Jake Knutson was working across the street from the tow yard and watched what he described as a massive police presence outside the business.

“It was intense,” Knutson said. “I figured it was, somebody got killed, somebody was running from the police.”

Live ammunition in police training exercises is typically only used at shooting ranges.

“I definitely didn’t think it was an officer shooting another officer, on accident of course,” Knutson said.
