The incident occurred in April 1978 when Parthemore was 21 and his co-defendant, Dale R. White Jr., was 23. Two men accosted the teenage son of a Hepzhibah, Ga., family outside a Ramada Inn room and forced him into the room at gunpoint.
The pair then robbed the family, sexually assaulted the two daughters, aged 15 and 17, and raped the 39-year-old mother, while forcing the husband and son to watch.
Parthemore pleaded guilty in August 1978 to first degree rape, first degree sexual offense and armed robbery.
Parthemore's attorney, Brooke Murdock, told Wright in November that what Parthemore wants is a deal, perhaps one that would result in his sentence being lowered.
Hauver, now retired, testified that the case was resolved with guilty pleas.
Now almost 40, Parthemore claims that there was a binding agreement with then Washington County Circuit Judge John Corderman to limit his sentence to one life term in exchange for Parthemore's testimony against the co-defendant.
White pleaded innocent to the charges against him and stood trial in Garrett County, where the proceedings had been moved because of pretrial publicity.
He was convicted and sentenced to four life sentences plus 100 years, according to court records.
White attempted suicide while in prison in 1984 and lapsed into a coma, according to Division of Correction information.
He was paroled in November 1985 to the Key Medical Center in Baltimore.
