According to U.S. Marshals, Miller was charged in the 1981 death of Thomas Waller in Harrisburg, Pa. The Patriot-News reported that Waller was found inside his car with a gunshot wound to his head. That was the second time Miller was accused of murder. He pleaded guilty in 1959 to killing a Harrisburg man and was given life in prison — a sentence commuted in 1971 by former Pennsylvania Gov. Raymond P. Shafer.
A spokeswoman for the Pennsylvania Board of Pardons said the agency could not immediately produce the records related to Miller’s 1971 commutation Monday.
It remains unclear how Miller got from Pennsylvania to Texas, or why he chose the town of Mineola, about 85 miles east of Dallas.
