Michael McCollum is the guy. His dad was a hardcore biker and outfit associate. Book hopefully coming by end of year. He apparently grew up in the life, both biker and outfit, eventually was the Sargeant At Arm's for Chicago Hells Angels during the war years (90's).

Was ordered to kill his best friend Mel Chancy and quit instead. Then went back to outfit side of things and started robbing area 81 guys. Went to prison, at some point actually became Outlaws Gary Indiana president.

Hopefully it's well written. This podcast has a few episodes with him, audio sucks on this one.
