The 1992 conviction, which was upheld on appeal in 1996, hinged on expert testimony, included claiming an impression of Krone's teeth matched bite marks found on the victim's body, a detail that was disputed by dental experts called by the defense in court.
On April 8, 2002, Krone was released from prison after DNA evidence proved that he did not murder the victim and identified the killer: Kenneth Phillips, a repeatedly violent sexual offender.
Journalist Robert Nelson later wrote that ample crime scene evidence and interviews should have excluded Krone as a suspect, and all pointed toward Phillips, but this data were ignored by the police and the prosecution's purported experts.
[6] Since Krone's release, he has become an activist working for the abolition of the death penalty, and he is the director of Membership and Training for Witness to Innocence.
His story is detailed in Jingle Jangle: The Perfect Crime Turned Inside Out, written by Jim Rix, his cousin, who was instrumental in getting him freed from prison.
