Seven people, among them a child, were wounded following a mass shooting at a house party Saturday night in Harvey, Illinois.

A spokesperson for the City of Harvey said shortly after 8 p.m., officers responded to the 14400 block of Des Plaines Street in the south Chicago suburb for a shooting at a house party.

Two shooters arrived at the scene and opened fire on the gathering, the city said.

As of late Sunday afternoon, shattered glass and evidence markers remained at the scene.

Preliminary reports indicated that seven people were shot — including a 4-year-old boy who suffered non-life-threatening injuries, and his condition was stabilized.

Four additional people were shot and taken to area hospitals in unknown conditions. Their conditions were also stabilized.

"This is something you would hear if you were at war," said Willie Hill, 73, who was sitting on his porch when he heard several gunshots. "It was terrible. Loud. I mean, you could tell it was nothing to play with."

A concealed carry license holder who was at the party returned fire — striking and killing one of the suspects at the scene. The Cook County Medical Examiner's office identified him as 24-year-old Charles Lipsey.

"It's good that someone had a weapon to return fire, but the first question is, why would fire be directed to that location?" said Hill.

The second suspect was injured and taken to the hospital, and later placed in police custody.

Michael Parker lives across the street from the shooting and says this was too close to home for him.

"Bullets fly," Parker said. "They don't have a name on the bullet."

The City of Harvey said the shooting was an isolated incident, with no ongoing threat to the public.

Man found dead in possible retaliatory shooting

The spokesperson said just before 5 a.m. Sunday, officers responded to reports of gunfire near the 200 block of Calumet Boulevard.

A man was found inside a minivan who had suffered multiple gunshot wounds. Despite emergency response efforts, the victim was pronounced dead at the scene. Examiners identified him as 28-year-old Jeremiah R. Adutu-Bofah.

Preliminary information indicated the shooting may have been in retaliation for the mass shooting. 

Investigators are actively following leads, and witnesses are cooperating with police, the spokesperson said.

Investigation into the shootings remains ongoing. No further information was available.
