The search for victims of deadly flooding in Texas Hill Country is headed into its third week as officials try to pin down exactly how many people remain missing and lawmakers prepare to discuss authorities' initial response and providing better warning systems.
Flash floods killed at least 135 people in Texas over the Fourth of July holiday weekend, with most deaths along the Guadalupe River in Kerr County, about 60 miles (100 kilometers) northwest of San Antonio. The Hill Country is naturally prone to flash flooding because its dry, dirt-packed soil cannot soak up heavy rain.
