“I absolutely know that he was not involved in the shooting,” Backman said. “He’s a really, very curious guy, a poli-sci major. These kinds of social-political kinds of things really interest him. And he was there to observe.”

Backman says his son is an Eagle Scout who is active and interested the outdoors and target shooting. He stresses that his son was raised right.

“He doesn’t have a racist bone in his body. He’s a very kind person, he was, you know, raised in a home and a school that respect everyone,” Backman said.

Backman’s son and three other men are under arrest on probable cause of assault.
