CLEARFIELD TWP — A 17-year-old girl is accused of deliberately setting three fires in 10 days at her parents’ family farm on Shuler Road.

State police Wednesday charged the teenager, who they did not identify, with three counts of arson.

“She confessed to all three fires,” said Trooper Brian Crouch of the state police fire marshal’s office.

Investigators have a general idea but no specific motive to explain what drove her to set the fires, said Cpl. Jeff Crede, the state police marshal in Butler.

“We identified some anger issues,” Crede said, “as a possible motive for setting the fires.”

The girl, an 11th grade student at the Clarence Brown School in Butler Township, is charged in Butler County juvenile court.

Investigators said the girl was 16 when she allegedly set the first two fires. She turned 17 just before the third fire.

She used matches to ignite all three fires, Crouch said.

Police suspect she first set fire to a barn April 9 on the farm owned by her 62-year-old father, Harry Snyder III.

A day later, police said, she intentionally set fire to the house where she lived with her father and mother, Debbie, an older brother, 27-year-old Harry Snyder IV, and a younger brother.

The fire destroyed the house, forcing the family to move in with Harry Snyder’s mother, Rose Snyder, whose house is close by on the farm.

Police believe the girl on April 19 set fire to that house, too. But that fire, caused only minimal damage to a bedroom.

Combined damage in the three fires exceeded $200,000, authorities said. The property is insured.
