Charlene Elaine Barrios, 26, was last heard from in late September or early October 1988 when she told her mother she was in Florida. No further contact followed, and her mother reported her missing in August 1990, creating a nearly two-year gap between the last known communication and the report. The delay and the vague last known location make establishing a timeline difficult.

Authorities in Oakdale, California, where the family lived, continue to investigate. Charlene was reported as between 5 feet 6 inches and 5 feet 9 inches tall, with brown hair and hazel eyes, scars on her right knee and leg, and a tattoo on her right shoulder. She was also known to use the alias Regina Lett, which has complicated efforts to trace her movements after that final contact.

There is no clear indication of foul play in the available details, and the case remains unsolved and cold with little new information. If anyone knew Charlene, knew her as Regina Lett, or has information about her whereabouts in late 1988 or afterward, please come forward.
