More than forty years after 13-year-old Sarah Ann Geer was found dead in a downtown Cloverdale alley, a Sonoma County judge on Friday ordered 64-year-old James Unick to spend the rest of his life in prison, finally closing a case that had haunted the small city for decades.
Judge delivers sentence
Yesterday, Judge Laura Passaglia imposed a life term and told Unick that he had robbed a child of her potential, of her life and caused her to suffer in a most brutal way, according to The Press Democrat. The sentence followed a jury finding that a special circumstance involving a sexual assault was true.
Verdict caps monthlong trial
After a monthlong trial, a Sonoma County jury needed roughly two hours on Feb. 13 to convict Unick of murder, along with committing a lewd or lascivious act and raping a child, according to SFGATE. Prosecutors said the verdict delivered long-awaited justice to Geer’s family and closed what officials described as the county’s oldest cold case to reach trial.
How DNA and genealogy cracked the case
Prosecutors said a California Department of Justice criminalist developed a male DNA profile from evidence in 2003, and investigators later used genetic genealogy to narrow the suspect pool to one of four brothers, a group that included Unick. FBI agents then conducted surveillance and collected a discarded cigarette, which testing showed matched the 2003 profile and DNA recovered from the victim’s clothing and other items, according to ABC News.
Defense, testimony and the jury’s decision
At trial, Unick testified that the 13-year-old had propositioned him at an arcade and claimed that any sexual encounter was consensual, while denying that he strangled her. Jurors rejected that account after hearing witness testimony and forensic evidence, according to reporting from SFGATE. The panel returned its guilty verdict on what would have been Geer’s 57th birthday.
Reaction and a measure of closure
Sonoma County District Attorney Carla Rodriguez called the conviction a testament to everyone who never gave up searching for Sarah's killer, and Cloverdale officials said the outcome brought long-sought closure for Geer’s family, according to ABC News. The Cloverdale Police Department reopened the investigation in 2021 and partnered with private investigators and the FBI to move the decades-old case forward, according to a report by The Sacramento Bee.
Legal notes
The jury found true special-circumstance allegations that prosecutors said included a lewd or lascivious act and rape of a child, findings that under California law expose a defendant to life in prison without the possibility of parole, court reporting shows. The case was prosecuted by Deputy District Attorneys Christina Stevens and Alex Fisher, with assistance from investigators and Cloverdale detectives, according to CSLEA.
Investigators say the breakthrough began when the California Department of Justice developed the male DNA profile in 2003 and, after genealogical research and surveillance, culminated years later when agents recovered the discarded cigarette that confirmed the match and led to Unick’s July 2024 arrest, according to Newsweek. The resolution brings long-sought answers to Geer’s loved ones and highlights how modern DNA techniques are reshaping cold-case work.
