VIDEO: No injuries were reported after a fire broke out at duplex in Overland Park. It happened just after 1 a.m. Wednesday in the 8600 block of Riggs Street. First units on the scene reported heavy fire from the back of a two-story duplex. Firefighters went to work attacking fire on the exterior of the back side of the structure, while additional crews entered the duplex to conduct a search. All occupants were determined to be out safely. In a matter of minutes, firefighters knocked down the exterior fire, which involved the first and second story and a lower level walkout in the rear of the structure. Crews then worked for about another half-hour overhauling hot spots and making sure the fire had not extended into the living space. The seven occupants of the unaffected unit will be able to reoccupy.
