John Mitchell Kinsora was 19 when he disappeared from Phoenix in the early morning hours of February 26, 1982. He had attended an AC/DC concert and became separated from a friend, later meeting three acquaintances who invited him to an after‑party near the 4200 block of North 17th Street. He was last seen at that gathering between 3:00 and 4:30 a.m.

Descriptions list him as a White male with brown hair and brown eyes, about 5 feet 7 inches to 5 feet 9 inches and 135 to 145 pounds. He wore a black and brown checkered flannel shirt, a gray Bob Seger T‑shirt with blue sleeves, and light brown corduroy pants. Notable marks included a small scar under his right eye and burn marks on his left forearm.

Witnesses said he was too intoxicated to drive and asked to stay at the apartment but was told to leave after he made advances toward a woman; her boyfriend apparently asked him to go. John then reportedly decided to hitchhike back to the Tempe home he shared with his parents and never arrived. He had just taken a job at a phone company, planned to move into an apartment with a friend, and left behind his last paycheck. The Phoenix Police Department continues to list him as missing. Does anyone have information about John’s movements that night or the area around North 17th Street in February 1982?
