A mechanic died Thursday, November 12, after becoming trapped beneath a 53-foot trailer at an off-site Amazon facility in Otay Mesa, south of San Diego.

The California Department of Forestry and Fire Protection (Cal Fire) confirmed the fatality, although authorities have not yet determined what caused the accident, according to ABC 10News.

An Amazon spokesperson said the victim was not a company employee but an outside mechanic who had been performing repair work on a trailer that was experiencing mechanical problems.

Officials have not released details about how the mechanic became trapped beneath the vehicle or how long he remained there before his death was confirmed.

Following the incident, the California Division of Occupational Safety and Health (Cal/OSHA) was notified and sent representatives to the facility to investigate.

The agency is expected to examine the conditions under which the repair work was being performed and determine whether workplace safety regulations were followed. No potential violations have been announced, and the victim's identity has not been released.

The fatal accident highlights the risks associated with maintaining and repairing heavy-duty vehicles. According to figures from California's Department of Industrial Relations cited by ABC 10News, the state recorded 419 work-related deaths in 2024, compared with 504 in 2022.

Transportation-related incidents accounted for approximately 32% of workplace fatalities, making them the leading cause of work-related deaths in California.

Cal/OSHA's investigation is ongoing as authorities work to determine exactly what happened at the Otay Mesa facility.
