An employee died Wednesday at Tesla's factory hub in Fremont, California

• Local news station KTVU reported that a worker died at Tesla's factory in Fremont, California.
• The identity of the employee has not yet been released.

A Tesla employee died on the job at the automaker's factory in Fremont, California early on January 19. State authorities have determined that the death occurred due to a "personal medical issue," rather than a work-related incident.

Local news station KTVU broke the story of the fatality, which involved an employee on the factory's powertrain line. The worker has not yet been identified.

Tesla did not respond to Insider's request for comment. KTVU reported that Cal-Occupational Safety and Health Administration is currently investigating the circumstances of the death.

"Tesla, Inc. dba Tesla Motors, Inc. notified Cal/OSHA of a fatality January 19 in Fremont," a spokesperson for the administration said in an email to Insider. "A production associate collapsed while working on the power train line. Cal/OSHA is gathering more information to determine the work-relatedness of this event and whether to conduct an inspection."

On Tuesday, the administration followed up to say that: "Cal/OSHA is not investigating as this fatality was due to a personal medical issue."

Back in December, Tesla's Fremont hub was the site of a homicide. Two Tesla employees — 29-year-old Anthony Solima and 42-year-old Lee Brasier — quarreled on the job. Solima allegedly shot and killed Brasier later that day. He has been charged with murder.
