A weekend fire that killed a young boy who became trapped inside a Chester County house has been ruled accidental.

The blaze broke out in the house on the unit block of Buckwalter Road in East Coventry Township about 5:30 a.m. Sunday, according to Pennsylvania State Police.

When fire crews arrived, the house was “fully involved” in flames and the child was trapped inside, police said.

Firefighters pulled the boy, whose name has not been released, from the burning home. He was pronounced dead at the scene.

Officials said the fire started in the home’s kitchen.

Police did not release any other information about the fire or the victim.

The child was believed to be 9 years old, Ray Kolb, chairman of the board of supervisors in East Coventry Township and assistant chief of Ridge Fire Company, told the Reading Eagle.

Kolb said the boy’s father went on the home’s roof and tried to reach his son by breaking a bedroom window. The father suffered a severe cut to his arm.
