Detectives said they found the duffel bag at his girlfriend’s home. Inside, they said, was a sawed-off rifle used in the killings, along with .22-caliber ammunition, block gloves, women’s clothing, a bloody knife and a bottle of bleach.
Perrone’s fingerprint was lifted from the murder weapon, Kelly said. Initially, authorities thought the killer might have targeted the Brooklyn shopkeepers, who were from Iran and Egypt, because of their Middle Eastern backgrounds. But on Wednesday Kelly said there was no motive he could speak of.
In the most recent killing, Rahmatollah Vahidipour, an Iranian, was shot three times in the head and chest at his store, the She She Boutique.
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 said they believe Perrone carried the murder weapon in the bag and travelled by subway.
