John Mitchell Kinsora was last seen between 3:00 and 4:30 a.m. on February 26, 1982, at a party at an apartment in the vicinity of the 4200 block of north 17th Street in Phoenix, Arizona. He and a friend had gone to a rock concert that evening and afterwards, three men that he knew invited him to go to the party, which was hosted by two women at their apartment. According to the other guests, Kinsora and his friends asked if they could spend the night at the apartment, since they were all too drunk to drive. Most witnesses agreed that Kinsora made advances to one of the women and her boyfriend asked him to leave, so he decided to hitchhike home. He never arrived at the Tempe, Arizona home he shared with his parent and has never been heard from again.
