I believe Joe Coffey is the one that started that rumor. That John himself did it. But it's been verified that he was in Florida to have an alibi. Plus, I don't think anyone has even claimed that Gotti ever actually killed anyone personally, let alone chopping a guy chained to a radiator to death with a chainsaw. Ha. No doubt he gave the OK to have it done and knew when it was happening so he took a trip to FL while his goons carried it out.

Has Sammy ever talked about this on his podcast/YT channel? I know he talked about how John gave Willie Boy Johnson his word on this son's grave that he wouldn't be killed, but later on changed his mind and had him machine gunned to death.
