Alvin L. Quinn, 32, of Zion.

A Zion man pleaded guilty to involuntary manslaughter after his gun discharged, striking his pregnant wife in the head and killing her, during a scuffle with another man in Round Lake.

Alvin L. Quinn Jr., 32, of the 2200 block of Lewis Avenue in Zion, took a plea deal offered by prosecutors on Tuesday and pleaded guilty to one count of involuntary manslaughter of a family member, a Class 2 felony.

He will serve seven years in the Illinois Department of Corrections and receive 609 days of credit served while in jail.

As part of the plea deal, prosecutors dropped charges of involuntary manslaughter of an unborn child, aggravated battery with a deadly weapon, reckless discharge firearm and two counts of aggravated unlawful use of a weapon.

Quinn and his wife, Isha Windom, 25, went to their old home on December 11, 2018, in the 600 block of West Nippersink Road in Round Lake to retrieve some of their property left behind after moving.

Prosecutors said that Quinn and another man got into an argument inside the home. Quinn pulled a gun and a struggle ensued between the two men.

Quinn struck the other man with the gun and it discharged, prosecutors said. The bullet went through the front door and struck Windom in the head.

Paramedics transported the woman, who was 22 weeks pregnant, to Advocate Condell Medical Center in Libertyville.

Windom’s unborn baby died in the hospital a short time after the shooting and the woman died a few days later.

Quinn could be eligible for release after serving 50% of his sentence if he shows good behavior, according to truth-in-sentencing guidelines. He will also have to serve two years of supervised release after prison.
