VIDEO: The cause of an early morning house fire on Gray Avenue in Liverpool is still under investigation. Firefighters were called just before 6:30 Sunday morning, after a passerby saw and reported the flames. As Liverpool and four other departments arrived, flames billowed from the house. Liverpool Chief Jerry Payne tells us the home's only resident was found in the back of the house. He was taken to Upstate, for treatment of smoke inhalation. The house was significantly damaged by the flames.
