From the article:
Police say Pelle became agitated and started swearing at the girl and her family and that's when the girl's father stepped in..
"The gentleman feared for safety of his children because the gentleman was big guy, over 6 feet tall, 300 pounds and he had 3 kids in the car, so he ended up taking a baseball bat out of his car to protect his children," said Sgt. Lisa Cotta.
That's when police say Pelle pulled out his gun. He took off, but not before witnesses took down his license plate and called police.
"I just couldn't believe it happened over nicking a car and I understand things are very expensive to fix and that might have been the last straw for this gentleman, but you really have to put things in perspective," Sgt. Cotta said. "Maybe count to ten, take a deep breath, really put things in scope. So yea, it was really quite bad."
