SEATTLE - The Seattle Times cites a law enforcement source Friday that said the suspect in Thursday s deadly shooting at Seattle Pacific University was fascinated with mass shootings, including the 1999 Columbine massacre.

Paul Lee, 19, of Portland, was killed and two other young people were wounded after the gunman entered the foyer at Otto Miller Hall on the Seattle Pacific University campus and started shooting Thursday afternoon.

Four people, including the young man who died, were taken to Harborview Medical Center. A critically wounded 20-year-old woman, Sarah Williams, remained in intensive care Friday after five hours of surgery, according to the hospital. A unnamed 24-year-old man was in satisfactory condition.

John Meis, 22, injured in the struggle in which he subdued the gunman after pepper-spraying him, was treated and released, officials said.

Aaron R. Ybarra, 26, was booked into the King County Jail late Thursday for investigation of homicide, according to police and the jail roster.

He seemed like a good kid, but he was dislodged from reality a little bit, said Jason Wells, a friend of Ybarra.

Wells says the two met at a local bar and stayed friends. Wells says Ybarra had an alcohol problem, so he took him under his wing.

I tried to get him on the right track, even letting him sleep on my couch. He kind of looked at me like a big brother, Wells said.

Wells can t remember any talk about guns or Seattle Pacific University from Ybarra. But, he says there were a few times when Ybarra acted strangely.

He would say, I m going to kill everyone , Wells said. I never took him seriously.

The Seattle Times reported that the law enforcement source said Ybarra was hellbent on killing a lot of people before taking his own life. The newspaper was told that police could not find any motive, including a reason why the campus was chosen.

A source tells KING 5 News that Ybarra was enrolled in the Washington Aerospace and Research Center at Edmonds Community College.

Late Thursday and early Friday, police searched a house in Mountlake Terrace that was believed tied to Ybarra.

The Times also reported that the suspect's father, Ambrose Ybarra, said he didn't know anything about the shooting.

We just hope he's safe, he told the newspaper. It's upsetting to have these accusations thrown around. We're in emergency mode. We are trying to stay calm.

The paper said Zack McKinley described himself as one of Ybarra's closest friends and said he was super happy and friendly.

McKinley said the attack was puzzling because Ybarra was happy to have just started a job bagging groceries at a store.

He said Ybarra didn't do drugs or drink alcohol and spent time writing. Ybarra could get emotionally low, but McKinley said he had a good group of friends and never saw him depressed.

On Thursday evening, people packed the First Free Methodist Church on campus for a service of prayers and song. So many people crowded into the building that dozens of people gathered on a lawn near the church and formed their own groups as the sun set.

We're a community that relies on Jesus Christ for strength, and we'll need that at this point in time, said Daniel Martin, university president.

About 4,270 undergraduate and graduate students attend the private Christian university. Its 40-acre campus is in a leafy residential neighborhood about 10 minutes from downtown Seattle. The school canceled classes and other activities Friday.

The gun violence follows a spate of recent shootings on or near college campuses.

Last month, according to police, Elliot Rodger killed six people and injured seven before turning his gun on himself in a rampage in Isla Vista, California, near two universities.

Seven people were killed and three injured when a 43-year-old former student opened fire at a tiny Christian school, Oikos University, in Oakland, California, in 2012. A gunman killed five people and injured 18 when he opened fire in a Northern Illinois University lecture hall in 2008.

In 2007, 32 people were fatally shot in a dorm and classroom at Virginia Tech in Blacksburg, Virginia, before the gunman killed himself.

Seattle Mayor Ed Murray, noting previous mass shootings in the city, said: Once again the epidemic of gun violence has come to Seattle.
