Andrew Pixley

According to genealogical research, Robert and Betty McAuliffe divorced sometime after the murders. McAuliffe remarried Charlotte Olivia Moon Branch and had a son, Jon David McAuliffe, born on January 21, 1974, in Chicago. Robert died on April 1, 1998, of a heart attack. Betty McAuliffe died on November 28, 2010. Susan McAuliffe married and had five children.

Pixley pleaded guilty to first degree murder for killing Debbie and was sentenced to death. He started laughing when the execution date was announced. Robert McAuliffe told him "laugh some more, you animal." Although an appeal was filed to change his sentence to life imprisonment, he said he did not want an appeal. He was executed by lethal gas at the Wyoming State Penitentiary on December 10, 1965. He took the longest time to die of any person ever executed in the Wyoming gas chamber. Until the execution of Mark Hopkinson in 1992, Pixley was the last person to be put to death in Wyoming.

On the night of August 7, 1964, Pixley broke into a room of the Wort Motor Hotel in Jackson, Wyoming, occupied by the family of Illinois Circuit Court Judge Robert McAuliffe, who were on vacation. McAuliffe and his wife were elsewhere in the hotel taking in a show. When they returned to their room, they found Pixley lying on the floor. He appeared to be drunk, but may have been feigning; McAuliffe said at the trial he had not smelled alcohol. McAuliffe grabbed Pixley and pinned him to the floor. Police officer James Jensen heard Mrs. McAuliffe screaming and rushed to the scene, where McAuliffe shouted "My God, this man has killed my babies."

Andrew Pixley (January 29, 1943 – December 10, 1965) was a convicted murderer from Dallas, Oregon. He was executed December 10, 1965, in Wyoming for the murder of two young girls in August 1964. He was the last person executed in Wyoming until 1992, and the first of only two after World War II.
