Iris Leslie Brown was 27 when she was last seen in Burlington, Vermont, on March 15, 1976. Described as a White woman with dark brown hair and hazel eyes, about 5 feet 4 inches and 127 pounds, she was reportedly wearing a long green wool coat and blue jeans. She left her apartment with William John Posey Jr., who said he would drive her to Connecticut to see her boyfriend, Martin Gold, then incarcerated on drug charges; Iris never arrived in Connecticut and was never heard from again.

Investigators grew to believe Iris had been killed and Posey became the central suspect. Blood matching Iris’s type was reported in Posey’s car. In 1981 Posey was convicted of kidnapping her and given a life sentence; in 2008 he confessed to causing her death, saying he had strangled her after an argument and disposed of her body along Interstate 89 in Vermont but could not give a precise location. Her remains have not been found and the case remains listed as a missing person in NamUs.

Iris grew up in Enosburg Falls, Vermont, graduated from Enosburg Falls High School and attended the University of Vermont. Does anyone have information about Iris’s movements in March 1976 or recall seeing a long green wool coat in the Burlington area that day?
