Who Was Beverly Jean Ribley?

Beverly Jean Ribley was born April 24, 1946. California Department of Justice records describe her as a white woman with brown hair and green eyes, approximately 5 feet 1 inch tall and weighing about 100 pounds. The state database also lists the name Beverley Holman as an alternate name associated with her.

She had turned 29 only three days before she vanished.

At the time she disappeared, Beverly was reportedly associated with a multicolored nightgown and a brown leather purse with a shoulder strap. Dental X-rays are available for comparison with unidentified-person cases.

Beverly Ribley’s Disappearance on April 27, 1975

The last confirmed contact with Beverly occurred at approximately 10:30 p.m. on Sunday, April 27, 1975. According to the San Diego County Sheriff’s Department, she was at her residence in the 2400 block of Trace Road in Spring Valley at the time.

The Sheriff’s Department describes her disappearance as occurring under mysterious circumstances. Investigators found no evidence of foul play, but after speaking with Beverly’s relatives and friends, authorities concluded that simply disappearing was inconsistent with her normal behavior.

A secondary missing-person case profile from The Charley Project provides additional details, reporting that Beverly had spoken with a friend by telephone that evening and was never heard from again. According to that account, when police checked her residence, her vehicle was still parked in the driveway and her cats had been left at the home. The profile states that her nightgown and purse were among the items missing.

Those circumstances have left one of the case’s central questions unanswered: how and why did Beverly leave—or disappear from—her home late that night without her vehicle?

What Investigators Know

There is no publicly disclosed evidence showing where Beverly went after approximately 10:30 p.m. on April 27.

The publicly available official case description does not identify a confirmed witness who saw Beverly physically leave the property, a vehicle she may have entered, a destination she intended to visit, or a person responsible for her disappearance.

Authorities have also not publicly classified Beverly’s case as a confirmed homicide. It remains categorized as a missing-person investigation even though it is handled and publicized through the San Diego County Sheriff’s Homicide Detail and its cold-case program.

This distinction is important: although the circumstances are unusual and investigators have continued seeking leads, the publicly released information does not establish that Beverly was murdered.

The Evidence Left Behind

One of the most striking aspects of Beverly Ribley’s disappearance is how little appears to have left the residence with her.

The California Department of Justice lists a multicolored nightgown and brown leather shoulder-strap purse in connection with what Beverly was wearing or carrying when she disappeared.

The Charley Project additionally reports that Beverly’s car remained in the driveway and that her cats were left unattended at the residence.

If those circumstances accurately reflect the original investigation, they suggest that Beverly did not leave in her own vehicle and may not have been preparing for a prolonged absence.

They do not, however, reveal whether Beverly left willingly, met someone outside the residence, was picked up by another person, or encountered circumstances that prevented her from returning.

Conflicting Information in Online Case Records

Some online sources contain discrepancies regarding Beverly’s physical description and age.

The California Department of Justice and San Diego County Sheriff’s Department identify Beverly as approximately 5 feet 1 inch tall and 100 pounds, while The Charley Project currently gives a height of 5 feet 4 inches. Official California records are therefore used here for her height.

The Charley Project also lists Beverly as 31 at the time of her disappearance. However, California records give her date of birth as April 24, 1946, and her disappearance date as April 27, 1975, establishing that she had just turned 29 years old. The San Diego County Sheriff likewise identifies her as 29.

Latest Public Investigation Information

As of September 2026, Beverly Jean Ribley remains included on the San Diego County Sheriff’s public list of cold-case homicide and missing-person investigations.

The Sheriff’s Homicide Detail continues to request leads from anyone who may know what happened to her. Current public contact information includes the Homicide Detail during business hours, the Sheriff’s Communications Center outside business hours, and San Diego County Crime Stoppers for anonymous information.

A search of publicly available case information did not locate a later official announcement identifying a suspect, announcing an arrest, confirming Beverly’s remains had been recovered, or declaring the case solved.

California’s missing-person database also continues to carry Beverly’s record under San Diego County Sheriff’s Department case number 425028.

Her case is also associated with NamUs MP18213, according to case-information records reproduced by Uncovered from NamUs data.

Why Beverly Ribley’s Case Remains Significant

Beverly disappeared at a time when many of today’s investigative resources did not exist. There were no mobile-phone location records, widespread residential surveillance cameras, consumer DNA databases, or digital communication histories investigators could immediately examine.

Yet her case still contains information that could potentially be useful today. California records indicate that dental X-rays are available, which can assist investigators when comparing missing people with unidentified remains.

Cold cases can also change when people who withheld information decades earlier decide to speak, relationships shift, previously unknown witnesses are located, or old evidence is examined using newer forensic techniques.

Even a seemingly minor recollection about Beverly’s activities, acquaintances, telephone conversations, visitors, transportation, or movements around April 27, 1975 could provide investigators with information that was never documented at the time.

Someone May Still Know What Happened

Beverly Jean Ribley disappeared from Spring Valley more than 50 years ago, but her case has not disappeared from law-enforcement records.

Her last known contact places her at her Trace Road residence around 10:30 p.m. on April 27, 1975. Her disappearance was regarded as highly unusual by those who knew her, and she has never been located.

Anyone who knew Beverly in 1975, remembers people associated with her, heard an unexplained story about her disappearance, or possesses information that may once have seemed insignificant is encouraged to contact the San Diego County Sheriff’s Homicide Detail or San Diego County Crime Stoppers.

After more than five decades, one previously unknown detail could still help explain what happened to Beverly Jean Ribley.
