CHICAGO (AP) — The family of a man who’s a suspect in the killing of three people in Chicago is on the scene of his standoff with police. They are urging the man to surrender peacefully after he exchanged gunfire with SWAT officers.

Police spokesman Anthony Guglielmi says officers also used gas canisters Thursday to try to get the man to give himself up.

He’s being sought for questioning in the shooting deaths of three people Wednesday night in the West Englewood neighborhood.

The man fired on officers from a window, and SWAT members fired back. Deputy police Superintendent John Escalante says officers then saw the man run upstairs, but it was unclear whether he’d been struck.

Speaking to video cameras outside, Escalante assured the man, if he was watching TV, that police wanted the confrontation to end peacefully.
