A man is dead after he was shot and killed by a family member during an altercation inside an Oak Park residence on Sunday afternoon.

A spokesperson for the village said around 1:47 p.m., Oak Park police officers responded to the shooting in the 400 block of South Ridgeland Avenue.

A caller reported that the victim, who the village identified as 26-year-old Anthony Brooks, was in an altercation with his 23-year-old brother. The two lived together, according to the village.

The caller also reported that they told the suspect to take the bullets out of the gun, leave the gun in the home, and go outside.

Responding officers found the victim with an apparent gunshot wound to the head. Paramedics pronounced him dead at the scene.

An employee at a nearby business, who did not want to be on camera, said he didn't hear any shots but heard the responding sirens and watched as an officer pulled a long gun from the vehicle.

Concerned there could be an ongoing safety issue, the employee said he waited to see if police had any warnings, but they kept their work contained to the area around the homes. The yellow crime scene tape was up for more than six hours.

The suspect was arrested without incident and taken to the police station.

The investigation into the incident remains ongoing.
