BEAVER FALLS (AP) — A teenage girl described hearing her parents executed by two masked men during a preliminary hearing in the killing four years ago.

A daughter of Richard Warren Harper and Demetria Harper described how she and a younger sister were ushered into a basement room and heard their parents shot on the other side of the door in June 2008.

Fifteen-year-old Laniya Harper described the ordeal Wednesday during a preliminary hearing for Robert Burgess and Devon Shealey. The men are accused of killing the Harpers inside their Beaver Falls home in a drug dispute.

The then-11-year-old girl said she saw her parents tied up and heard a man demanding money before two gunshots.

Testimony is scheduled to continue Thursday.
