In May 1982, a 13-year-old girl left a friend’s house in downtown Cloverdale, California and never made it home. The next morning, the body of Sarah Ann Geer was found in a secluded area not far from where she had been walking. Forensic tools available at the time were limited, and the case stalled for decades, leaving her name tied to what became Sonoma County’s longest-running unsolved case.
In 2003, a DNA profile was developed from evidence collected in 1982, yet when it was entered into law enforcement databases, it produced no match and the case remained open.
Nearly twenty years later, in 2021, Cloverdale Police revisited the investigation with the help of a private investigator and federal agents. Using investigative genetic genealogy, the DNA profile was linked to one of four brothers, narrowing the focus.
In July 2024, agents collected a discarded cigarette believed to belong to 66-year-old James Oliver Unick, and testing later confirmed that the DNA matched evidence preserved from the original investigation, leading to his arrest on July 22, 2024.
Last week, a Sonoma County jury found Unick guilty in connection with Sarah’s death with prosecutors describing it as the oldest case ever presented to a Sonoma County jury. His sentencing is scheduled for April 23rd.
More than four decades after Sarah Geer vanished in downtown Cloverdale, advances in DNA technology finally answered a question that had remained open since 1982, bringing long-delayed justice to her case.
