His grandson Shaun found him .He is 8 and all he could say was pop pop left me and I am mad at him .The autopsy is schedualed for tomorrow .They listed as homicide until the report comes in .They found him on the living room floor .So far they think it was a massive heart attack but until tomorrow ,we are not sure .He was always a healthy person and gosh he loved his grandson and he lived with him also .Shaun's parents are a mess since they were in divorce proceedings .I am at a lose of what to think .Thank you all ,I have been on the phone for hours now .He was such a great guy ,he raised his son by himself and now was raising his grandson .just lost lately .
