An Ulster County, N.Y., man was charged with altering a home heating oil receipt to support a $20,000 insurance claim for damages to a home in Kingston.

Gilson DaSilva, 50, is accused of altering the receipt to show that there was oil in the home’s furnace and that the residence was heated. The home, which was insured by DaSilva, was damaged by water when a frozen pipe broke in February.

New York State Insurance Department Frauds Bureau Investigator Valerie A. Burke said an investigation showed that DaSilva changed the address on a receipt for oil that had been delivered to another home. Investigators for DaSilva’s insurer, Central Mutual Fire Insurance Co., found that the oil tank was empty in the home that was damaged, according to the insurance department.

This finding allegedly contradicted DaSilva’s claim that the home was heated and that the damage resulted because the furnace malfunctioned.

DaSilva is charged with criminal possession of a forged instrument and falsifying business records. He could be sentenced to up to seven years in prison, if convicted.
