A Staten Island woman who bludgeoned her husband to death with a crowbar before setting their house on fire pleaded guilty Monday to first degree manslaughter.

Antoinetta Baldassarre, 69, left her 80-year-old husband, Frank, lying dead in the bathtub in October of 2014 before setting a blaze in their garage and bounding herself to a chair in attempt to simulate an arson, according the Staten Island District Attorney’s Office.

“This defendant has pled guilty and will be held accountable for the violent and brutal crime she committed,” the Staten Island DA, Michael McMahon, said in a statement.

The wife told cops at the time that she was “sick and tired” of her husband abusing her, a law-enforcement source said.

She was discovered with her feet and mouth bound with duct tape.

The woman faces 15 years in prison.
