From the Waukegan Fire Department Facebook page:

Waukegan fire crews along with help from many other neighboring departments are working to extinguish a stubborn fire this cold Christmas morning. Please avoid the area of S Genesee and Washington Streets if you are out this morning.

Our crews have safely finished extinguishing the fire at 18 S Genesee. The structure was currently being demolished as part of a city effort to eliminate problematic vacant structures. With the help of over ten other fire departments and approximately 50 firefighters as well as assistance from Webb excavating, the fire was extinguished by 10am this morning. Working in extremely cold and icy conditions there were no injuries reported. Also a big thank you to Mayor Cunningham for coming out and thanking all for their efforts on this bitter Christmas morning.
