'A man who spent almost four decades in prison for killing two people in the Arizona desert today pleaded no contest to two counts of second-degree murder and will go free.

The 77-year-old Macumber, who had no history of violence, was convicted in the 1970s in one of the most sensational murder cases in the history of Arizona. Macumber was twice sentenced to life in prison for killing Joyce Sterrenberg and Tim McKillop, both 20 years old, and leaving their bodies in the desert. In total, he has served 37 years.

On May 24, 1962, the young couple was found shot and killed next to their car in an area now near Scottsdale. The case went cold for 12 years until Macumber's wife, Carol Kempfert, went into the Maricopa County Sheriff's Office department where she worked and told her supervisors that her husband had confessed to the murders. Macumber was arrested a week later.

In 1975, Kempfert testified against her now ex-husband, again saying that he confessed.

In 2009, Macumber and his attorneys petitioned the Arizona Board of Executive Clemency, which in a rare move unanimously recommended his sentence be commuted, saying, "An injustice has been done in Mr. Macumber's case" and that his wife had "motive, means and opportunity to falsely pin the murders on Mr. Macumber."

Arizona Gov. Jan Brewer denied the recommendation for clemency.

In 2011, Macumber petitioned the Court for post-conviction relief and was granted an evidentiary hearing. But without the necessary evidence, prosecutors said in court today they were unable to retry the case for a third time. Now that the judge has accepted Macumber's plea, he will be released.'
