MELROSE PARK, Ill. (CBS) — A man was killed during a bizarre home invasion in west suburban Melrose Park on Sunday.

Police said two robbers cut power to a home in the 1400 block of North 24th Avenue in Melrose Park at about 4 p.m. Sunday, then entered the home and held a woman and her two children at gunpoint.

The suspects then shot and killed Cleon Wilson, 29, when he walked in on them.

CBS 2’s Susanna Song reports police believe the man walked in on a robbery in progress, and they don’t believe the attack was random.

Police said the suspects held the woman and her children at gunpoint in a bedroom, and demanded money.

When Wilson returned home during the robbery and walked into the bedroom, he was shot and killed.

Police said Wilson and the woman were either married or dating.

The building’s landlord said the woman had been renting a unit there for the past few years.

“On the lease, it’s three persons; her and two children. One boy, one girl,” Felix de la Rosa said. “I know she’s got a boyfriend, but I see him all the time here. He looked like a normal guy, you know.”

After the shooting, the suspects fled the scene on foot and went a block south into a waiting vehicle. Police are still trying to determine if anything was taken from the home.

Residents were stunned on Monday morning.

“This is crazy, we didn’t hear anything. I had guests over, and everything, but we didn’t hear anything yesterday, and I was home all day.” said a neighbor, Linda Sloan. “The place was surrounded by police officers, bringing someone out on stretcher, and girl and daughter got in back of police car.”

No arrests had been made as of Monday morning.
