In June 2017, a 4-year-old boy in Texas died under tragic and seemingly inexplicable circumstances. The boy, named Frankie Delgado, was playing in knee-deep water when a wave knocked him over, causing his head to dip below the water. Despite being monitored at the time, Delgado inhaled a small amount of water. After a brief coughing fit, he was able to calm down. The next night, he began to vomit and experience diarrhea. Later that week, he died suddenly.
