Warren was dedicated 29 year employee of the Longmeadow, MA Public Works Department serving as a Working Foreman in the Highway Division. He was tragically killed in the line of duty while plowing snow during severe blizzard conditions on March 14, 2017 having been struck by an Amtrak plow train at an uncontrolled grade crossing on a private road plowed by the town. Due to a stuck vehicle on the road "Cowlesie" was in the process of backing over the crossing when hit.

"Cowlesie's 'Get it Done' attitude was infectious. His positive attitude and work ethic brought out the best in everyone he worked with. We'll miss him every day," said Longmeadow DPW Director Mario Mazza in a statement.
