ELGIN, Ill. (STMW) — An Elgin woman is charged with first-degree murder after allegedly hitting her boyfriend in the head with a frying pan during an argument in the home they shared.

Nora P. Peterson, 34, allegedly hit her live-in boyfriend Michael N. Mielczarek, during an argument Saturday at their apartment in the 100 block of South State Street, according to Elgin police.

She allegedly hit him in the head with several items, including a frying pan, causing the 55-year-old man to fall and hit his head on the floor, according to a release from police.

Officers responded at 3:47 p.m. after he stopped breathing and Peterson called 911 for an ambulance, the release said. Paramedics took him to Provena Saint Joseph Hospital in Elgin, where he was pronounced dead.

Police would not comment Monday night on what sparked the fight.

An autopsy Monday found Mielczarek died of blunt force trauma to the head, the release said.

Peterson was charged with one count of first-degree murder in connection with his death, and will appear in bond court Tuesday at Elgin Branch Court, 150 Dexter Ct. in Elgin.
