It isn't clear what led law enforcement agents to a man named Roy Eubanks in Mineola, Texas, or whether he had a lawyer. But in a statement, U.S. marshals say the 78-year-old admitted his real name is Joseph Lewis Miller.
Miller is charged with fatally shooting a man in a parking lot next to a Harrisburg hotel in January 1981.
Marshals say he also served 11½ years in prison for another murder and was released in 1971.
The marshals say he's being held in Wood County, Texas, pending court proceedings that would lead to his return to Pennsylvania.
