Nancy Guthrie Tip Leads Searchers to “Killing Field” Across Mexico Border | 131 Days Missing

A chilling new tip has pushed the Nancy Guthrie case across the border and into one of the darkest possible search areas yet. After 131 days with no sign of the missing Arizona grandmother, a volunteer search group in Nogales, Mexico says it received a specific anonymous tip claiming Nancy Guthrie may be buried near Mariposa, an area where searchers have previously found 25 unmarked graves. In this episode of Drop Dead Serious, Ashleigh Banfield breaks down the new Mexico search, the anonymous tip, the 25 unmarked graves, the Pima County response, and then sits down with Dr. Tracy “Trace” Sargent, a forensic criminologist, victimology expert, law enforcement officer, canine handler, and missing persons specialist, to talk about what this tip could mean.
