Dustin Keelty Death – Obituary, Cause Of Death – Some or you may or may not remember firefighter Dustin Keelty. WCAX did an article on this local firefighter from Milton last year that was battling ALS. We sadly learned tonight that firefighter Dustin Keelty has sadly passed away. Our thoughts and prayers are with Dustins family and his friends and extended family at the Milton Fire Department.
