Mark Milton, a 64-year-old Moorpark resident, was found dead in the driver’s seat of a U-Haul at a Public Storage facility on Los Angeles Avenue on January 3, 2020. Multiple 9-1-1 calls reporting gunfire prompted the response; investigators from the Ventura County Sheriff’s Office discovered Milton had suffered fatal gunshot wounds.

Authorities identified Elsworth Dennis Cadle, then 67, as the primary suspect. Cadle, a City of Simi Valley bus driver and Milton’s brother-in-law, was located after a nine-hour search driving near Moorpark College; a firearm was recovered from his vehicle. The shooting was reported to have arisen from a personal dispute between the two men. Cadle was charged with first-degree murder and weapons enhancements and pleaded not guilty by reason of insanity; an initial jury trial ended in a mistrial, and a retrial was set for September 2024.

Milton was remembered as a dedicated electrician and a spiritual man who helped others. If anyone knew Mark, his routines, or saw activity around the storage facility that day, please share what was seen.
