Jeff Bradstreet, the controversial autism doctor who authorities say committed suicide on June 19 following a federal raid of his offices ... was closely involved with a European company that provided the drug targeted in the search. On June 19, the day of Bradstreet's death, a European news report described the deaths of five people at a Swiss clinic run by the company, First Immune. The condition that led these people to the clinic remains unclear, as is what caused their deaths, but each patient reportedly paid 5,000 euros per week (about $5,400 US) for treatment. The First Immune Facebook page ... includes a post by a page administrator about the death of Bradstreet that claims: "Dr Bradstreet has been under attack by big pharma for his success during all his professional life so there is no way he would have committed a suicide for just another attack. He was murdered; the FDA were clearly involved, and the other suspect is the MMR vaccine co-orporations, who work with the FDA." Rumors of a murder conspiracy continue to buzz around Bradstreet's death, and family members have used money from a fundraiser to hire private investigators to look into it.
