A devastating explosion at a Los Angeles County Sheriff’s Department training facility has resulted in the deaths of three veteran deputies. The deceased, Detectives Joshua Kelley-Eklund, Victor Lemus, and William Osborn, had a combined 74 years of service. Investigators have determined that the device responsible for the blast was a grenade, which the deputies mistakenly believed to be inert. Inquiries are ongoing, with a search warrant obtained for a location in Marina del Rey tied to the incident, as well as potential links to a Santa Monica apartment. This incident marks the largest loss of life for the Sheriff’s Department since its founding. The tragedy has profoundly affected the local law enforcement community and the families of the fallen deputies.
