CHICAGO (CBS) — Michael Brown Jr. was sitting with a friend in an SUV in his driveway Thursday night, when another man shot them both, killing Brown and wounding his friend.

“Mike had a heart of gold. He would give you his last. That’s his legacy,” Brown’s father said.

Sauk Village police said, around 9:15 p.m., officers responded to a call of shots fired near 219th and Clyde. When they arrived, they found two 33-year-old men who had been shot inside an SUV.

One man was pronounced dead at the scene, the other was airlifted to Advocate Christ Medical Center in Oak Lawn.

The dead victim’s father identified him as Michael Brown Jr.

Brown’s father said his son and his son’s friend were sitting in an SUV parked in the Brown family’s driveway, when another man came up to them and started talking to them.

At some point, the man shot both victims.

Brown Sr. said he never heard the gunshots, only screams from his other children that his eldest son had been shot.

“You could see him, he’s slumped over to his right,” Brown Sr. said.

Brown Sr. said he begged his son to stay alive.

“I’m here. Your dad’s here. Your mom’s here. Your sister’s here. Breathe, just keep breathing, the ambulance is on the way,” he said.

Sauk Village police said Brown Jr. died at the hospital.

“This is something I don’t want. This stuff has to stop,” his father said.

Brown Sr. said the family might know the shooter, and that he lives a few blocks away.

“This gentleman that shot my son was disturbed. He was disturbed from what I understand,” he said.

The family’s focus now is learning why Brown Jr. was killed.

Police said detectives were interviewing several witnesses.

Authorities have not said if anyone is in custody.
