Wife claims firefighter husband was in 'manic episode' before she killed him. Cops say it was murder.

A 911 caller reported that her husband fell and was unconscious. 

But, when police arrived at their Massachusetts home, they found the woman and her teenage daughter standing over the victim. Authorities say it wasn't a fall that killed the victim, but murder. 

Plymouth County District Attorney Spokeswoman Beth Stone told the Patriot Ledger that Christine Ricci, 46, stabbed her husband at least two times with a 5-inch knife on Jan. 28 in their home.

Michael Ricci, 51, suffered from two stab wounds  — one on the left side of his chest and the other in the left back shoulder, according to authorities.

Stone told the newspaper there was an argument before the stabbing.

According to the Patriot Ledger, Assistant District Attorney Shanan Buckingham said police interrogated Christine Ricci and she stated her husband was in a manic episode, grabbed her by the throat, threw her to the ground and lunged at her after she grabbed a knife and she had no idea he was hurt until he fell to the ground.

Buckingham added there were prior physical and verbal incidents at the couple’s house and Christine was identified as the aggressor at the time, including a time that she lunged at her husband with a knife.

The Patriot Ledger reported a Plymouth County grand jury indicted Christine on one count of murder for her husband’s death, as well as one count of assault and battery by means of a dangerous weapon.

No arraignment date has been set yet for her first appearance in superior court, authorities said.

According to his obituary, Michael Ricci was born in Boston and served as a firefighter in the city for 23 years after leaving the Army, where he served in the Gulf War. Michael leaves behind three children.
