Summary based on the NamUs case record (MP8606) and 6 other sources
Cynthia Lynn Maine, a 26-year-old woman, was last seen on February 21, 1986, in San Diego, California. At the time of her disappearance, Cynthia was on probation after being released from jail for writing bad checks. She had a history of heroin addiction and worked as a police informant, which has raised suspicions about her case. On the day she went missing, Cynthia told her family she was going to see a movie but never returned. She contacted her mother two days later, but that was the last time anyone heard from her.

Cynthia's car was found abandoned six weeks later in the parking lot of a restaurant in La Mesa, California. Inside the vehicle, her personal belongings, including her purse and jacket with cash, were discovered. Cynthia had been romantically involved with a police officer and was providing information on other officers, making her disappearance more complex. Several other women connected to the same officer and similar circumstances were found murdered around the time she vanished, intensifying the suspicions surrounding her case.

Cynthia's case remains unsolved, though she has been declared legally dead, and foul play is strongly suspected. Investigators continue to seek any information that could bring closure to her family.
