Twelve-year-old Crystal Gayle Dittmeyer vanished from her family’s apartment complex in Oklahoma City on June 13, 1996. She was last seen about 5:30 p.m. near the Pick Wick Apartments swimming pool wearing a white t-shirt with a yin-yang design and red and blue embroidered patch, blue jean shorts, and a matching yin-yang necklace. She was described as a white female with brown hair and hazel eyes, 5 feet 4 inches tall, 113 pounds, with a scar on her forehead near the hairline.

Investigators focused on her stepfather, Benjamin Harry Crider Jr., after injuries on his arm and shoulder the day after Crystal disappeared drew scrutiny. A younger half-brother told police he had seen Crystal motionless in his parents’ bedroom the day she went missing and that his mother took him shopping before Crystal was gone. Bloodstains reported to match Crystal’s DNA were found in the apartment and in Crider’s vehicle. Crider later admitted causing Crystal’s death and pleaded guilty to manslaughter; he never disclosed where her remains were found.

Crystal’s body has not been recovered and key questions about what happened that day remain unanswered. If anyone knew Crystal, her family, or observed activity at the Pick Wick Apartments around June 13, 1996, please share information that might help locate her remains.
