Report: Illinois police lieutenant's death was suicide

Report: Illinois officer killed himself in staged murder 02:39

FOX LAKE, Ill.-- Sources told CBS Chicago Tuesday that investigators have determined the death of Fox Lake Lieutenant Joe Gliniewicz was a suicide.

Lake County police officials will be holding a news conference Wednesday morning where they will announce "significant new information" about the case. Officially, they would only tell WBBM that the investigation has concluded.

Gliniewicz was found shot to death Sept. 1 after he radioed that he was pursuing three suspicious men in a remote area of the village near the Illinois-Wisconsin state line.

Police had said Gliniewicz provided only a very vague description of the three suspects -- two white males and one black male, WBBM reported. Despite a massive manhunt, police hadn't made any arrests or identified any suspects.

Questions had swirled around the investigation -- particularly since the county coroner said he had been unable to rule the 52-year-old Gliniewicz's death a homicide, suicide or an accident.

Lake County Major Crimes Task Force Commander George Filenko previously emphasized the investigation was "strictly" being conducted as a homicide probe, though he acknowledged detectives weren't ruling anything out, including the possibility of suicide.

Gliniewicz was married and the father of four sons. A career police officer, he worked for the department for over 30 years and was known in the community as "G.I. Joe." He was set to retire a month before he died but agreed to stay on the job.
