On July 4, 2025, a one-in-a-thousand-year flash flood devastated Camp Mystic in Texas's Hill Country, killing 27 young campers and counselors. NBC's Lester Holt and Morgan Chesky discuss the tragedy, what warnings were missed, how a community remains divided over the camp's future, and why eight grieving mothers continue demanding accountability. A proposed flood warning system that could have saved lives was designed years earlier but rejected for state grant funding, leaving the community reliant on outdated phone-tree alerts.
