Idaho cold case: Challis missing person identified at last
Idaho investigators have solved the decades-old missing person case of Lois Ford, a Challis woman last seen in 1983. Custer County detectives traced her to Boise-area records and identified her remains from a 1993 Ada County coroner's case, restoring her name after more than 40 years.
Key Takeaways
- Lois Ford vanished from Challis in 1983 with her 1978 Ford Thunderbird and was never formally listed as missing until 2025.
- Handwriting analysis of 1992 Ada County court records showed she was alive in the Boise area nearly a decade later.
- Detectives linked her to a 1993 Ada County Coroner's Office case; she had been buried under an alias.
- Family members positively identified her remains, ending more than 40 years of uncertainty.
What happened to the Challis missing person?
Lois Ford was about 40 and last known to be living in Challis when she disappeared in 1983. Her 1978 Ford Thunderbird was never located. Relatives searched for years with help from law enforcement and private detectives, but found no credible leads. Theories once included an undiscovered crash into water, officials said.
Confusion among family members meant Ford was never officially reported as a missing person. That gap left her case outside national databases for decades.
How did investigators crack the cold case?
In 2025, relatives contacted the Custer County Sheriff's Office and asked for another look. The file went to Dave Walls, the office's records and evidence supervisor with prior cold-case experience. He entered Ford into a national missing persons database and enlisted Idaho State Police investigator Karl Noah.
Together they reviewed hundreds of unidentified remains cases in Idaho, Oregon, and Nevada, contacted coroners across the West, and searched historic crash records and genealogical databases. The breakthrough came in 1992 Ada County court records under a name similar to Ford's. Handwriting analysis indicated the signatures were likely hers—proof of life in the Boise area in 1992.
Walls then worked with Ada County Sheriff's Detective Tim Cooper, who found additional Boise Police contacts under several aliases. That trail led to a 1993 Ada County coroner's case, as reported by KTVB. Case files and scene photographs convinced Walls the woman was Ford; family members later confirmed the identification.
Why does this missing person resolution matter?
Investigators said Ford was experiencing homelessness at the time of her death and may have been struggling with mental illness. Unable to locate her family in 1993, authorities buried her under an alias. Her children and grandchildren have now reclaimed her remains and restored her name.
The Custer County Sheriff's Office thanked Cooper and Noah for helping close the decades-old disappearance, giving Ford's family long-sought answers in one of Idaho's longest-running mysteries.
