COURTLAND—Two Suffolk residents who were identified with the help of a lost merchandise tag pleaded guilty to multiple felony counts in Southampton County Circuit Court on Tuesday.

Angela Corrine Farley of York Street and Stefan Joel Ponzi of Manning Road were each convicted of two counts of grand larceny, two counts of breaking and entering and one count of possessing burglary tools.

In a one-night burglary jag, the pair stole metal items from businesses in a shopping area on Route 58 near Courtland. From Charlie’s Glass and Murphy Motors, they stole a large quantity of stock aluminum, including frames from uninstalled storefronts; a bicycle; paint; scales; aluminum tire rims; pressure washers; and the coil out of brand new air conditioner.

Police found the tag from a pair of bolt cutters on the scene and traced it back to the place of purchase, after which they were able to identify the purchasers and determine that they had been the burglars.

“There was good old-fashioned detective work in that case,” Southampton Commonwealth’s Attorney Eric Cooke said Wednesday.

Farley and Ponzi will be back in court Feb. 26 for sentencing.

Each could receive as much as 20 years for each of the burglary and grand larceny convictions, as well as up to 10 years for possession of burglary tools.
