Pennsylvania fire kills 10

Fire Chief Chris Benson said he thought space heaters were being used inside the two-story frame house, and that the property's gas service was shut off, but that investigators could not yet pinpoint a cause.

"I think we have a good idea," said Benson, who declined to offer further details Friday because he had to talk with state police.

The fire appears to have started in the first-floor living room. Trooper Bruce Morris said Friday that is where investigators were focusing their efforts.

Classes and other normal activities went on as scheduled at the area schools. Students were excused for the day if needed, and grief counselors were on standby.

Police say the victims are a 40-year-old woman and nine people younger than 20.

Two other people escaped. 1 of them is a woman who jumped from the second floor.

Eight people were killed and two were missing and presumed dead, state police said. Two others escaped.

The blaze badly damaged the light blue house, making it difficult to find and remove the two people who were missing, said Trooper Bruce Morris. The eight victims who were found ranged in age from four months to 40 years.

The house's facade was gone, leaving a view of the inside of the home, remnants of a front porch and a lopsided stove. Two children's bicycles sat in the rubble.

Crying as she spoke, family friend Carol Paruso said three generations lived there.

"They were a tight family and they all took care of each other. That's who they were and that's what makes it so sad," she said.

Bill Fustini, a mail carrier who lives nearby, said his dog woke him up at about 2:30 a.m. When he saw the smoke, he called his son, a firefighter, who told him the home had gone up in flames.

"There was a little girl living in that house and she met me every day and she was the sweetest thing," Fustini said.

He said he believed the couple who lived there also had two adult daughters living with them, and that the father worked at a nearby glass container factory.
