SAN FRANCISCO—A gunman suspected of killing a Northern California police officer who pulled him over to investigate if he was driving drunk is in the country illegally, authorities said on Dec. 27.

Stanislaus County Sheriff Adam Christianson said detectives identified the suspect in the slaying of Cpl. Ronil Singh of the small-town Newman Police Department but didn’t release his name. The attacker is still on the loose, and he said authorities searching for a second day believe he’s still in the area and is armed and dangerous.
