JEANNETTE, Pa. — Four children and an adult were killed in a fire Wednesday morning in a home on Guy Street in Jeannette, just off Harrison Avenue. Fire officials tell our news partners at WPXI, an adult and two children were rescued before flames spread out of control. Video from the scene shows intense flames that spread to a neighbor’s home. Both houses are a total loss, officials said. Flames also spread to a vehicle when the house collapsed. “We had an issue with the water supply,” Jeannette Fire Chief Billy Frye said. “The first hydrant that we hit gave us a little bit of water but not even enough to make it up the hill to the scene, so we did run off of tank water at one point. At that point, the fire was well involved and we had to pull our guys out.” The cause of the fire is under investigation.
