Two former New York Police Department detectives were sentenced to life in prison without parole Friday for operating as Mafia hit men while employed by the NYPD. According to prosecutors, the detectives were paid $4,000 a month by the Mafia and were personally paid $65,000 by Luchese crime family underboss Anthony "Gaspipe" Casso for killing another mobster during a phony traffic stop. Although they reiterated their innocence at Friday's sentencing, the two detectives were found guilty of participating in or aiding eight murders, two attempted murders and one murder conspiracy, as well as witness tampering, witness retaliation, obstruction of justice, money laundering and drug charges.
