Dorothy Ann Bois was 22 when she disappeared from her Kinsley Street apartment in Nashua, New Hampshire. She was last seen the night of October 3, 1973; her husband, Kenneth Bois, says the couple had been watching television and he fell asleep about 11:30 PM. When he awoke later, Dorothy was gone and Kenneth reported her missing in the early hours of October 4.

Dorothy was described as 4 feet 10 inches, about 100 pounds, with brown hair and hazel eyes. She was reportedly wearing an orange bodysuit, blue jeans with paisley bands around the knees, and brown clogs. Searches and interviews were conducted but produced no significant leads, and the circumstances of her disappearance remain unexplained. Some have speculated about possible foul play, but no evidence has conclusively determined what happened.

Anyone with information about Dorothy, her last known movements, or the Kinsley Street area on October 3–4, 1973 is asked to come forward.
