The Santa Rosa hitchhiker murders were a series of at least seven unsolved homicides involving female hitchhikers that took place in Sonoma County and Santa Rosa of the North Bay area of California in 1972 and 1973. All of the victims were found nude in rural areas near steep embankments and/or in creek beds near roads.

Maureen Sterling and Yvonne Weber
Maureen Louise Sterling and Yvonne Lisa Weber, both 12-year-old Herbert Slater Middle School students, disappeared around 9 pm on February 4, 1972, after visiting the Redwood Empire Ice Arena. They were last seen hitchhiking on Guerneville Road, northwest of Santa Rosa. Their bodies were found December 28, 2.2 miles north of Porter Creek Road on Franz Valley Road, down a steep embankment approximately 66 feet off the east side of the roadway. A single earring, orange beads and a 14-carat gold necklace with cross were found at the scene. The cause of death could not be determined from the skeletal remains.
Kim Wendy Allen
Santa Rosa Junior College art student Kim Wendy Allen, 19, was given a ride by two men on March 4, 1972, from her job at Larkspur Natural Foods to San Rafael. They last saw her at approximately 5:20 pm hitchhiking to school near the Bell Avenue entrance to Highway 101, northbound, carrying a large wooden soy barrel with red Chinese characters on it. Her body was found the following day down an embankment in a creek bed twenty feet off Enterprise Road in Santa Rosa. The victim had been bound at the ankles and wrists, raped and slowly strangled with a cord for an estimated thirty minutes. Semen was recovered from the body and a single gold loop earring was found at the site. Markings at the top of the embankment and a possible leg impression in the loam indicated the assailant likely slipped or fell while throwing or transporting the body. The two men who gave her a ride, one of whom was given and passed a polygraph test, were ruled out as suspects.
Lori Lee Kursa
Lori Lee Kursa, 13, a Lawrence Cook Middle School student, had been reported missing by her mother on November 11, 1972 after disappearing while they shopped at a U-Save and was last seen on November 20 or 21 in Santa Rosa while visiting friends, having deliberately run away. She had been known to hitchhike occasionally. Her frozen remains were located on December 14 in a ravine approximately fifty feet off Calistoga Road, northeast of Rincon Valley in Santa Rosa. The killer had thrown the body at least thirty feet over an embankment. The cause of her death was a broken neck with compression and hemorrhage of the spinal cord. The victim had not been raped and likely died one to two weeks prior to discovery. A possible witness to her abduction later came forward stating that on an evening somewhere between December 3 and 9, while on Parkhurst Drive he saw two men push a girl fitting Kursa's description into the back of a van driven by a Caucasian man with an Afro-type hairstyle. The vehicle then sped north on Calistoga Road.
Carolyn Davis
Carolyn Nadine Davis, 14 years old, ran away from her home outside Anderson in Shasta County on February 6, 1973 but disappeared July 15 after being dropped off by her grandmother at the Garberville Post Office. She was last seen hitchhiking that afternoon near the Highway 101 ramp, southbound, in Garberville. Her body was discovered on July 31 just three feet from where the remains of Sterling and Weber had been recovered seven months prior. Cause of death was strychnine poisoning 10–14 days before discovery. It could not be determined if she had been raped. Investigators postulated that her body had been thrown from the road as the hillside brush appeared undisturbed.
Theresa Walsh
Theresa Diane Smith Walsh, 23, of Miranda, was last seen on December 22, 1973, at Zuma Beach in Malibu, intent on hitchhiking to Garberville and joining her family for Christmas. Her partially submerged body was found six days later by kayakers in Mark West Creek. She had been hogtied with clothesline rope, sexually assaulted, strangled and was determined to have been dead approximately one week. Due to recent heavy rains in the area, high water marks suggested the body could have drifted several miles.
Unidentified remains
On July 6, 1979, skeletal remains were found in a ravine off Calistoga Road approximately one hundred yards from where the body of Lori Lee Kursa had been recovered seven years earlier. Due to the age of the remains, authorities initially believed them to be those of Jeannette Kamahele until a comparison of dental records later proved negative. The victim had been hogtied and her arm fractured around the time of her murder but there was no other evidence to establish a cause of death. It was determined that the unidentified victim was approximately 19 years old, wore contact lenses, had red or auburn hair and at one time had broken a rib which was healed by the time of the murder.
Lisa Smith
Lisa Smith, 17, of Petaluma was last seen at about 7 pm on March 16, 1971, hitchhiking along Hearn Avenue in Santa Rosa. On March 29, The Press Democrat reported that a girl using the name "Lisa Smith" had recently been released after being treated at Novato General Hospital for injuries the victim claimed were sustained after being picked up by a man while hitchhiking and beaten. It was never determined if this was the same Lisa Smith. Her body was never found and Smith is officially a missing person.
Jeannette Kamahele
Jeannette Kamahele, 20, a Santa Rosa Junior College student, was last seen on April 25, 1972, hitchhiking near the Cotati on-ramp of Highway 101. A friend witnessed her likely abduction and reported that she entered a faded brown Chevrolet pickup truck fitted with a homemade wooden camper and driven by a 20- to 30-year-old Caucasian male with an Afro hairstyle. Her body has never been found.
FBI report on additional victims (1975)
In 1975, the Federal Bureau of Investigation issued a report stating that fourteen unsolved homicides between 1972 and 1974 were committed by the same perpetrator. These comprise of the six found victims (as of 1975) and the following:
The Zodiac Killer
The unapprehended Zodiac Killer is a suspect. due to similarities between an unknown symbol on his January 29, 1974 "Exorcist letter" to the San Francisco Chronicle, in which he claims 37 victims, and the Chinese characters on the missing soy barrel carried by Kim Allen, as well as stating an intention to vary his modus operandi in an earlier November 9, 1969 letter to the San Francisco Chronicle: "I shall no longer announce to anyone. when I comitt my murders, they shall look like routine robberies, killings of anger, + a few fake accidents, etc." (sic)
Arthur Leigh Allen
Arthur Leigh Allen, of Vallejo, owned a mobile home at Sunset Trailer Park in Santa Rosa at the time of the murders. He had been fired from his Valley Springs Elementary School teaching position for suspected child molestation in 1968 and was a full-time student at Sonoma State College. Allen was arrested on September 27, 1974, by the Sonoma County Sheriff's Office and charged with child molestation in an unrelated case involving a young boy. He pleaded guilty on March 14, 1975, and was imprisoned at Atascadero State Hospital until late 1977. Robert Graysmith, in his book Zodiac Unmasked, claims that a Santa Rosa County sheriff revealed that chipmunk hairs were found on all of the Santa Rosa Hitchhiker victims and that Allen had been collecting and studying the same species. Allen was the main suspect in the Zodiac case from 1971 until October 2002, ten years after his death, when his DNA was compared to a partial DNA profile obtained from saliva recovered on the underside of a postage stamp and envelopes from verified Zodiac letters. Results were a conclusive non-match. Fingerprints in blood recovered from the taxicab of Zodiac murder victim Paul Stine, a writer's palm print found on the Zodiac letter of January 29, 1974, and handwriting exemplars further ruled out Allen as Zodiac.
Ted Bundy
After his capture for similar crimes in Washington, Colorado, Utah and Idaho, Ted Bundy was suspected in the murders. Bundy had spent time in neighboring Marin County, but was ruled out by a Sonoma County detective in the 1970s and again in 1989. Detailed credit card records and known whereabouts of Bundy reveal he was in Washington on the dates of some of the disappearances.
Other suspects
Fredric Manalli, a 41-year-old Santa Rosa Junior College creative writing instructor was suspected when, after his August 24, 1976 death in a head-on collision on Highway 12, sadomasochistic drawings he had created depicting former student Kim Wendy Allen were discovered among his belongings. Kenneth Bianchi and Angelo Buono, Jr., the Hillside Stranglers of Los Angeles, were also considered suspects at one time.
Current status
These cases represent eight of 54 total unsolved homicides between the years 1970 and 2006 within the jurisdiction of the Sonoma County Sheriff's Office. In 2011, cold storage DNA from some of the cases was submitted to Combined DNA Index System (CODIS), a national DNA database.
