According to reports, Anthony Solima, 29, shot and killed his coworker from the Fremont, CA Tesla factory in the parking lot of their job after the victim got off of work. Authorities say Solima abruptly left the factory earlier in the day after going at it with the victim.

Later that afternoon, the victim was found in the parking lot with multiple gunshot wounds. While executing a search warrant on Solima later that night, authorities found a loaded short-barrel rifle and expended casings in the suspect’s car.

He was subsequently arrested on homicide charges. Authorities have not disclosed the identity of the victim.
