The rumor was always that it was Stevie Mazzone and Johnny Chang, with Joey acting as the blocker in a car. I don't know if it was Anastasia or Capparella, but someone gave them a quote that Johnny Chang told Merlino "thank you for letting me do this. A brother for a brother." They certainly didn't worry about cops, they made sure he was dead. His son is still around South Philly, knocking around.
