Zakrzewski, an Air Force veteran, was sentenced to die for the 1994 slayings of his 34-year-old wife, Sylvia, and their children Edward, 7, and 5-year-old Anna, at their home in Okaloosa County in the Panhandle. Trial testimony showed he committed the killings after his wife sought a divorce, and he had told others he would kill his family rather than allow that.
