According to Nashville, Tenn., station WZTV, a person who appeared to be an employee of the haunted house approached Greenfield’s group after they had already visited the attraction and were playing carnival-type games.

The alleged employee, in character, asked Greenfield whether another person in her group was teasing her, and when she playfully answered “yes,” handed Greenfield what she believed was a prop knife, saying, “Well here, stab him.”

According to the Tennessean, Greenfield then stabbed the victim, James “Jay” Yochim, in the arm. She even jokingly said, “Ha-ha, gotcha!”

It wasn’t until Greenfield pulled the knife back that the group realized it was a real weapon. Blood started to pour from Yochim’s forearm. “His arm was gushing blood like something out of a horror scene,” Greenfield said. She added that the suspected employee ran away.
