Sergeant Tyler Milless graduated in 2015 from Minnesota State University, Mankato with a bachelor’s degree in law enforcement and an associate’s degree in psychology. He attended the Minnesota State Patrol academy in 2016. After graduating from the academy, he was stationed in Fairmont, Minnesota, for just over a year.

Deputy Graham has two MADD awards: the first for Drugged Driving Enforcement in 2018 and the second for Outstanding Individual Dedication to Impaired Driving Enforcement in 2016 from the Colorado Chapter of MADD.
