Ten from firefighter's family killed in house fire

Fire tore quickly through a house in the wee hours of Friday, in Pennsylvania killing seven adults and three children and horrifying a volunteer firefighter who arrived to battle the blaze only to discover that the victims were his family, authorities said.

Ten victims included his son, daughter, father-in-law, brother-in-law, sister-in-law, three grandchildren and two other relatives. Baker, who was relieved of his firefighting duties because of his relationship to the victims, said 14 people were living in the home.

One of them was out delivering newspapers, and three others escaped, he said. Baker said that the address initially given for the call was a neighboring home, but that he realized it was his family's residence as the fire truck approached.

Harold Baker, relative of victims said "Couldn't get in there to save them. That's my biggest thing that's been on me. I couldn't get in there to save them."

A criminal investigation into the fire is underway, authorities said.
