A Bronx handyman found dead with taunting messages scrawled across his torso in red lipstick liked prostitutes — whom cops are eyeing as the prime suspects in his murder, according to law-enforcement sources.

Joe Fisher, 75, was discovered by a co-worker lying face-up on his kitchen floor Wednesday with the words “Who’s Bitch Now” written across his chest.

His shirt had been pulled over his head, and “XOXO” was scrawled repeatedly across his stomach.

A neighbor, Carmen Velez, said Fisher had no enemies — but frequently would be seen with “friends.”

“Everybody likes to have friends,” she said. “He’s a single man.”

Fisher had suffered severe trauma to the left side of his head and may have been dead since Monday, cops said.
