Police search the bay near Oikus University.
Police in Oakland found a weapon around 5:30 a.m. Friday morning that they believe a gunman used to kill seven people and injure three more in a shooting Monday at a small Christian university.
Investigators said the gun’s serial numbers match a firearm the murder suspect legally purchased a few weeks ago.
The .45-caliber semiautomatic pistol was found in a shallow waterway just a few blocks from Oikos University. The waterway runs near a street suspect One Goh could have traveled to get to the nearby Safeway market where police eventually arrested him.
Oakland city officials said that despite the serial number match, they’re still testing the weapon to make sure it was used in the college shooting.
The gun is a critical piece of evidence in the case against Goh. Earlier this week, Alameda County charged Goh with seven counts of murder and three counts of attempted murder with special circumstances.
District Attorney Nancy O’Malley told reporters she’ll decide whether to seek the death penalty after a preliminary hearing on the case. The next scheduled court date is April 30.
