Deborah Suzzette Hernandez Moberg was 18 and a MacArthur High School senior when she disappeared from San Antonio on January 9, 1987. Her disappearance began two days earlier when her stepfather, Ray Moberg, abducted her from the family home and also took her eight-year-old half-sister, releasing the child at their grandmother’s house the next day. Deborah was never seen again.

Ray Moberg was arrested on January 11 at a motel on a charge of aggravated sexual assault of his biological daughter. Investigators found 94 photographs in his motel room showing naked young girls and a man engaged in sexual activity. After six months of silence he confessed to shooting Deborah and disposing of her body in a dumpster; despite extensive searches her remains have not been found. He later pleaded guilty to Deborah’s murder and received life in prison, along with additional sentences for burglary and sexual assaults tied to images in that motel room.

Deborah’s half-sister told police that during her captivity Moberg was driving Deborah’s red Ford Mustang and stopped near a body of water with cattails and telephone poles, where he dropped something from the back of the car. Searches based on that lead have been fruitless. Does anyone have information about Deborah, that Mustang, or locations matching the half-sister’s description?
