Update: Officials Hail Hero Students in Seattle Pacific University Shooting

Quick-thinking students jumped on a man who opened fire in a campus building Thursday at Seattle Pacific University, pinning him to the ground before he could reload, shoot and kill more people, police said.

One man was killed and three other people were injured, one of them critically, Seattle police said. A suspect, described as a 26-year-old white male who wasn't a student, was in custody.

The man was identified by police as Aaron Ybarra. Assistant Police Chief Paul McDonagh said the suspect would be booked for investigation of murder.

McDonagh said it appeared that the man — who was armed with a shotgun, a knife and an unspecified number of extra rounds of ammunition — acted alone, but he said officers were following up on the possibility that he may have had an accomplice.

Susan Gregg, a spokeswoman for Harborview Medical Center, said four people were treated. One - a 19-year-old male - later died, while a woman in her 20s was in critical condition following a five-hour surgery, Gregg said. Of the two others treated, one 24-year-old male was in satisfactory condition while a 22-year-old male was treated and released, she added. NBC station KING of Seattle.
