Lake County Sheriff's Office spokesman Sgt. Christopher Covelli says the officer radioed in Tuesday morning to tell dispatchers he was chasing three men on foot, but communication with him was lost shortly after. Covelli says the officer's backup arrived to found him injured with a gunshot wound and that the officer died at the scene. He was killed in Fox Lake, 55 miles north of Chicago.
The officer was later identified as Charles J. Gliniewicz, a 32-year veteran of the Fox Lake Police Department.

Undersheriff Raymond Rose tells the Chicago Tribune that Gliniewicz was stripped of his gun and other equipment.
At a press conference this morning, Rose said a perimeter has been set up and the suspects were all male, one black and two white. He added, “If (residents) see anybody in their area … that doesn’t belong or doesn’t look right, they should call 911."
