The son of a suburban Chicago police officer who was shot to death this month is angrily disputing any suggestion that his father took his own life.

Donald "D.J." Gliniewicz tells the (Arlington Heights) Daily Herald (http://bit.ly/1UVryFP ) that Fox Lake Police Lieutenant Charles Joseph Gliniewicz "never once had a single suicidal thought in his life" and that his family is upset about any suggestion that he killed himself.

The comments follow Lake County Coroner Dr. Thomas Rudd's statements last week that he had not yet ruled out the possibility that Gliniewicz's Sept. 1 death was a suicide or an accident.

Gliniewicz was shot in a remote area after saying on his radio that he was pursuing three suspicious men. No arrests have been made and no suspects have been identified.
