On October 25, 1983, Ronald Joseph Cole was reported as a missing person to the Fillmore Police Department. During the reporting, law enforcement was advised that Ronald Cole had been missing since May of 1965 and his last known location was a family residence in the 400 block of Foothill Drive in the city of Fillmore. Family members of Ronald Cole believed he was missing under suspicious circumstances and suspected Ronald Cole’s half-brother, David La Fever, was responsible for Ronald Cole’s disappearance. Due to the suspicious circumstance surrounding Ronald Cole’s disappearance, the Ventura County Sheriff’s Office assumed the missing person investigation in August of 1984.
At the time, investigators were unable to find any physical evidence of a crime, a crime scene, or locate Ronald Cole. David La Fever was named a prime suspect in Ronald Cole’s disappearance, but no criminal charges could be substantiated at that time. Ronald Cole’s missing person investigation remained open throughout the years. During the investigation, investigators learned David La Fever passed away on August 12, 2007, in Anchorage, Alaska.
