Oakland police recovered a weapon Friday morning belonging to the man suspected of killing seven people and wounding three others in Monday's Oikos University mass murder, police said.
At about 5:30 a.m. Friday, officers located a gun in a waterway in the 8400 block of Leet Drive, less than a mile from the vocational school. Police said the weapon matches the serial number of a gun purchased by the shooting suspect, One Goh, who was arraigned on murder charges Wednesday.
Police had been searching for the gun in a waterway between the school and the place where Goh was arrested, a Safeway store at 2227 South Shore Center in Alameda. Investigators plan to test the weapon to determine if it was used in the shooting, police said.
"Investigators have worked very hard on this case," Police Chief Howard Jordan said in a statement. "Hopefully, this find will help the families find closure and bring this case to justice."
Seven people died in the shooting at the Christian vocational school on Edgewater Drive when Goh, a 43-year-old Korean national living in Oakland, allegedly opened fire at about 11:15 a.m. Monday.
Three other people were injured in the shooting but survived.
Lydia Sim, 21, of Hayward; Sonam Choedon, 33, of El Cerrito; Grace Eunhea Kim, 23, of Union City, Doris Chibuko, 40, of San Leandro; Judith Seymour, 43, of San Jose; Tshering Rinzing Bhutia, 38, of San Francisco; and Katleen Ping, 24, were killed in the shooting rampage.
Goh surrendered to Alameda police at the supermarket after admitting to a security guard that he had shot several people in Oakland, police said.
Police said Goh is a former student at the school.
Goh was arraigned Wednesday on seven counts of murder and other charges that could make him eligible for the death penalty. He is expected to return to court on April 30, when he is scheduled to enter a plea.
The motive for the shooting is unclear, but Alameda County District Attorney Nancy O'Malley said it appears Goh wanted his tuition back after he voluntarily left the school last November and that he was targeting an administrator there.
Goh is being held at Santa Rita Jail in Dublin without bail.
