Fox Lake Cop's Personnel Files Indicate Litany of Complaints

— -- Recently released personnel files are painting an even more startling picture of the disgraced Illinois police officer who killed himself after what authorities have described as years of "extensive criminal acts."

Fox Lake Lt. Charles Joseph Gliniewicz -- who died by a "carefully staged suicide" in September -- allegedly committed years of crimes, including stealing and laundering money from the Fox Lake Police Explorer Post youth program.

The personnel files show in 2009, an anonymous group of Fox Lake police officers submitted a letter to the mayor of the twon with a long list of complaints about Gliniewicz.

Among the allegations were an inappropriate sexual relationship with a subordinate officer, being "highly intoxicated" in public and also Gliniewicz allowing members of the police youth program he directed to dress "as police" and use squad cars.

"He had a side he would present to individuals and a side that nobody knew about, that he was keeping a secret, that he was trying to hide," Lake County Major Crime Task Force spokesman Christopher Covelli said today.

After Gliniewicz's death in September, the community honored him as a fallen hero and comforted his family. A massive manhunt was undertaken.

This week, however, authorities revealed that he had used thousands of dollars for personal purchases. Authorities also said that he'd allegedly discussed putting a "hit" out on Fox Lake village administrator Anne Marrin because she had ordered an audit of his youth program.

Gliniewicz was found shot dead in the Chicago suburb of Fox Lake, Illinois, Sept. 1, shortly after he radioed that he was chasing three suspects. Authorities said fearing the embezzlement would be uncovered, Gliniewicz had developed an elaborate plan to make his suicide look like murder.

Gliniewicz's "ongoing criminal activity" was revealed by analysis of his text messages and financial records, officials said. Gliniewicz was 52 and nearing retirement after more than 30 years with the police department.

A statement Wednesday from the attorneys for the Gliniewicz family said: "Today has been another day of deep sorrow for the Gliniewicz family. The family has cooperated with the Task Force's investigation and will not comment at this time. The Gliniewicz family requests that their privacy be respected as they continue to cope with the loss of the beloved husband and father."
