UPDATE, 6/6 — 2:30 a.m.: Seattle police have identified the suspect as Aaron Ybarra, 26.

One person is in custody after a shooting at Seattle Pacific University left one dead and three people wounded Thursday evening, police said.

“Once again the epidemic of gun violence has come to Seattle,” Mayor Ed Murray said.

Harborview Medical Center spokeswoman Susan Gregg had no additional information on the young man who died. She says a 20-year-old woman is in surgery with critical injuries while a 24-year-old man and a 22-year-old man are in satisfactory condition.

Police said at a press conference that the shooter was confronted and subdued by a student, a building monitor, as he attempted to reload his shotgun. The unidentified suspect was pepper sprayed and pinned to the ground as other students rushed in to help until police arrived, authorities said.

He was described as a 26-year-old man armed with a shotgun, knife and additional ammo. He was not a student at the school, police said.

One witness said he cradled an injured woman and tried to calm her as she panicked. She asked him to call her mom and when he did, there was no answer, according to an ABC reporter.

A professor, speaking to KIRO-TV, said he witnessed the incident.

“I heard a shot … looked outside and I saw a man laying facedown on the ground with another man holding a shotgun over him … at first I thought it was a game or something until I saw he was bleeding,” he said.

“And I went to call security … I heard another shot louder … and when I looked outside there was a man on the ground and someone sitting on top of him — a whole bunch of shotgun shells underneath him,” the professor added.

Kharis Lund, 19, told the Seattle Times she was in her dorm room when she heard emergency sirens go off.

“It was super-terrifying,” she said. “There were a lot of people crying and calling their parents.”

Another student, in the class next door to the shooting, recounted what he heard to KIRO.

“In the middle of class, we just hear a muffled sound … and I heard someone yelling … and I heard someone run by the door,” he said.

“I just saw puddles of blood on the ground,” the student added, referencing what he saw as he left the classroom.

University President Daniel Martin fought back tears during a press conference as he described the bravery of the students who helped subdue the suspect.

“We are a community that relies on Jesus Christ for strength and we’ll need that this time,” he said.

Martin added that he was “not sure” if the shooting had been caught on surveillance tape.

The private Christian university, where just over 4,000 students attend classes, has since lifted the lockdown.

“Our heartfelt prayers are with our entire community,” a message on the school’s website read.
