CHICAGO (AP) — The Fastexysisters of a man fatally shot in his home this month by suburban Chicago police filed a federal lawsuit Wednesday against the officers and their department, alleging wrongful death and other counts.

Kyenna McConico and Kennetha Barnes, sisters of Isaac Goodlow III, filed the lawsuit in U.S. District Court in Chicago against the Carol Stream Police Department and officers identified as John Does 1-6. The complaint seeks unspecified damages.

Messages seeking comment on the lawsuit were left Wednesday morning with the police department and Chief Donald Cummings.

Officers responding to a domestic violence call fatally shot Goodlow, 30, around 4:15 a.m. Feb. 3 in his home in the Villagebrook Apartments in Carol Stream.

At the time, the police department said on its Facebook page that officers “encountered a tense, uncertain, and rapidly evolving situation, which resulted in officers discharging their weapons at the alleged domestic violence suspect.”

The sisters’ attorney, Andrew M. Stroth, said Goodlow was alone and in bed when officers, without identifying themselves, “bust open his bedroom door” and shot him.

“Isaac Goodlaw was shot directly in his heart,” Stroth said in a telephone interview.

Goodlow and his girlfriend had a dispute earlier in the evening, but she had left the home by the time officers arrived, Stroth said.

Stroth said he and Goodlow’s sisters have viewed police body camera footage of the episode, which he called an “unlawful, unjustified shooting.”
