Investigators have not been able to determine the cause of the Christmas Day house fire in Dushore which claimed the life of 75-year-old Louis Repetto, a state police fire marshal said on Thursday.

The extensive damage to Repetto's residence, which is located off School Street, has made it difficult to determine the cause, said State Police Fire Marshal Ronald Jarocha, who is based at the state police's Wyoming barracks.

It's possible that the fire was started by a wood stove, he said. However, due to the extensive damage, investigators don't know if the stove played a role in starting the fire, he said.

The cause of the fire is currently listed as "undetermined," he said.

The fire destroyed Repetto's house.

Dushore firefighters were dispatched to the residence at 6:54 a.m. on Dec. 25, where they found fire throughout the rear of the building.

Firefighters made several attempts to search for Repetto, but had to turn back due to unsafe conditions, John Yonkin, first assistant chief of the Dushore Fire Company, has said. Repetto's body was recovered Wednesday afternoon from inside the building.

Repetto lived alone in the residence.
