Victims

Maureen Sterling and Yvonne Weber

Maureen Louise Sterling, 12, and Yvonne Lisa Weber, 13, both students at Herbert Slater Middle School, vanished around 9 p.m. on February 4, 1972, after a visit to the Redwood Empire Ice Arena. Hitchhiking was commonplace among young people at that time, and the girls were last seen attempting to hitch a ride on Guerneville Road, northwest of Santa Rosa.

In a twist that adds a layer of intrigue, an acquaintance of the girls later recalled that they had spoken of a tall, slender man who had approached them, asking if they wanted to smoke marijuana. The friend declined to join them, and the man she later identified in the ice arena lobby bore a striking resemblance to the infamous serial killer Ted Bundy. Described by her friend as being dressed to appear older, the girls disappeared shortly after that encounter.

Their bodies were discovered on December 28, 1972, approximately 2.2 miles north of Porter Creek Road on Franz Valley Road, down a steep embankment about 66 feet off the east side of the roadway. At the scene, police unearthed a single earring, orange beads, and a 14-carat gold necklace with a cross—items that Sterling's mother would later identify as belonging to her daughter. Disturbingly, binding materials found in the brush suggested that the girls had been restrained by their perpetrator(s). Notably, no clothing or personal items were recovered.

Kim Wendy Allen

Kim Wendy Allen, 19, a Santa Rosa Junior College art student, frequently hitchhiked despite warnings from her mother and college professors about the dangers. On March 4, 1972, she accepted a ride from two men who dropped her off near the Bell Avenue entrance to Highway 101. Tragically, her body was discovered the next day, lying down an embankment in a creek bed 20 feet off Enterprise Road in Santa Rosa.

Allen had been bound at her wrists and ankles, raped, and slowly strangled with a cord for approximately thirty minutes. Investigators recovered semen from her body, alongside a single gold loop earring. Marks at the top of the embankment indicated that the assailant may have slipped or fallen while disposing of her body. The two men who had given her a ride were ruled out as suspects after one passed a polygraph test.

Even more unsettling, Allen's checkbook was found deposited in a drive-up mailbox across from the Kentfield Post Office on March 24, 1972, twenty days after her murder. Police suspected that fingerprints on the checkbook could belong to the murderer. When her body was discovered, an oily substance, similar to that used in machine shops, was found on her right side.

Lori Lee Kursa

Lori Lee Kursa, just 13 years old, was reported missing by her mother on November 11, 1972. She had last been seen while shopping with her mother and was later believed to have run away. On December 14, 1972, her frozen remains were found in a ravine off Calistoga Road, northeast of Rincon Valley in Santa Rosa. The killer had thrown her body at least 30 feet over an embankment, with the cause of death determined to be a broken neck, resulting in compression and hemorrhage of the spinal cord.

Two tips to police indicated possible sightings of Kursa shortly before her disappearance, including one witness who described seeing two men with a girl resembling her. Authorities theorized that Kursa may have been kidnapped, stripped of her clothing, and suffered the fatal injury while attempting to escape her captors.

Carolyn Davis

Carolyn Nadine Davis, 15, ran away from her home in Shasta County on February 6, 1973. After spending months on the road, she was last seen hitchhiking on July 15, 1973, near the Highway 101 ramp in Garberville, California. Tragically, her body was discovered on July 31, 1973, just three feet from where the remains of Sterling and Weber had been found months earlier.

The cause of death was later determined to be strychnine poisoning, occurring 10 to 14 days before her body was found. The exact method of poisoning could not be established, and it remained unclear if she had been sexually assaulted. Notably, an injury to her right earlobe suggested an attempted ear piercing, while a witchcraft symbol, which authorities identified as an occult symbol, was found near her body.

Theresa Walsh

Theresa Diane Smith Walsh, 23, left her home in Miranda in the winter of 1973 to escape her husband and young son. A hitchhiker by nature, she last attempted to thumb a ride on December 22, 1973, at Zuma Beach in Malibu. Six days later, her partially submerged body was found in Mark West Creek. She had been hogtied, sexually assaulted, and strangled, with her death estimated to have occurred about a week prior.

Sonoma County Jane Doe

On July 2, 1979, the skeletal remains of an unidentified young white female were discovered in a ravine off Calistoga Road, merely 100 yards from where Lori Kursa's body had been found seven years earlier. Initially believed to belong to Jeannette Kamahele, further examination proved otherwise. This victim had been hogtied as well and bore a fractured arm around the time of her murder. Sadly, no clothing or definitive cause of death was ever established.


Possible Victims

Lisa Michele Smith

Lisa Michele Smith, 17, was last seen hitchhiking near her foster home on March 16, 1971. Reports of her being picked up by a man who brandished a gun surfaced shortly after she was reported missing, but she disappeared again after briefly being located. As of 2011, her fate remains uncertain, with police suspecting she may have been a victim of homicide linked to the other cases.

Jeannette Kamahele

Jeannette Kamahele, 20, was last seen hitchhiking on April 25, 1972. Witnesses reported that she entered a faded brown Chevrolet pickup truck, but her body has never been found.

Kerry Ann Graham and Francine Marie Trimble

Kerry Ann Graham, 15, and Francine Marie Trimble, 14, disappeared on December 16, 1978, while en route to a shopping mall in Santa Rosa. Their remains were discovered in July 1979, approximately 80 miles from where they went missing. Due to the advanced decomposition, causes of death could not be established, but both were considered homicide victims.


1975 Report on Additional Victims

In a 1975 report, the FBI suggested that fourteen unsolved homicides between 1972 and 1974 might be attributed to the same perpetrator, including the victims already mentioned and several others. Each case bore similarities, pointing to a potential serial killer operating in the area.


Other Potential Connections

Law enforcement has explored possible links between the Santa Rosa murders and other homicides across California and beyond, including connections to the notorious Zodiac Killer. Robert Graysmith, in his book Zodiac Unmasked, even included the Santa Rosa victims in a list of potential Zodiac victims.


Suspects

The Zodiac Killer

The Zodiac Killer remains a suspect due to various connections, including symbols found in his letters and the nature of the murders. However, law enforcement has generally ruled out this possibility, citing the sexual nature of the Santa Rosa crimes.

Arthur Leigh Allen

Arthur Leigh Allen, a Vallejo resident, was a prime suspect due to his history of criminal behavior and his proximity to the Santa Rosa area during the time of the murders. He was known for collecting chipmunk hairs, which were found on the victims.

Ted Bundy

After his capture for similar crimes, Ted Bundy was also investigated as a potential suspect. However, he was ruled out based on his whereabouts during the time of the murders, as well as the belief that the killer likely resided in the Santa Rosa area.

Jim Mordecai

The 2024 HBO Max documentary The Truth About Jim explored Jim Mordecai, a high school teacher with no prior criminal record, as a possible perpetrator. After his death, family members found mismatched female jewelry, including a hoop earring matching one worn by a victim.

Jack Bokin

Jack Alexander Bokin, a serial rapist who died in prison, has been suggested as a potential suspect due to his extensive criminal history and the violent nature of his offenses.


Conclusion

The Santa Rosa hitchhiker murders remain a haunting enigma in the annals of true crime, a chilling reminder of the risks faced by young women in a time when hitchhiking was a common practice. With the mystery still unsolved, the families of the victims continue to seek closure, and investigators remain vigilant in their pursuit of justice.
