Accused Seattle Campus Killer Allegedly Confessed How It Was ‘So Fun’

— -- Police have released videotape in which the accused gunman in the deadly June shooting at Seattle Pacific University not only allegedly confesses to pulling the trigger, but describes it as "fun" and says that he wishes he would have shot more people.

Paul Lee, 19, was killed and two other people were injured when Aaron R. Ybarra of Mountlake Terrace, Washington, allegedly opened fire on students in the university's engineering building June 5, a week before the end of the school year.

On the tape, he allegedly described taking that first shot as "fun."

"You're like, 'I can't believe I'm doing this.' But once you do it, you're like, 'Oh, my God. It's so fun,'" he said.

As Ybarra stopped to reload a shotgun, authorities said, senior Jon Meis tackled him and pepper-sprayed him. Meis, a teaching assistant at the school, had been doubling as a security desk monitor that day.

In the taped confession, taken in police headquarters the same day as the shootings and for more than an hour long, Ybarra, now 27, allegedly shared the motive with authorities.

"I just felt nothing but hate -- 100 percent hatred -- towards the world, towards everyone," he allegedly said in the videotape, which was released Tuesday. "I didn't even feel remorse for what I was about to do."

Ybarra, who has pleaded not guilty to first-degree murder, allegedly told detectives that he felt the whole world was against him and that he'd started living in a fantasy world.

"I was lonely growing up. I felt like I started to become psychotic or something," he allegedly said.

He said that he'd stopped taken medication prescribed to him for obsessive-compulsive disorder and transient psychosis and that he'd also stopped going to counseling.

On June 5, Ybarra allegedly said, he packed 75 rounds of ammunition and headed to the campus in hopes of taking hostages.

"I didn't even feel remorse for what I was about to do. ... First guy I shot at, I was so pissed because he didn't take me seriously," he allegedly said on the tape. "I hate when people disrespect me."
