Dr Bradstreet's body was found by an angler on June 19, and local police are treating his death as suicide and are describing the gunshot wounds as 'self-inflicted'. But his family does not believe he did take his own life, and are raising funds online to investigate his death, and want to have "an exhaustive investigation into the possibility of foul play".
Dr Bradstreet, who was 60, believed that mercury in MMR and other vaccines were responsible for autism-a theory that has also been associated with Dr Andrew Wakefield-and had published several papers about the topic.
He treated autistic children with supplements designed to lower mercury levels in the body.
His offices in Georgia had been raided a week before his death by FDA agents, although the administration has refused to reveal the reason for its investigation.
