Prosecutors say Fullman was with Rogers when she contacted the boy and offered to meet him at the castle to return a pair of headphones. Once there, Rogers allegedly used a 4-inch pocket knife to stab the teen in the head, upper chest, armpit and hand.
After causing what Hamburg police called life-threatening injuries, Rogers allegedly fled the scene. It was not immediately clear whether Fullman remained, but authorities said another individual called police.
The victim was taken to Newton Medical Center, where he received eight staples to his head and 37 stitches, according to Sussex County Assistant Prosecutor Sahil Kabse. The courts have withheld the boy s name because he is a juvenile.
