The man who spanned the eras of Ali and Tyson, Trevor Berbick, was hacked to death in the courtyard of his hometown parish. The police haven't found the weapon, but the wounds look to be from a hatchet. What a way to go--attacked and killed in your own church courtyard.
Berbick was the last man to fight Ali and the first belt holder to fall to Mike Tyson, who knocked him out memorably in the second round. He was killed in his home in Portland, a small farming community in Jamaica where he had opened a gym and was struggling to become a boxing promoter.
A number of news sources are carrying the story. I read about it at the SF Gate.
