 A Green Country fire marshal is investigating the cause of a house fire. The Sand Springs Fire Department responded to a blaze in an abandoned house near 81st West Avenue and Charles Page Boulevard last Saturday around 4 a.m. Officials say the cause of the fire is still being investigated by the fire marshal, but they think whatever started the fire seemed a little suspicious. Three trucks reportedly responded to the fire. No injuries have been reported at this time. Denver Fox, 1023 KRMG, Tulsa's News and Talk.
