CHICAGO (CBS) — A 40-year-old Evanston man died early Wednesday, hours after he was shot about four blocks from his home.

Keith Tucker, 40, of 1832 Laurel Ave. in Evanston was shot just after 1 a.m. on the 2000 block of Church Street, according to a release from Evanston police.

Officers found the victim on the ground with a single gunshot wound to the head. Paramedics took him to Evanston Hospital, where he was pronounced dead at 3:39 a.m., according to the Cook County Medical Examiner’s office.

The area where he was shot is in the western part of Evanston, a few blocks from the North Shore Channel. Parts of the area have struggled with a reputation for gang activity.

A preliminary police investigation — conducted by Evanston police and the North Regional Major Crimes Task Force — found that Tucker had been in the company of one to two others at the intersection of Grey Avenue and Church Street.

At about 1:04 a.m., one of the other people produced a gun, “which resulted in (Tucker) receiving a single fatal gunshot wound to the head.”

Investigators continued Wednesday to process the crime scene and conduct interviews to determine the shooter’s identity and motivation.

The motive for the shooting was not immediately known.
