Bimlesh Singh, 48, disappeared from her Moreno Valley, California, home on June 24, 1994. She left that morning to run errands and was last seen at a grocery store on Pigeon Pass Road. Singh briefly returned home, leaving half-eaten food — a noted habit — then left again around 10:45 a.m. and never returned; her family reported her missing the same day.

Singh was driving a gray 1989 Nissan Sentra. The car turned up 19 months later, abandoned and stripped near Matamoros, Mexico, about 300 miles from Moreno Valley. Investigators found no definitive evidence of Singh’s whereabouts at the vehicle. At the time she disappeared she had mental health problems, possibly Alzheimer’s disease, and experienced memory lapses that sometimes prevented her from recalling her address or phone number.

Two days after the disappearance the family received a collect call from someone claiming to be Bimlesh; the call disconnected before any conversation and was traced to a McDonald’s in Moreno Valley. The case remains unsolved. If anyone knew Bimlesh, saw her that day, or has information about the car’s discovery, please share what is known.
