An eight-year-old girl from Ruston, Louisiana, has succumbed to a rare and usually fatal brain-eating amoeba, Naegleria fowleri. Lillian Smart passed away on Saturday, August 23, 2026, just one day after her birthday. Her family announced her passing on a public Facebook page, stating that the injuries to her brain were too severe for her body to overcome.
