Overview

• Investigators served a search warrant on a boat in Marina del Rey Monday but have not disclosed any findings from the operation.
• The action follows a Santa Monica search that yielded explosive materials, including grenades, from a storage unit near Bay Street and Lincoln Avenue.
• Los Angeles County Sheriff’s homicide detectives are leading the investigation with support from the ATF’s National Response Team and the LAPD.
• On July 18, three veteran bomb technicians—Detectives Joshua Kelley-Eklund, Victor Lemus and William Osborn—were killed when a grenade detonated at the Biscailuz Training Academy.
