SEATTLE -- OnFriday, Seattle police said Aaron Ybarra, the suspect in Thursday s deadly shooting at Seattle Pacific University, told police he had been planning a mass shooting and wanted to kill as many victims as possible before killing himself.
On Friday, Ybarra's attorney said he was in a delusional state and he was sorry for his actions.
Ybarra's attorney said he was on suicide watch and wearing a straight jacket.
Paul Lee, 19, of Portland, was killed and two other students were wounded after the gunman entered the foyer at Otto Miller Hall on the Seattle Pacific University campus and started shooting Thursday afternoon.
The four people, including the young man who died, were taken to Harborview Medical Center.
A critically wounded 19-year-old woman, Sarah Williams, remained in intensive care Friday after five hours of surgery, according to the hospital. She was upgraded to serious condition Friday afternoon.
A unnamed 24-year-old man had pellet fragment wounds to his neck and chin. He was released from the hospital Friday evening.
John Meis, 22, injured in the struggle in which he subdued the gunman after pepper-spraying him, was treated and released, officials said.
All four victims were SPU students.
Aaron R. Ybarra, 26, was booked into the King County Jail late Thursday for investigation of homicide, according to police and the jail roster.
According to court documents released Friday, after Ybarra was read his Miranda Rights he told homicide detectives he shot the victims and that he had been planning a mass shooting and wanted to kill as many victims as possible before killing himself.
Friends were not entirely surprised by Ybarra's actions.
He seemed like a good kid, but he was dislodged from reality a little bit, said Jason Wells, a friend of Ybarra.
Wells said the two met at a local bar and stayed friends. Wells said 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 said 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 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 to be 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 happy about his new 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.
