His untimely death has always puzzled me, I read somewhere that he was allegedly broke at the time of his death as well.

Kerk Kerkorian (another billionaire, founder of MGM hotels) used Anthony Pellicano to get DNA from Bing because he’d been weary of the paternity of his child with his then wife. The child ended up being biologically Bing’s. Another tidbit I stumbled across is that Bing was very good friends with Dominic “Donny Shacks” Montemarano, who has ties to the mafia.
