A retired detective believes the key to solving the Nancy Guthrie case may already exist, buried under thousands of tips that investigators are still working through.
Retired Modesto Police Department detective Jon Buehler, who previously worked the high-profile Laci Peterson case, thinks the person behind the crime may have made a simple digital mistake.
He believes if the suspect searched for Nancy Guthrie's address on Google Maps or another navigation service before the alleged abduction, those records could still exist and potentially help investigators identify them.
Buehler also suggested newer vehicles with built-in tracking technology could provide another clue, allowing investigators to identify vehicles that were near Nancy Guthrie's home around the time she disappeared.
The retired detective drew a parallel to the 1999 Yosemite killings case involving Cary Stayner, where a hand-drawn map sent by the killer went unnoticed for several days because it was lost in a pile of mail.
He noted that fear can keep cases cold for years and believes only one person carried out the abduction, pointing to the large reward offered in the case.
