Kim Allen's body is found off Enterprise Road
Allen's body was found in a creek bed off Enterprise Road near Glen Ellen. Investigators concluded she had been sexually assaulted, bound, and strangled.
View sequence of events
Investigators recovered physical clues including a gold loop earring and biological evidence.
Her dumped body established the rural Sonoma County disposal pattern that later cases would echo.

Jeannette Kamahele disappears near the Cotati on-ramp
Santa Rosa Junior College student Jeannette Kamahele was last seen entering a pickup truck near the Cotati Highway 101 on-ramp. She has never been found.
View sequence of events
A witness described the truck as an older pickup towing or carrying a faded homemade camper.
Her disappearance remains one of the strongest possible but unconfirmed links to the broader series.

Lori Lee Kursa disappears in Santa Rosa
Lori Lee Kursa, 13, disappeared during November 1972 after a period in which she was known to run away and hitchhike around Santa Rosa.
View sequence of events
Lori was known to run away and hitchhike, which meant her disappearance did not initially trigger the level of emergency response a stranger-abduction case might have received.
That delayed urgency mattered because she vanished into the same roadside ecosystem already producing dead and missing girls around Santa Rosa.

Lori Lee Kursa is found in a Calistoga Road ravine
Kursa's body was discovered about 50 feet down a ravine off Calistoga Road. Investigators believed she had died one to two weeks before the discovery.
View sequence of events
Cold weather preserved the body enough to narrow the likely time of death.
Her death deepened the pattern of teen girls disappearing and being dumped in isolated Sonoma County terrain.

The remains of Sterling and Weber are found off Franz Valley Road
Hikers found the skeletal remains of Maureen Sterling and Yvonne Weber down a steep embankment off Franz Valley Road nearly ten months after the girls disappeared.
View sequence of events
The skeletal remains were found down a steep embankment off Franz Valley Road, nearly ten months after the girls vanished.
No clothing was recovered with the bodies, reinforcing the recurring dump-site pattern that linked the case to the other Sonoma County killings.

Carolyn Davis leaves home and begins drifting through Northern California
Fifteen-year-old Carolyn Davis left home in Anderson and moved through multiple Northern California stops before eventually returning toward the North Bay.
View sequence of events
After leaving home in Anderson, Davis moved through Northern California in the same hitchhiking and runaway circuits that had already become dangerous for young women and girls.
Her drifting path matters because it shows how the case intersected not only with local Santa Rosa teens, but with a wider youth mobility pattern across the region.

Carolyn Davis is found near the Sterling and Weber recovery site
Carolyn Davis's remains were found just feet from where Sterling and Weber had been discovered. The coroner determined she died of strychnine poisoning.
View sequence of events
The body location linked her death physically to the most symbolically important dump site in the case.
Her cause of death added complexity to the question of whether a single offender or more than one killer was operating.

Therese Walsh is last seen hitchhiking north before Christmas
Therese Walsh was last seen attempting to travel north for the holidays. Days later, she would become one of the most violently treated victims associated with the case.
View sequence of events
Walsh was older than most of the earlier victims and was traveling a much longer intercity route when she disappeared.
Her case widened the pattern beyond local teens by showing that adult women moving through California's hitchhiking network could also be pulled into the same zone of danger.
Dec 28, 1973
Therese Walsh is found in Mark West Creek
Walsh's body was found in Mark West Creek after heavy rains. She had been sexually assaulted, hogtied with clothesline, and strangled.
View sequence of events
Investigators believed the body may have floated several miles from the original dump site because of storm runoff.
The rope binding and body disposal intensified theories about a serial offender with a stable signature.

Investigators and later writers treat the murders as part of a wider Northern California pattern
By the mid-1970s, investigators and later chroniclers were openly considering whether the Santa Rosa killings were linked to a wider cluster of hitchhiker murders across Northern California.
View sequence of events
By the mid-1970s, investigators and later writers were no longer treating the murders only as isolated Sonoma County events.
The possibility of links to a broader Northern California pattern made the central question harder: was this one offender, several offenders, or a partially overlapping cluster of cases?
Jul 2, 1979
An unidentified Jane Doe is found near the Kursa recovery site
The skeletal remains of an unidentified young woman were found near Calistoga Road close to where Lori Kursa had been discovered years earlier. She remains unidentified.
View sequence of events
The unidentified young woman's remains were found close to the area where Lori Kursa had been discovered years earlier.
Because the estimated time of death overlapped the original active years of the series, the discovery reopened the question of how many victims might truly belong to the Santa Rosa pattern.

Kerry Graham and Francine Trimble are identified in a separate but often-compared case
DNA identified the remains of Kerry Graham and Francine Trimble in 2015. Their murders remain separate and unsolved, but the pair are still discussed around the Santa Rosa case because of geography and victim profile overlap.
View sequence of events
DNA work finally gave names back to two long-unidentified North Bay victims whose case had often circulated near Santa Rosa discussions.
Even though their murders remain separate, the identification highlighted how many nearby Northern California victim clusters had been left unresolved for decades.
