State police and Westmoreland County detectives are conducting a criminal investigation into the fire that killed a 48-year-old Manor woman Sunday.
District Attorney John Peck would not say whether the death of Rebecca Kint, who also used the last name Sicchitano, was a homicide.
The early-morning blaze caused $110,000 in damage and gutted the two-story frame house on Harding Street, which overlooks Route 993.
"We've been investigating it since the time of the fire," Peck said. "I can't comment if you're asking me if it's a homicide. All I can say is it's under investigation."
Neighbors said investigators questioned one person outside the house at 7 a.m. Sunday, but Peck would not comment.
"Right now, it's just an investigation," he said.
Coroner Ken Bacha has not released the cause and manner of death for Lint, whose body was badly burned. He also has not ruled whether her death was an accident or the result of foul play.
Yellow police tape still surrounded the house Wednesday, and debris from the fire littered the yard.
Flames appeared to have spread from the back of the house toward the front, gutting the first and second stories. Kint's body was found in the rear of the house.
Kint, who was born in Charleroi, lived in the home with her fiance, Larry Haubrich, who could not be reached for comment yesterday. She has two daughters and a son.
Kint was a graduate of Pittsburgh Beauty Academy, worked as a caretaker for the elderly and formerly worked at a Hempfield personal care home.
