Slain wife’s horror scream

A jealous husband stabbed his beautician wife so forcefully inside her Garment District hair salon that his knife broke into three pieces, a Manhattan murder jury learned today.

“No! No! No!” victim Denise Kenny screamed as she died, a salon worker told jurors, who watched grim-faced as they viewed crime- scene photos showing the West 35th Street salon’s blood-splattered bathroom.

“And then from there, I heard just screams — muffled screams,” stylist Gennaro DeMarco told jurors of the March 2011 attack at the D’Galina’s Center between Seventh Avenue and Broadway.

Michael Kenny, 42, of Rockaway Park, Queens, deserves a break for mentally “snapping” over his wife’s infidelities, and be convicted only of manslaughter, defense lawyer Kevin Canfield argued in his opening statements.

The husband lost his mind after his wife sent a topless photo of herself to his cellphone — later admitting that the intended recipient had been her ex-husband in Trinidad, the lawyer told jurors.

But prosecutor Linda Ford told jurors in her own opening statements that the husband came to the salon prepared for revenge — bringing a six-inch kitchen knife — and rifled the cash register before fleeing.

Kenny has a long history of robberies, violence, and drug issues. Testimony continues Wednesday.
