One of our department’s favorite officers has officially retired and left us to enjoy his next chapter in life! There was one last roll call, one more trip around the city he has watched over for twenty eight years, and one final radio check announcing that Lieutenant Thomas Leassner has ended his five decade long career in law enforcement. Tom came to us after serving with the St. Louis Municipal Police Department for over two decades, and after retiring there he started his next chapter in policing with The City of Arnold. With our department, he would rise through the ranks to become a Watch Commander and guide many a young officer’s career by way of his knowledge, empathy, and commitment to the profession he loved. We never quite believed the day would come when his laugh would not echo throughout our hallways, but it has, and it will most certainly be missed. God speed sir, you’ll always have a home at The Arnold Police Department.
