ROUND LAKE BEACH, Ill. (AP) — Authorities say an Illinois police officer who staged his own death to look like others killed him in the line of duty felt that auditors were close to discovering that he’d been embezzling money from a youth program he oversaw.

Lake County Major Crimes Task Force Commander George Filenko says the Village of Fox Lake was conducting an internal audit that police Lt. Charles Gliniewicz (GLIHN’-uh-wihts) believed would lead to him.

Gliniewicz was found dead with gunshot wounds on Sept. 1 after telling dispatchers he was pursuing three suspicious men. A massive manhunt and two-month investigation followed. Authorities announced Wednesday that they concluded he killed himself.

Filenko said the investigation into the embezzlement “strongly indicates” at least two other people were involved, but he refused to provide details.
