NASHVILLE — Three years after Alex Heitman’s reported suicide in Cocke County, his parents still can’t separate facts about the case from all the rumors and innuendos swirling around Oak Ridge, where he lived.

But the audit’s findings weren’t conclusive enough to explain why Alex Heitman, who had once uncovered other massive theft from the school district a few months prior, would want to kill himself, the Heitmans said.

“We don’t know who to believe down there,” said Don Heitman, who lives in Wisconsin with his wife.
