Flames swallowed up an Evansville building this morning. Fire crews were called out at around three oclock to Fulton Avenue and Fountain. Thats the site of the abandoned Kirbys Thrift Shop. When they arrived, the old shop was fully engulfed. Firefighters werent the only ones working to put out the fire safely. Vectren crews came to shut off power. Most of the damage was contained to the back of the building. What they dont know is what sparked it.
