Oklahoma police now have a confession from a man that he had sexually assaulted more than a dozen women from four different states. One was a student at Texas Tech. Robert Bruce told police last month that he raped women in Colorado, New Mexico, Oklahoma and Texas. Bruce already is serving time in a Colorado state prison after being convicted for attempting to kill a police officer.

Police say Bruce found his victims by hanging around college campuses, where he knew he could find women and follow them home. Once he was at their house, he would use elaborate means to get inside their bedrooms, including disabling motion detectors and cutting through windows. Bruce became known as the 'Ether Man' because he would knock women out with chemicals before sexually attacking them. His assault on the Tech student occurred in 2005. KAMC-28 located the woman, who chose not to be identified.
