Another red lightbulb has been added to the Keep the Wreath Green campaign after La Crosse firefighters found a fire inside a house's wall. The campaign serves as a reminder of how many fires happen during a year, especially during the holiday season. La Crosse firefighters were dispatched to the home at 1724 Liberty St. for the smell of smoke. Those inside the home could not see where the smoke was coming from. Engine 4 entered the home and called additional units to the scene. Five additional firetrucks and 11 additional firefighters responded to the home. Authorities helped the residents and pets evacuate to a safe, warm place while firefighters continued the search for the fire source. Firefighters used thermal imaging cameras to search for signs of heat.
