An early morning fire is a reminder to close your bedroom door at night. The La Crosse Fire Department responded to a house fire just after midnight this morning. A female was reported to be trapped inside her bedroom with her dog according to firefighters. The fire crew was able to extinguish the first floor fire, while the woman was held safely in her bedroom. Then were then evacuated, as well as the two tenants of the upstairs unit. Firefighters note that because the bedroom door was closed when the fire started, it limited where it spread to. The cause of the fire is under investigation.
