Jeannette was reportedly seen getting into a faded brown Chevrolet pickup driven by a young white man described as having an Afro-style hairstyle. She was never seen or heard from again. Her disappearance occurred during the period associated with the unsolved Santa Rosa Hitchhiker Murders.

Who Was Jeannette Kamahele?

Jeannette Kamahele was born February 10, 1952. California’s current missing-person database spells her first name Jeanette, while many contemporary and later sources use Jeannette. She was of Hawaiian descent, and different databases have classified her race variously as Pacific Islander, Asian, or “Other Asian.”

At the time she disappeared, Jeannette was 20 years old, approximately 5 feet 5 inches tall and 120 pounds, with black hair and brown eyes. California authorities list a large birthmark on her right torso. Other case records state that she wore a dental bridge.

Jeannette had graduated from Yokohama American High School in Japan in 1970 and later attended Santa Rosa Junior College in Northern California. She lived with a roommate in the 900 block of Sierra Avenue in Cotati and did not have her own vehicle, making hitchhiking a regular means of transportation.

The Morning Jeannette Kamahele Disappeared

On Tuesday, April 25, 1972, Jeannette reportedly left home at approximately 9:30 a.m. to attend classes at Santa Rosa Junior College.

She was seen near the Highway 101 on-ramp in Cotati, hitchhiking north toward Santa Rosa. According to case accounts, one of Jeannette’s friends saw her and planned to stop to give her a ride. Before the friend could reach her, however, another vehicle stopped.

Jeannette reportedly entered a faded brown Chevrolet pickup truck. The driver was described as a white man believed to be approximately 20 to 30 years old with an Afro-style or bushy hairstyle. Some historical accounts describe a homemade wooden camper attached to the truck.

That was the last known sighting of Jeannette.

She did not arrive at her classes. Her roommate reportedly contacted her teachers and learned that Jeannette had been absent throughout the day. She was subsequently reported missing.

The Santa Rosa Hitchhiker Murders Connection

Jeannette vanished during one of Northern California’s most disturbing series of unsolved crimes.

Between 1972 and 1973, multiple girls and young women disappeared while hitchhiking in or around Sonoma County. Most were later found murdered along rural roads, creek beds, or steep embankments.

Jeannette is frequently included among the potential victims of what became known as the Santa Rosa Hitchhiker Murders, although no remains identified as hers have ever been recovered.

Among the other victims associated with the series were Yvonne Weber, Maureen Sterling, Kim Wendy Allen, Lori Lee Kursa, Carolyn Davis and Theresa Walsh.

Investigators historically considered the possibility that one offender was responsible for multiple crimes, although no person has ever been convicted of the Santa Rosa Hitchhiker murders.

The similarities make Jeannette’s disappearance significant: she was a young woman hitchhiking in the same general region and during the same period, and she apparently disappeared immediately after entering a stranger’s vehicle.

Still, without Jeannette’s remains or definitive physical evidence linking her disappearance to the other cases, the connection remains a theory rather than a proven fact.

The 1979 Jane Doe Discovery

A major development occurred in July 1979 when skeletal remains belonging to a young woman were discovered in a ravine off Calistoga Road.

Because of the estimated age of the remains and their location near sites connected with the Santa Rosa cases, investigators initially considered whether the unidentified woman might be Jeannette.

Dental comparisons ultimately excluded Jeannette.

The discovery demonstrated one of the continuing challenges in Jeannette’s case: determining whether unidentified remains recovered elsewhere in California or surrounding states could belong to her.

Suspects and Theories

Several notorious names have been discussed over the decades in connection with the broader Santa Rosa murders, including Ted Bundy and the unidentified Zodiac Killer.

Ted Bundy received particular attention when Sonoma County investigators revisited the murders using modern investigative techniques. A 2011 report stated that investigators were examining whether DNA or other evidence could potentially connect Bundy to the cases.

The Charley Project subsequently describes Bundy as having been cleared in Jeannette’s disappearance. However, publicly accessible primary law-enforcement material explaining exactly how that conclusion was reached is limited.

The Zodiac Killer has also been suggested by writers and independent researchers, but there is no publicly established evidence identifying Zodiac as Jeannette’s abductor.

Other individuals and theories have circulated in books, websites and discussion forums. None has resulted in a publicly announced arrest or prosecution in Jeannette’s disappearance.

Renewed Investigation and DNA

Decades after Jeannette vanished, Sonoma County investigators revisited the Santa Rosa Hitchhiker cases.

In 2011, the San Francisco Chronicle reported that investigators hoped modern DNA technology could help reexamine evidence connected with the murders. A friend of Jeannette told the newspaper that efforts were also underway to have Jeannette’s DNA information entered into the National Missing and Unidentified Persons System so unidentified remains could potentially be compared against her profile.

California’s current missing-person record continues to list Jeannette as missing and identifies the Sonoma County Sheriff’s Office as the reporting agency.

Recent Comparisons With Unidentified Remains

More recent activity has centered partly on independent researchers attempting to compare Jeannette with unidentified women.

In February 2025, a researcher submitted an unidentified woman known as the Phelan Jane Doe as a possible match. According to a later Websleuths update, the proposed comparison was forwarded to law enforcement, and Jeannette’s NamUs record was reportedly updated on July 8, 2025 to show that the Phelan Jane Doe was not Jeannette.

Another potential comparison involved an unidentified woman whose skeletal remains were recovered near Gilroy in Santa Clara County in 1980.

A researcher submitted the comparison to the respective agencies in late 2025. In correspondence reproduced publicly on Websleuths, the Santa Clara County Medical Examiner reportedly said there was insufficient information to either confirm or exclude the match. The same researcher posted a response attributed to the Sonoma County Sheriff’s Office stating that officials had contacted the medical examiner but DNA could not currently be obtained from the unidentified remains.

These emails were posted by a forum participant rather than released through an official law-enforcement press statement, so the information should be treated as a useful investigative lead rather than independent confirmation of an active official comparison.

As of September 11, 2026, California’s public missing-person database continues to list Jeannette as missing. I found no public announcement that she has been located, identified among unidentified remains, or that anyone has been arrested in connection with her disappearance.

Why Jeannette Kamahele’s Case Remains Important

More than five decades after Jeannette disappeared, several fundamental questions remain unanswered.

Who was driving the brown Chevrolet pickup? Where did the driver take her? Was her disappearance connected to the murders of other young hitchhikers around Santa Rosa, or was she the victim of an unrelated offender?

Most importantly, where is Jeannette?

Her case remains identifiable through NamUs MP8069 and Sonoma County Sheriff’s Office case 267999. Advances in forensic genealogy, DNA analysis and the continued identification of decades-old Jane Does have demonstrated that cold cases once considered almost impossible to resolve can still produce answers.

Anyone with information about Jeannette Kamahele’s disappearance should contact the Sonoma County Sheriff’s Office.
