we re still waiting to find out the actual cause of death. thanks so much. joining us now, former assistant director for the fbi in new york, bill gavin, now vice-president of a global security firm. anybody who has seen the movie, the godfather, or the sopranos how a potential witness in a mob trial could show up dead before he has a command to take the stand. what are you hearing from your law enforcement sources? what might have happened? so difficult to tell. this case hays taken so men twists and turns. i don t think there s enough facts yet to support any kind of a conclusion. hot as can be in boston. did he have heat stroke, a stroke, heart attack? nobody knows but the coroner s office says there s no external manifestation of some gunshot wound or something like that. they have to do the autopsy.
