State and local officials in Texas have come under scrutiny over the lack of sirens in place to warn people of impending flash flooding.

Two grandchildren of a former Detroit Free Press publisher and executive editor were among those killed in catastrophic flooding that overtook a girls' camp in Texas. David Lawrence Jr. confirmed his 8-year-old twin granddaughters, Hanna and Rebecca, died in the flooding over the July 4 weekend at Camp Mystic in Texas.
