Dr. Daniela Schreier discusses Lt. Gliniewicz death investigation

CHICAGO (FOX 32 News) - An official briefed on the two-month investigation into the shooting death of an Illinois police officer has told The Associated Press that authorities are going to announce that he killed himself.

The death of Fox Lake Police Lt. Charles Joseph Gliniewicz in September triggered a massive manhunt and an outpouring of grief in the quiet town and surrounding communities.

Shortly before his death, Gliniewicz radioed dispatchers that he was pursuing three suspicious men, but speculation about a possible suicide mounted as investigators struggled to find solid leads.

The official who spoke to the AP about the impending announcement insisted on anonymity because he isn't authorized to brief the media.

The Lake County Sheriff's Office said only that the Wednesday morning news conference will reveal "conclusive results" of the investigation. A sheriff's office spokesman refused to provide details ahead of the announcement.
