From Chicago FD Media on Twitter:
The Chicago Fire Department gathered to remember the sacrifice made by Firefighters Corey Ankum & Edward Stringer 10 years ago fighting a fire on 75th Street at an abandoned former dry cleaner.
The bell was rung to not only honor Firefighters Corey Ankum & Edward Stringer, but to also honor and remember the 21 CFD members lost during the Chicago Stockyard fire in 1910.
