Fifty years ago Joyce Sterrenberg and Tim McKillop were murdered in Scottsdale, Arizona. In 1974, 12 years after the murders, a sheriffs department employee told the police that her estranged husband, Bill Macumber, confessed to her. Macumber, besides being a single father of three, was an army veteran, Little League coach and a member of the Sheriff's Search and Rescue Posse. Bill was tried and convicted in 1975, based mostly on fingerprint evidence. But, the jury never heard about the confession of a drifter who confessed to the murder several years earlier. And, there are suggestions that his ex-wife tampered with the evidence in the old case file that she had access to at the sheriff's office. Macumber, now 76 years old, has served 35 years of his two life setences. The Arizona Justice Project, assisted by private investigator Rich Robertson of R3 Investigations, has been working on his case for nearly a decade. The Arizona Executive Board of Clemency recommended his sentence be commuted, but that was rejected by the governor. Tune in to hear Rich Robertson’s journey into the depths of this old case and how The Justice Project pulled the facts together.
