CHICAGO (CBS) — A 30-year-old man was shot to death early Friday in the Lawndale neighborhood on the West Side.

Officers responding to a call of a person down at 1:07 a.m. found 30-year-old Lavaris Johnson with multiple gunshot wounds in the 1600 block of South Millard, according to Chicago Police and the Cook County medical examiner’s office. The circumstances of the attack were unknown.

Johnson, who lived in the 4100 block of South Berkeley, was pronounced dead at the scene at 1:28 a.m., authorities said.

Three hours earlier, a man of the same age was shot in the arm in a drive-by about a mile away in the same neighborhood. Police said investigators were looking into the possibility that the two shootings were related, but could not confirm a connection Friday morning.
