Oikos University Shooting Oakland California (April 2, 2012)

OAKLAND, Calif. — A 43-year-old former student of a small Christian university in California opened fire at the school Monday, killing at least seven people and setting off an intense, chaotic manhunt that ended with his capture at a nearby shopping center, authorities said.

Police Chief Howard Jordan said One L. Goh surrendered about an hour after the shooting at Oikos University. Jordan initially reported that authorities recovered the weapon used during the rampage, but later clarified that police only recovered enough ballistics evidence to determine that a handgun was used in the rampage.

"It's going to take us a few days to put the pieces together," Jordan said. "We do not have a motive."

Police first received a 911 call at 10:33 a.m. reporting a woman on the ground bleeding. As more calls came in from the school, the first arriving officer found a victim suffering from a life-threatening gunshot wound, he said.

It was an "extremely chaotic scene," Jordan said.

More officers arrived and formed a perimeter around the school on the belief that the suspect was still inside, he said."He didn't look like he had a sign of relief on him. He didn't look like he had much of any emotion on his face," said Lisa Resler, who was buying fruit at Safeway with her 4-year-old daughter when she saw the man.

Goh also called his father soon after the shooting and told him what happened, the police chief said. The father also called authorities, Jordan said.

Police went to the Westlake Christian Terrace senior housing complex on Monday afternoon to speak with a relative of Goh, Nam Ko Young, who's believed to be the man's father, said Young's neighbor, Barbara Ferguson.

Ferguson said she's seen Goh and Young in the lobby and exchanged hellos in the past but that she doesn't know them well.

Jerry Sung, the university's accountant, said the school offers courses in both Korean and English to less than 100 students. He said the campus consisted of one building. Sung said many of its students went on to work in nursing and ministry.
