As Twitchy reported earlier, a massive manhunt is underway to capture the suspects in the shooting of a police officer in the Chicago suburb of Fox Lake following a traffic stop earlier today.

The Chicago Tribune has identified the police officer as Charles J. Gliniewicz. ABC7 reports that Lt. Gliniewicz went by Joe, and was nicknamed “G.I. Joe.”

The Northwest Herald reports:

Gliniewicz leaves behind a wife and four boys who range in age from their early 20s to teenager, Giorgi said.

He also was a leader for the Fox Lake Police Explorer Post, which trains high school students who are interested in law enforcement.

He served in the Army, both active-duty and reserve, from 1980 until 2007, and left as a first sergeant, according to sources. Gliniewicz graduated Antioch Community High School in 1981, and held a master’s degree in criminal justice from Kaplan University.

The search continues for the suspects in the shooting.
