ATHENS, Ga. - Athens authorities say they will have answers this week in the case of former University of Georgia marketing professor George Zinkhan III.

The body of Mr. Zinkhan, who was sought in the April 25 killing of his wife and three other people outside the Athens Community Theater, was found Saturday. Police said he committed suicide in the northwest Clarke County woods after digging a shallow grave for himself and covering up with brush.

Police aren't releasing details until they get the results of an autopsy being conducted at the Georgia Bureau of Investigation's Crime Lab near Atlanta.

Investigators announced that a "concluding" news conference will be held Tuesday, at a time and place to be set today.

Investigators haven't said whether Mr. Zinkhan, 57, left behind a suicide note or other messages, but they said they would have more information after the autopsy.
