Miranda Barbour picked up LaFerrara at a mall in Selinsgrove on Nov. 11 and drove in her car to Sunbury, a small city about 100 miles northwest of Philadelphia.
After they parked, Elytte Barbour came out of his hiding place under a blanket in the back seat and held a cord tight against LaFerrara's neck while his petite wife stabbed the 6-foot-2, 278-pound man about 20 times. They dumped his body in an alley.
Elytte Barbour later told police the couple killed LaFerrara, who was 42, because they wanted to kill someone together.
