As the Nancy Guthrie investigation enters its fifth month with no updates on suspects, a retired detective has spoken about how a careless mistake made by the perpetrator could lead to the case being solved.

Retired Modesto Police Department detective Jon Buehler, who worked on the Laci Peterson case, recently spoke with NewsNation’s Brian Entin, who has been closely following the Nancy case from the start. Buehler suggested the case could still be cracked, noting that newer cars have tracking capabilities.
