State police are investigating a theft of a check worth $40,449 from an Evans City-based contractor.

GBL Construction wrote the check and mailed it to a vendor who reported that its money was not received, according to a news release issued by state police last week.

According to the police report, the check was later discovered to have been cashed in July at a local bank, with the name “Almbraya Thompson” written where the name of the vendor was originally printed.
