STAMFORD, Conn. (AP) A Greenwich man has pleaded guilty to attempted murder in a baseball attack against his wife in their Greenwich mansion in September 2013.

Greenwich Time reports Michael DeMaio entered his plea Tuesday in Stamford Superior Court. He faces up to 10 years in jail when he is sentenced in March.

Supervisory State's Attorney James Bernardi said the Sept. 10, 2013, attack was about two weeks after Diane DeMaio served separation papers on her husband of 33 years.

The arrest affidavit says the 56-year-old Michael DeMaio struck her multiple times in the head and face with an aluminum baseball bat, leaving her in a coma with a severely fractured skull and brain damage.

The couple finalized their divorce In May and their mansion went on the market last April for $11.8 million.
