Drivers who saw the crash followed Cooper and blocked him in his SUV at a stoplight. He couldn’t get out. They called police and gave police directions to where they were. 

“There were a couple of vehicles who followed him. They got to an intersection where they were able to pin him in.. the best thing about that is he couldn’t hurt anyone else,” said Tammy Sisson.

McKenna was on her way home Wednesday night around 5:30 p.m. when another vehicle pulled out in front of her.

She swerved to miss the driver, who T-boned her SUV, and took off.

Another family invited the teen to sit in their car, until officers arrived.

“I honestly don’t know what I woud’ve done without that family, because I was alone,” says McKenna. “I had no one else in the car. I was by myself. 16 years old. I’ve been driving for 2 months. I was scared out of my mind.”

Tammy says she’s been in contact with some of the drivers who kept her daughter safe.
