Destruction of his liver by alcohol must have spread to other organs.
Horrible way to die.
Not uncommon. Many alcoholics will go to any lengths to hide their alcoholism. RIP, David Cassidy.
Alcoholism is suicide on the installment plan. It is a spiritual malady that inevitably involves some degree of self-loathing that invites self-destructive behavior. If you have a problem, or think you have a problem....seek help.
