Whatever the facts of him being beaten are, he was a career criminal. Could be one of his past victims took him out:
“Raynor had 24 arrests to his name, but his record did not suggest a history of pedophilia, sources said.”
Whatever his merits or demerits, at this point what difference does it make? He’s dead. No trial. No evidence presentable at a trial. No right to counsel or appeal. Just a couple of gumbahs with baseball bats or crowbars. Too late to presume he’s innocent even.
