A Mississippi man drowned attempting to cross a rain-swollen creek in a car with two other people, The Associated Press reported.
John Howard Anderson, Jr., 57, was trying to drive a van with two other passengers across the creek when Jonathan Weeks and his wife saw them.
"It all happened so fast," Weeks recalled. "They were in there trying to get out and panicking. The power was out so everything was dark."
"We threw them a rope and tied it to a tree," he continued. "We got two of them to the bank and were trying to help the driver. We had him on the rope and were trying to pull him in, but I don't think he was able to hold on."
