(CBS/AP) NEW YORK - Police are searching for a gunman who they say has used the same weapon to kill three Brooklyn shopkeepers since July.
All three victims were of Middle Eastern descent. Their stores are within a 5-mile radius, and none of them had surveillance cameras.
Rahmatollah Vahidipour, 78, was killed at his store, She She, in Brooklyn's Flatbush section on Friday. Police said he suffered gunshot wounds to the head and torso.
Police said that ballistics evidence connected the same gun to the shooting deaths of two other Brooklyn shopkeepers over the summer.
Clothing store owner Mohamed Gebeli was killed inside Valentino Fashion in Bay Ridge on July 6. Isaac Kadare was found dead on Aug. 2 at his Amazing 99 Cents Deal shop in Bensonhurst.
Police said they don't know the motive behind any of the killings. Authorities are offering a reward of $22,000 for information leading to an arrest and conviction in the three homicides.
