KERRVILLE, Texas -- Several hundred people gathered for a worship ceremony at a high school stadium in Texas on Wednesday evening to remember the at least 120 people who died in the catastrophic flash floods over the July Fourth holiday, as well the many still missing.

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.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

TEGNA Texas created a new charitable fund raising money to support people impacted by devastating floods in Central Texas.

Kerr County officials say they are still focused mainly on the search for survivors with hundreds still missing and weren't yet examining how the emergency response unfolded.
