In 2005, a female victim reported to the Valley County Sheriff's Office that she had been sexually assaulted by an unidentified male. Deputies and detectives conducted a thorough investigation; however, the victim was unable to identify her assailant or provide a precise location of the incident.Biological evidence was collected from the victim, yielding a DNA profile of an unknown male suspect. Despite exhaustive efforts, limited leads were available, and the case ultimately became inactive.
In 2022, the Idaho State Police (ISP) received funding through a grant under the National Sexual Assault Kit Initiative (SAKI), administered by the Bureau of Justice Assistance. This initiative supports the application of advanced DNA technologies to analyze evidence from sexual assault kits, thereby enhancing the potential to identify and hold perpetrators accountable.
A multidisciplinary team from the ISP SAKI Cold Case Unit reviewed the DNA profile associated with this case. Utilizing forensic investigative genetic genealogy, they developed actionable leads. A detective from the Valley County Sheriff's Office pursued these leads over the course of approximately one year, which included travel to other states to collect additional DNA samples and conduct interviews.
These investigative efforts identified a person of interest. Although the individual had passed away many years earlier, subsequent DNA testing of family members conclusively established—beyond a reasonable doubt—that he was the likely perpetrator.
Detectives notified the victim, who expressed profound gratitude for finally obtaining closure after more than two decades without answers.
Valley County Sheriff, Kevin Copperi extends his sincere appreciation to the Idaho State Police and the dedicated members of the ISP SAKI Cold Case Unit. Their expertise and collaboration were instrumental in resolving this long-standing case, which would otherwise have remained unsolved.
