Pamela Ann Pedro was 17 and a high school senior when she vanished from Atwater, California, on the morning of September 13, 1982. She was dropped off at Atwater High School and was last seen using a payphone outside the school; witnesses heard her on the line but nobody has been identified as the person she called. Pamela never returned home and did not respond to a school page that day.

Her family reported her missing later that afternoon; a police report was not filed until 24 hours after she was first reported missing. Pamela was set to graduate early, enjoyed classical piano and practiced karate. At the time she wore braces and large-framed glasses. Some have suggested she might have run away, but there has been no evidence of her whereabouts, no use of her Social Security number, and no driver’s license applications tied to her name.

The case remains open with the Merced County Sheriff’s Office and age-progressed images have been circulated. Does anyone have information about Pamela’s last day at Atwater High or remember seeing her after she used that payphone?
