James Jeffery Bradstreet, a 61-year-old white man, was found dead June 19, 2015, in Chimney Rock, North Carolina. A fisherman discovered his body in the Rocky Broad River with a gunshot wound to the chest; a handgun was reported nearby. The Rutherford County Sheriff’s Office said the death appeared to be a suicide, but Bradstreet’s family and supporters have publicly questioned that finding and suggested foul play could be involved.

Bradstreet was a controversial figure because of his alternative autism therapies and claims linking vaccines to the condition. Days before his death the U.S. Food and Drug Administration raided his clinic in Buford, Georgia, a development his supporters cite as relevant. His family has raised funds for a private investigation and says Bradstreet’s faith and personal circumstances make suicide unlikely; others propose he might have been killed while at the river, several hours from his home in Braselton, Georgia.

The official determination and the competing doubts leave the case disputed. If anyone knew Bradstreet, his movements in mid-June 2015, or saw anything at Chimney Rock or the Rocky Broad River, please share information.
