Then she noticed a woman, a complete stranger who wanted to help. They were able to turn the batter on and off to get the window down. They collapsed the car seat and pushed the baby out the window to the stranger.
Several people were calling 911 while the woman ran the boy to safety and then went back down to help the couple out.
"We also had to get out the passenger window because we couldn't open the doors of the car," Coleman said.
The couple got the stranger's first name, but in all the craziness, they didn't get to properly thank her.
"I don't even want to think about where we would be if she hadn't been willing to help people she didn't even know," Abby said.
The car was destroyed.
The Flynn family was headed back to Nashville Monday night with a rental car.
The woman who helped them was Sandra Patterson. She was on her way to the store when the deep water on Rapid Run Road forced her off into a LaRosa's parking lot.
"I have never seen a road flood like that," she said. "It looked like the Ohio River."
When she saw what was happening to the Flynn family, she ran down to help them get the baby out.
"I jumped out on the wall and put him in my car, and then I went back for them," she said.
Patterson said it was simply a case of being at the right place at the right time.
"It's nothing that I would normally do, but just something told me to go down there," she said. "I went out and did what I hope somebody would do for me if it was me and my family."
