his tweets had recently taken a dark turn, he said.
He sent "scary" tweets "about hurting himself and stuff like that," said Pina.
(CNN) – Witnesses say a popular freshman, a member of the football team and the homecoming prince, took a gun to his school, and shot his friends and fellow students.
It's hard to understand, but not uncommon says Dave Cullen, author of "Columbine."
"It's all about the perspective of person. Objectively he may seem popular to us. But the person, especially a kid in high school, doesn't see it that way," Cullen said in an interview with "The Lead with Jake Tapper."
(CNN) – Marysville-Pilchuck High School freshman Jordan Luton was having lunch in the school cafeteria Friday, when a classmate walked in and opened fire.
The shooter walked up to a table where his friends were sitting, said Luton.
"He came up from behind, and had a gun in his hand, and fired about six bullets into the backs of them. And they were his friends, so it wasn't just random," Luton said in an interview with CNN's "The Lead with Jake Tapper."
(CNN) – The suspects involved in two separate attacks in Canada this week were known to government authorities.
The suspect involved in Wednesday's Ottawa shootings, Michael Zehaf-Bibeau, had applied for a Libyan visa and was denied. The man who ran over and killed a Canadian soldier Monday had had his passport confiscated after expressing a desire to go to Syria to fight.
Authorities were aware of these men, and yet both, were able to carry out attacks, and kill Canadian soldiers.
Is there a national security gap?
"There are questions that we're asking in parliament about why these men who had registered as being dangerous weren't under closer surveillance," Member of Parliament Chrystia Freeland said in an interview with CNN's "The Lead with Jake Tapper."
