A former NYPD detective who was caught lying when a murder suspect recorded the cop questioning him on an MP3 player was sentenced to four months in in jail. Christopher Perino has already lost his job, pension and health benefits, estimated to be worth $3 million, after being convicted for perjury. Perino had claimed to have never questioned 17-year-old attempted murder suspect Erik Crespo during Crespo's trial, only to have the teenager break out the hour-long grilling he had stored on file.
