Saturday (2/13) is the 45th anniversary of the fire and explosion at 6117 N Elston Ave in Chicago which resulted in the line of duty deaths of CFD Lieutenant William Quinn and Firefighter Martin Dyer. Both men were inside of the A. A. Englehardt Heating and Appliance Dealership when an explosion sent the roof crashing down on them. I just happened to recently acquire these color photos of the search for these men as well as the removal of FF Dyer in the final image. The battalion chief seen looking toward the camera in the one image is Battalion 22. Also Commissioner Quinn can be seen in the background of the one image. The photographer was George Mars Cassidy. Thought I would share these as I do believe they may not have been seen by the public before now.
