Molina was last seen in Tucson, Arizona on August 10, 1993. On the night of August 9 - 10, she and two female friends went out for the evening. They separated at Sunny's Pub in the 5400 block of south 12th Avenue. She got a ride with two men at 12:30 a.m. on August 10, and they stayed up all night. They went to Terry & Zeke's Bar in the 4300 block of east Speedway.

When questioned later, one of Molina's companions said he'd dropped the other man off and went for a drive with Molina. During this time she called the fast food restaurant she worked at and said she would not be coming in that day. Molina's companion said he last saw her when he dropped her off at a convenience store at south Park Avenue and east Ajo Way at 10:00 a.m.

Later that day, a woman found Molina's purse, containing a small amount of cash, was found on the roadside near west Ajo Way and south Comanche Road, about fifteen miles west of downtown Tucson. This was the last sign of her; she has never been heard from again. Foul play is suspected in her disappearance, which remains unsolved.
