A contractor hired across Suffolk County is facing grand larceny charges, accused of stealing more than $30,000 from clients.

According to a release from Suffolk police, a 75-year-old woman reported to police on Aug. 29, 2023 that she had hired Olger Conce Guambana to do work at her home “and it was not completed as agreed.”

“Conce Guambana then used a bad check to issue a partial refund and stopped all further communication with the woman,” it says.

According to court documents, the defendant stole from clients in Bay Shore, Port Jefferson, Centereach and Lake Grove.

Additionally, the defendant is accused of theft at Sider Lumber in Nesconset. Joseph Sider told News 12 that the defendant paid for items worth about $5,000 with two checks but then stopped payment on the checks.
