Witnesses say a mother drove her mini van into the ocean... with her three kids inside. Take a look at this video from Daytona Beach. You can see the car floating in the ocean. Lifeguards say the woman was driving on the sand when without warning she headed straight for the ocean. Her children were trapped inside- They're just five, seven and 10 years old. A tourist rushed in with lifeguards...and saved them. The kids are physically okay...we're told their mother was incoherent when police tried to question her. They are now investigating.
