24 years later he confessed to her murder, but Annette's body has never been found.

Annette Hill (Annette Cundiff)

She was a 38 year old social worker when she went missing from Sandy, Utah on May, 12, 1989.

She left her home near 82nd South and 1220 East, telling her 11-year-old daughter she would be back in a couple of hours, and never returned.

Annette took her purse with her when she disappeared, but left behind her vehicle.

As a part of a plea deal, Thomas Evan Noffsinger, who had been in prison for 24 years for killing a chef admitted on Friday, October 3rd, 2014, that he murdered a teenage girl in 1989 and also confessed to killing Annette a month later.

Her purse, which had blood on it, was discovered in an apartment that Noffsinger had been evicted from.

Police also found a prescription bottle with Hill's name on it in Noffsinger's medicine chest.

Noffsinger sad that Annette had stopped to use a pay phone near 900 E. South Temple in Salt Lake City. 

Noffsinger was riding his bicycle home from a bar when he saw Annette and stopped to talk to her.

He doesn't know what made him do it, but he hit her and dragged Annette's unconscious body behind a gas station.

He returned to retrieve his bike, and then went back to strangle Annette until he could tell she was dead.

He then sexually assaulted her and put her body in a nearby Dumpster, covering her with trash.

Her body has never been found.

Annette's loved ones obtained a death certificate for her in 1991.

At the time of her disappearance she was 5'4 - 5'5 tall, 110 lbs, with strawberry blonde hair, red highlights and blue eyes.

She had pierced ears and freckles.

She was wearing a black jumpsuit, black shoes, a peach-colored ring, and a gold-colored watch.
