Mourning begins in Texas where more than 170 are still missing from flash floods

The victims include three friends who had gathered for the July Fourth weekend, 8-year-old sisters who were at summer camp and a 91-year-old grandmother known for her sharp wit.

More than 170 people have been reported missing, most in Kerr County, where nearly 100 victims have been recovered. The death toll remained at 120 Thursday.

Authorities say they have carefully gone over the list of those unaccounted for but those numbers are often tough to pin down in the immediate aftermath of a disaster.

More than 2,000 local, state and federal workers were involved in the search for victims. Stifling heat and mounds of trees, hunks of lumber and trash made the task more difficult.

At a small shopping center damaged in the floods, people piled debris gathered from the rivers. Officials hope to eventually set aside personal items so residents find their possessions.

On Wednesday, hundreds prayed, wept and held one another at a prayer service, among the first of many somber gatherings to come in the weeks ahead.

"Our communities were struck with tragedy literally in the darkness," said Wyatt Wentrcek, a youth minister.

David Garza drove more than an hour to support loved ones affected by the floods.

"I'm from here, and I was here in the '78 flood and the '87 flood," Garza said. "I just wanted to be a part of this."

Some at the service wore green ribbons for the girls from Camp Mystic, the century-old Christian summer camp where at least 27 campers and counselors died.

Parents of children who were at the many summer camps in Hill Country have credited the teenage counselors with ushering campers to safety and helping keep them calm during the chaos.

Texas Gov. Greg Abbott called on state lawmakers to approve funding for new warning systems and emergency communications in flood prone areas when the Legislature meets later this month. Abbott also asked for financial relief for the response and recovery efforts.

"We must ensure better preparation for such events in the future," he said in a statement Wednesday.

Public officials in the area have come under repeated criticism amid questions about the timeline of what happened and why widespread warnings were not sounded and more preparations were not made.

Kerr County Sheriff Larry Leitha has said those questions will be answered after the victims are recovered.

Local leaders have talked for years about the need for a flood warning system, but concerns about costs and noise led to missed opportunities to put up sirens.

President Donald Trump has pledged to provide whatever relief Texas needs to recover and is planning to visit the state Friday.

Polls taken before the floods show Americans largely believe the federal government should play a major role in preparing for and responding to natural disasters, which are becoming a growing worry. On Tuesday, a deluge in New Mexico triggered flash floods that killed three people.

The devastation in Texas stretched from Hill Country all the way to just outside the state's capital. At least 15 people died in the Austin area and adjacent counties.

Just north of Austin, floodwaters from the San Gabriel River swamped two RV parks in Georgetown.

Teri Hoffman watched the water lift up her camper with her two dogs inside.

"The camper just kind of goes over on its side and starts floating. And then all the other campers just started crashing into it," she said.

Rescuers were able to save the dogs and she managed to dig out the last picture she has of her late mother. Everything else from the RV where she lived with her husband and children is gone, she said.

"I couldn't look at it," Hoffman said. "I had to walk away."
