Overview of the Incident
A state investigation has determined that the deaths of three Los Angeles County sheriff's deputies in a grenade explosion on July 18, 2025, were the result of "willful" safety violations by the Los Angeles County Sheriff's Department (LASD). The explosion occurred at the Biscailuz Training Facility, killing Detectives Joshua Kelley-Eklund, Victor Lemus, and William Osborn, who were part of the department's arson and explosives team. The deputies had recovered two grenades from a Santa Monica apartment complex the day prior, mistakenly believing one to be inert. The incident marked one of the department's most significant losses in a single event.
Findings of the Investigation
The California Division of Occupational Safety and Health (Cal/OSHA) issued eight citations against the LASD, resulting in approximately $350,000 in fines. The investigation revealed that the department failed to provide adequate training, left explosives unattended, and did not ensure proper safety protocols were followed. Specifically, the deputies did not use appropriate personal protective equipment when handling explosives, and the department failed to document training or evaluate hazards associated with explosive materials.
Legal and Administrative Responses
In January 2026, the LASD appealed the citations, asserting that they had complied with state investigators to the extent permitted by ongoing criminal investigations. However, Cal/OSHA has accused the department of obstructing the investigation by providing limited documentation and heavily redacted records. A lawsuit filed by Cal/OSHA seeks to compel the LASD to release additional documents necessary for completing its investigation.
Criticism and Opposition
Critics have raised concerns about the LASD's handling of the incident and the safety of its operations. Legal claims filed by the widow of Detective Lemus allege that the department failed to provide adequate training and that the deputies did not follow proper procedures when handling the grenades. The claim suggests that the deputies used personal vehicles instead of the department's bomb truck, which contained superior equipment, and that inadequate training contributed to the tragic outcome.
Ongoing Investigations
In addition to the Cal/OSHA investigation, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is also investigating the explosion. The LASD is conducting its own internal inquiries, including a homicide investigation into the deputies' deaths and an investigation into the disappearance of the second grenade.
Official Statements
A spokesperson for the LASD stated that the department is cooperating with Cal/OSHA while balancing the need to protect ongoing investigations. They emphasized their commitment to improving safety protocols and ensuring compliance with legal requirements.
