The high school senior had visited the water park on a church trip. At one point, she was riding on a raft that overturned, health officials said last week. Health officials said samples of her cerebral spinal fluid tested positive for the amoeba, confirming the cause of death. The U.S. National Whitewater Center in Charlotte was mostly closed Friday after water samples tested positive for Naegleria fowleri, an amoeba that can cause a rare and deadly brain infection. Friends and family gathered to say goodbye to Seitz at a funeral on Saturday, according to CNN affiliate WCMH.
