After deadly floodwaters swept through Central Texas, there are questions about the timeline of weather alerts and possible gaps in the warning system.

Kerr County, Texas, lacked a “last mile” warning mechanism that could have saved residents before the deadly floods devastated the area, including a children’s summer camp, killing more than 80 people.

Emergency responders continue to search for missing people and local police said efforts have been slowed by "sightseers who are making things worse."
