I have often wondered about the CDC Officer who went missing in 2018, and was later found dead in the Chattahoochee River in Georgia. He supposedly had raised warning about the Flu Vaccine and its dangers. His name was Timothy Cunningham and he was 35 years old. He was an epidemiologist and was the head of a CDC division dealing with population control.. He went missing on February 12, 2018, and after a massive search, his remains were found in the Chattahoochee River. Apparently, he shared his opinion that the year's flu shot was behind the deadly outbreak of the flu that winter. He warned co-workers that he was likely to be fired for stating his opinion. When he went missing, his cell phone, keys and wallet were found on his dining room table. HIs dog was also found and was being cared for by a neighbor. Snopes "debunked" any foul play, because they could find no evidence. Still many believed he was murdered as he was successful and had no reason reason to kill himself. Very Strange that he ends up in the river.
