Jim, for the past 35 or so years I've known boyfriends of Keating and plain close friends. His suicide was common knowledge and they often stated that Keating finally did it after 5 or six tries. He lost a lot of money at Scarborough Fare and made other poor investments. He owed Dr Ben Braude money for the dental work he received. I could go on and on about him.
The newspapers commonly state a heart attack when other info is not readily developed or investigated. You see, when we all die, we suffer heart failure. If you want to believe he didn't slash himself....that's ok with me.
