Police: Teen charged with cabbie's murder had been interviewed as witness to triple homicide

Police say a 16-year-old charged with fatally shooting a Pennsylvania cab driver who didn't take his preferred route was interviewed as a witness to a triple homicide in New Jersey last year.

Aazis Richardson 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 Richardson had complained the driver was "taking the long way and ripping him off."

Richardson also claimed he had been a suspect in a Newark triple homicide.

But Newark detective Anthony Ambrose tells the Star-Ledger (http://bit.ly/1nngJvJ) that police had interviewed Richardson 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.

Richardson is being held without bail. It's unclear if he has a lawyer.
