Denham's family say Zeiders' allegations are absurd and that he would not be interested in masturbating on her lawn because he was gay.
"He never would have attacked anyone," the victim's sister Maureen Tourigian told the Tampa Bay Times. "Anyone who knows know him know that, and that he never would expose himself to a woman. He wasn't interested."
A witness reportedly told cops he saw Zeiders and her pals beating and kicking Denham, and that he heard the word "pedophile" used during the attack.
Dan Kane, Denham's life-long partner, believes the trio beat his companion to death after attempting to rob him and discovering he only had a few dollars in his pocket.
Kane rubbished the masturbation story, saying it would have been completely out of character for Denham, especially considering his sexual orientation.
