A boy was killed in a Chicago shooting on the city's South Side Wednesday morning, police said.

Chicago police said an unidentified male juvenile was found outside in the 6000 block of South Prairie Avenue in the city's Washington Park neighborhood just before 8 a.m. He had a gunshot wound to the chest and was pronounced dead at the scene.

The shooting is believed to have happened overnight, but officers didn't get called to the scene until Wednesday morning.

A vehicle in the back yard of an apartment building had multiple bullet holes. A grandmother who lives in the complex next to the scene said she was disturbed to see this investigation so close to where her family lives.

"It's senseless," she said.

Police nor other officials have verified the boy's age.

No one is currently in custody. An investigation by Area One detectives is ongoing.
