Law enforcement sources say Perrone made statements placing himself near the scene of the shooting at the Valentino Fashion Inc. in Bay Ridge on July 6. Mohamed Gebeli, 65, an Egyptian immigrant and a Muslim, was found shot in the back of his shop. Detectives found .22-caliber gun shell casings at that crime scene and also at the scene where Isaac Kadare, 59, also Egyptian but Jewish, was shot in the head in his Amazing 99 Cent Deal store Aug. 6.
The latest victim, 78-year-old Rahmatollah Vahidipour, a Jewish man from Iran, was killed in his women's clothing boutique on Flatbush Avenue Friday. The same casings were found at that scene.
Authorities also found .22 caliber ammunition, three knives, one of which appeared to have blood on it, black gloves and women's pantyhose with the legs cut off in the duffel bag, a law enforcement official said. The blood on the recovered knife is being tested for DNA evidence.
Law enforcement sources say Perrone's girlfriend and ex-wife are cooperating with detectives. Sources say he is a fabric and garment salesman, and has several prior arrests, including for stalking and burglary, in Pennsylvania.
A woman who lived across the street from Perrone's former home on Staten Island said the divorced father of one was a peculiar neighbor and that he used to sing opera loudly from his front yard at odd hours of the night.
"He was just that crazy neighbor," said Julia Marra, 21, who nevertheless viewed Perrone as harmless.
It appeared Perrone was trying to sell his home on the corner of Clove Road and Beverly Avenue on Staten Island. The structure was visibly in disrepair and in need of rehabilitation Wednesday. A phone number listed on the for sale sign in the yard connected to a voice mailbox belonging to Perrone.
Detectives who specialize in hate crimes and FBI analysts who specialize in behavioral analysis joined the case this week, authorities said.
