Milan K-9 gets trained to investigate fires May 11, 2021 MILAN, Tenn. — Tuesday was Test Day for fire investigator Brent Autry and his K-9 Tony, who is trained in detecting accelerants at fires. “As you see today, we’re going to do basics,” Autry said. “It’s the first thing we do in the morning, and last thing we do in the evening.” They would typically travel to do their recertification, but since it was through video this year, we got to join in. “We have to go through this process and have the owner of the company and everyone watch us and make sure we’re doing everything right,” Autry said.
