Cynthia Mabry was 13 when she disappeared from her Russellville, Arkansas, home on the evening of December 2, 1976. She was last seen about 5:30 p.m. wearing blue jeans and a beige three-quarter-length hooded coat with fur trim. Two other neighborhood girls, 13-year-old Teresa Williams and 14-year-old Crystal Donita Parton, also went missing that day.

In 1986 skeletal remains of Teresa Williams and Crystal Parton were found near Brock Cemetery in northern Pope County; both had been stabbed in the neck. Cynthia’s body was not recovered. In October 1998 authorities identified James B. Grinder as the prime suspect. Grinder, already incarcerated in Missouri for burglary and charged in a separate 1984 rape-murder, eventually confessed to picking up the three girls, driving them to the Brock Cemetery area, sexually assaulting and fatally stabbing Teresa and Crystal, and then taking Cynthia into the Ozark National Forest where he said he raped and beat her to death with a tire iron. He pleaded guilty to capital murder and received a life sentence. Grinder later sought a sentence reduction claiming his confession was coerced and that others were involved; that request was denied. Grinder later died in prison of natural causes; Cynthia’s remains have never been found.

Does anyone have information about Cynthia’s last known movements or places she might have been taken after December 2, 1976?
