Annette Hill, 38, left her Sandy, Utah condominium on the evening of May 12, 1989, telling her young daughter she would be back in a couple of hours. She left her car in the carport and was last seen wearing a black jumpsuit, black shoes, a gold-colored watch, and a peach-colored ring. Her night included visits to Club 90 in Sandy and the Zephyr Club in Salt Lake City before she reportedly went to the Avenues-area home of a man she had met; that man was later cleared as a suspect.

About ten months later investigators tied Annette to apartments rented by Thomas Evan Noffsinger, also known as Thomas Trujillo. In one former residence they found Annette’s black purse stained with blood and containing her driver’s license; in another apartment they recovered a prescription pill bottle bearing her name.

In October 2014 Noffsinger, already serving life for the 1990 murder of Victor Aguilar, confessed as part of a plea deal that he killed Annette: he said he encountered her by a pay phone near 900 East South Temple, struck and then strangled her behind a nearby gas station, sexually assaulted her, and disposed of her body in a dumpster. Her remains have never been found. If anyone knew Annette, her movements that night, or saw her after she left home, please come forward with information.
