Amedee's family is vague in their comments, but he apparently died of a "social disease" which, considering the times, is believed to have been syphillis. The beating did happen, and for the reason that everyone knows, but it did not kill him.
I remember Denis personally, even though I was young. He died, if I remember correctly, right around my 11th birthday, which would have been 1989. He used to ask Joel and me to dance while he played fiddle, then he'd sign dollar bills and give one to each of us in exchange for a kiss on the cheek.
