'Son of Sal' Kills Three Shopkeepers Around New York City

In the summer of 2012, Salvatore Perrone, dubbed "Son of Sal," killed three New York City shopkeepers — Mohamed Gebeli, 65, Isaac Kadare, 59, Rahmatollah Vahidipour, 78. Each murder was committed near closing time, and .22-caliber shell casings were recovered at the crime scenes. Vahidipour's daughter, Marjan Vahidipour-Malekan, remembers her father and the case.
