A Hempstead man was convicted Friday of snatching two women's purses at gunpoint in the parking lot of a Westbury Costco last April.
Randy Summerville, 32, could face up to 25 years in prison when Judge Alan Honorof sentences him April 8.
Prosecutors said Sumerville was found guilty of two counts each of first- second- and third-degree robbery and third-degree criminal possession of a weapon. He was found not guilty of two counts of first-degree robbery and one count of second-degree criminal possession of a weapon.
His lawyer, Steven Raiser, of Mineola, said his client intends to appeal.
Prosecutors said Summerville pushed a woman into her car as she opened the door, at about 11 a.m. April 9, 2012, then grabbed her purse off the passenger seat. He then pointed a silver handgun at her and tried unsuccessfully to take another bag, which she was holding by a strap, prosecutors said.
While fleeing the scene, Summerville pointed his gun at a second woman, prosecutors said. When the woman placed the purse on the ground, Summerville picked it up, and then got into the passenger side of a waiting red Ford Explorer, prosecutors said.
The suspected driver of the car is awaiting trial.
