The mystery surrounding a California teenager who went missing six decades ago has been unraveled after his gunshot-marked skull was discovered nearly 2,000 miles away.

Ronald Joseph Cole, who vanished in May 1965 but was not reported missing until 18 years later, was finally identified in 2024 when his remains were found in Geneseo, Illinois.

Cole was just 19 years old when he disappeared from Fillmore, as reported by the Ventura County Sheriff’s Office.

Although the circumstances of his disappearance are still shrouded in mystery, both law enforcement and The Doe Project, a non-profit organization, suspected foul play was involved.

The Doe Project works globally with authorities to solve cold cases and missing person mysteries that have long baffled investigators.

According to a statement from the sheriff’s office on Wednesday, Cole’s family believed he vanished under suspicious conditions and suspected his half-brother, David La Fever, might have been involved in his disappearance.

The Doe Project also suspected that the 19-year-old had traveled from San Diego to the Fillmore area, staying with family while searching for work.

Despite the police taking over the investigation due to suspicions about Fever, they were stunned to find not a single piece of evidence of foul play, a crime, or even of Ronald himself.

With no evidence to support charges, Fever walked free despite being the prime suspect.

The case went cold but never closed, lingering for decades even after his half brother died in Anchorage, Alaska, in August 2007.

All was quiet for 17 long years until 2024, when the Henry County, Illinois, Sheriff’s Office reopened the case of unidentified human remains discovered southeast of Geneseo in October 1966. 

A ‘human skull with an obvious bullet hole’ was among the remains, and they reinvestigated the case as a homicide. 

Illinois police turned to the DNA Doe Project for help, a nonprofit specializing in identifying human remains.

The nonprofit sent a sample of the remains to Astrea Forensics, a forensic lab, for further analysis. 

Astrea Forensics specializes in obtaining DNA from old or badly damaged remains, aiding investigators in identifying the person. 

Geneseo, Illinois, was where Cole’s remains were discovered, roughly 2,000 miles from the last place he was seen

According to the Ventura County Sheriff’s Office, Cole was 19 years old at the time he vanished from this last known location: the 400 block of Foothill Drive in Fillmore

On January 10, the Henry County Sheriff’s Office learned from the DNA Doe Project that the human remains discovered by the creek finally had a name: Ronald Joseph Cole

The team identified potential family members from the remains, and by May 2025, cold case investigators in Henry County and Ventura County were working side by side.

On January 10, the Henry County Sheriff’s Office learned from the DNA Doe Project that the human remains discovered by the creek finally had a name: Ronald Joseph Cole.

How Cole’s remains ended up roughly 2,000 miles from where he was last seen remains a mystery. 

The Henry County Sheriff’s Office continues to lead the homicide investigation, but no further details have been released.
