The suspect was identified as Gustavo Perez Arriaga, 33, according to Stanislaus County Sheriff Adam Christianson. Arriaga was at a Kern County home upon being arrested, Christianson said. Kern County is about 200 miles south of where the shooting occurred.

Singh, 33, pulled over the suspect just before 1 a.m. Wednesday and a few moments later called out "shot fired" over the radio.

Other officers found Singh shot and took him to a hospital, where he was pronounced dead, police said. Singh was a native of Fiji and joined the force in July 2011.
