After that killing, detectives discovered the same gun was used in the fatal shootings of two other shopkeepers when ballistics matched the .22-caliber gun shell casings on all three. On July 6, Mohamed Gebeli, an Egyptian, was found shot at Valentino Fashion Inc. On Aug. 6, Isaac Kadare, also Egyptian, was shot in the head at Amazing 99 Cent Deal.
There were other similarities in the deaths, authorities said: The bodies were all partially obscured, by clothing or, in one case, a box. The locations of the shops form an equilateral triangle and are about 4 miles apart, with addresses that contain the number eight.
Police earlier this week said they were looking to speak to four people who possibly witnessed the most recent killing and released video and clear images of the four. But they zeroed in on the man with the bag, who they now say was Perrone.
Police said they believe Perrone carried the murder weapon in the bag and traveled by subway.
Perrone, a Brooklyn native, is divorced and lives with his girlfriend. He went store to store trying to sell clothing, police said, but it was unclear if he had tried to sell to any of the victims.
