Omaha Fire investigators look for the causes of two fires within eight hours of each other in a vacant house near Florence Blvd. and Clark Street.
The first fire was reported early Monday afternoon and was brought under control in about ten minutes.
Then firefighters were called back to that location for another fire Monday evening.
They say that fire was more difficult to extinguish due to its location in the house.
No injuries reported in either fire;
Anyone with information can call the ARSON hotline at 402-444-FIRE or "Omaha Crimestoppers" at 402-444-STOP
