Chief Jackson was hired as a firefighter in 1990 and worked his way up through the ranks as an Engineer, Lieutenant, Captain and Training Bureau Chief. He was promoted to Assistant Chief of Operations in 2016 and stepped down in August of 2019 due to health reasons.

Since Jackson’s death, firefighters have stood watch at the Crown Hill Mortuary in a tradition called an Honor Watch. The firefighters will take shifts around the clock until Jackson’s funeral service.
