Casey's father passed away suddenly four days after receiving the second dose of the Moderna vaccine. He was previously fit, healthy, and in perfect shape. They claimed he passed away from a "heart attack". Casey and her brother Doug did not believe this, and decided to arrange an independent autopsy. They found that the cause of death was a massive pulmonary thrombosis embolism which blocked all blood flow to both of his lungs. Caused by the vaccine. The coroner stated that it was one of the biggest blood clots he had ever seen, and that it killed him instantly.
