Jaylen Fryberg

Jaylen Fryberg was a Native American and a member of the Tulalip tribe.

Witness Luton could not confirm reports that Fryberg had been bullied. But two weeks ago, according to Luton, Fryberg got in a fight after somebody said "something racist" to him.

Jaylen Fryberg was in the school's cafeteria, went up to a table with students,

"came up from behind ... and fired about six bullets into the backs of them," witness Jordan Luton told CNN.

"They were his friends, so it wasn't just random," Luton said.

The attacker shot five people, killing one, authorities said.  One of the victims was Fryberg's cousin;  family confirmed Shooter Jaylen Fryberg and victim Andrew Fryberg at Harborview are cousins. @KIRO7Seattle

A federal law enforcement official, who spoke on condition of anonymity, the gunman, 14-year-old Jaylen Fryberg, is dead of a self-inflicted gunshot wound. A female student is dead and several more are wounded.
