Man shot and killed inside Subway restaurant on Chicago's South Side

CHICAGO (CBS) -- A man was shot and killed inside a Subway restaurant in Chatham Thursday night. 

Chicago police said the victim was shot in the head by another man the Subway in the 100 block of West 79th Street around 11:40 p.m. 

The victim was pronounced dead on the scene, while the shooter escaped.

The victim and the suspect did not work at the Subway. It was not clear whether the victim and the shooter knew each other, and the motive was unknown.

The manager of the restaurant said he believed the victim walked over from the gas station next door.

A woman who brings her grandson here every morning said she is in shock. 

"I'm blown back," She said. "I mean, it is 79th Street, so you get what you get late at night. But I'm shocked though."

While the Subway restaurant opened Friday morning, police later hung up a sign stating the restaurant is closed. The orange sign says the business presents a public safety threat because of a violent offense during operating hours.

The restaurant will have to go through a nuisance abatement hearing, and it will be up to Mayor Brandon Johnson to determine when the restaurant can reopen.

No arrests have been made. Police are searching for the shooter.
