Don Simons (L) and Clint Followel, volunteers from the First Baptist Church in San Marcos, Texas, help clean Toby McLroy's flood damaged home in San Marcos, Texas, May 26, 2015. Torrential rains have killed at least eight people in Texas and Oklahoma, including two in Houston where flooding turned streets into rivers and led to nearly 1,000 calls for help in the fourth-most populous U.S. city, officials said on Tuesday.
