Summary based on the NamUs case record (MP5422) and 6 other sources
Mona Lisa Lincoln, 20 years old at the time, was last seen on June 21, 1987. She had left her parents' home in San Diego, California, with the intent of cashing a check. Mona took a bus to Inglewood, California, and has not been heard from since. Notably, the check she intended to cash was never processed, adding to the mystery surrounding her disappearance.

Mona, who sometimes went by the name Monica, is described as 5'5" tall, weighing around 100 pounds, with brown hair and brown eyes. She has distinctive tattoos, including one of the Virgin Mary on her right shoulder and another on her knuckles. Despite efforts to locate her, very few details have emerged, and her case remains unsolved. Authorities continue to seek any leads that could help resolve what happened to Mona that day.
