DENVER (AP) — A former longshot Idaho gubernatorial candidate on trial in the 1984 killing of a 12-year-old Colorado girl wasn't even remotely considered a suspect to law enforcement until his obsession with the crime and incessant visits to talk with police about it provided clues that turned him into the suspect, prosecutors said Wednesday at the start of the man's trial.

Steve D. Pankey, a repeat longshot candidate, was arrested last year in the death of Jonelle Matthews. The girl's remains were found after her face appeared on milk cartons as one of the first missing children featured on them in an effort championed by former President Ronald Reagan. She had been fatally shot.
