My oldest daughter works as a 9-11 operator here in Palm Beach County. She took a call a few nights from a woman, who was driving with 2 children, her car had flipped over while driving and landed in a water canal upside down. The woman had the presence of mind to call for help on her cell phone. One could hear the water rushing into the car as she talked. It was night time, very dark, no street lights. The police frantically tried to find the car and to get help to the scene.
There were no survivors.
