Three people have been charged in connection with a Stewart Manor gas station robbery Saturday night in which the attendant struggled with one suspect, Nassau County police said.

Those charged were identified as Jason Kroll, 32, of Garden Place, Shirley; Heather McCormack, 27, of Floradora Dr., Mastic; and Christopher Giardiello, 26, of Walnut Place, Mattituck.

All were charged with robbery and grand larceny. Giardiello also is charged with possession of a dangerous weapon. Kroll also is charged with obstruction of breathing. At arraignment Sunday at First District Court in Hempstead, McCormack was held with bail set at $25,000 cash or bond. The other two suspects had not been arraigned yet.

Police said the robbery occurred at 6:05 p.m. at the Express Gas Station at 600 Tulip Ave. According to detectives, the three suspects pulled into the gas station and asked the male attendant for assistance with their Jeep Cherokee.

Police said that while Kroll spoke to the attendant near the vehicle, McCormack was in the driver’s seat and Giardiello entered the store. When the attendant re-entered the store he confronted Giardiello, who was armed with a knife and had cash from the register.

A struggle ensued during which Kroll grabbed the victim from behind, trying to strangle him, and allowing Giardiello to flee the scene with the proceeds, police added. A second male employee came to assist the victim and was able to detain Kroll until police arrived.

Fifth Precinct officers located McCormack and Giardiello at Meacham Avenue and News Avenue in Elmont where they conducted a vehicle stop and placed them under arrest.

Police said a subsequent investigation found the three suspects were also allegedly involved in a March 26 larceny at OK Gas Station at 66 New Hyde Park Rd., Franklin Square.
