Drowning California Today in California: Andrea Diaz Mondragon, 17, of Santa Maria, California, died after slipping into a river near Sequoia National Park on June 19, 2026, while visiting the area for the first time with her older brother and friends. The group had planned a short hike and noticed a trail leading down to the river near the park entrance when Andrea fell into the cold, swift water. First responders pulled her from the river and transported her to a hospital, where she died. Her death marked the ninth drowning in Tulare County that year, occurring days after park officials had warned visitors to stay back from riverbanks that can become hazardous during warm-weather runoff.
