The boy was charged with murder Friday night, hours after 47-year-old cab driver Vincent Darbenzio was found shot in the head in Scranton. Police said he had complained the driver was "taking the long way and ripping him off."
The boy also claimed he had been a suspect in a Newark triple homicide.
But Newark detective Anthony Ambrose tells the Star-Ledger that police had interviewed him as a witness to the Christmas slayings of three teenagers, but he wasn't a suspect. A 15-year-old was arrested in that case.
