FOX LAKE, Ill. -- There's new information in the killing of Illinois Police Detective Joe Gliniewicz.

He was found dead three weeks ago shortly after telling a dispatcher he was pursuing three suspicious men on foot.

His killing sparked a major manhunt in a resort community north of Chicago.

Officials said Monday they've received results on two key tests: gun residue and ballistics.

A task force spokesman said DNA evidence found at the scene, which does not belong to Gliniewicz, is being run through the DNA crime database.

He also said gunshot residue and ballistic tests do not support or exclude any specific theory in the investigation.

Last week, officials said for the first time they were considering homicide, suicide, and any other possible scenarios.

Gliniewicz's son, DJ, spoke with CNN's Anderson Cooper Monday night, saying the suicide theory holds no water.

“I know my father, my family knows my father and his closest friends know him well, he's not someone who ever contemplated suicide, he never had suicidal tendencies or anything like that, that's just a rumor, and that's that, it is a rumor, it is something someone made up because they wanted to interpret the story on their own, I full-heartedly disagree with that statement, although I can't change that person, that individual's mind of creating that saying,” DJ said.

His son also wanted to remind everyone that beyond the headlines is a family in mourning.
