Prosecutors in Chicago say a third man has been convicted in the 2011 fatal shooting of a 13-year-old Chicago boy.
The Cook County state's attorney says 20-year-old Vito Richmond was convicted Thursday of first-degree murder in the death of Darius Brown. Authorities say Brown was playing basketball in a park when he was shot.
Two co-defendants also have been convicted of murder and were sentenced to 50 years in prison.
Authorities say the shooting was part of a gang war. They say the three men drove up to the South Side park on August 3, 2011, intending to shoot at members of a rival faction of a street gang. They say nine shots were fired and one bullet struck Brown in the back.
Richmond is to be sentenced next month.
