The names of three Missouri firefighters who died in the line of duty last year will be added to the National Fallen Firefighters Memorial this weekend. Firefighters William Vorwark of Odessa, Dale Haddix of Schell City, and David Grass Junior of Ste. Genevieve are among 80 firefighters to be remembered at the Memorial in Emmitsburg, Maryland. That’s the home of the National Fire Academy.
