An 11-year-old boy was found dead in a vehicle that was swept away by flood waters in Louisiana on Monday, as persistent thunderstorms threaten flash floods across a huge swath of the country throughout the week. Multiple northern Louisiana emergency agencies responded to a call Monday morning about a vehicle that had been carried into a creek by floodwaters, according to a statement from the Ruston Police Department. The driver of the vehicle, a woman who was reported to be a grandmother to the boys, was able to escape but a 7-year-old boy and 11-year-boy old were missing.
