Fire destroyed a two story apartment building in South Point, Ohio early Sunday morning, leaving two families homeless.

Firefighters responded to the alarm around 1:45 Sunday morning and tell WSAZ.com the flames were already shooting from the roof and windows of the building when they arrived. Two families living in the building were able to get out unharmed.

The building, one of four similar duplex buildings that make up the complex on Stanley Drive, was heavily damaged by the flames.

Firefighters were able to bring the fire under control in about half an hour. The fire was contained to the one building. Firefighters from the South Point Volunteer Fire Department and three neighboring departments responded.

Firefighters say they don't know what started the fire yet. An investigator from the State Fire Marshal's Office is expected on the scene early Sunday morning.
