The Case of “Reckless” Ronnie Fender-bender

• Ronnie Fender-bender loves cars, but he has already been in several minor accidents. Recently, Ronnie brought in his 1966 Ford Thunderbird to the auto body repair shop with a massive dent in the front bumper. He told Tony, the repair technician, his insurance would cover the repair because it wasn’t his fault. He claims a deer ran in front of his car. The insurance company doesn’t believe the damage could have been done by a deer. They send Clint, a claims assessor, who collects samples from Ronnie’s bumper and labels them “unknown”. What type of cells are on the unknown slides?

The accident was so damagingit changed the kind of car!
