Mark Zimmerman

The grisly murder and dismemberment of a New York cabbie draws the elite Special Victims Unit of the NYPD, including veteran Detective Elliot Stabler (Christopher Meloni, "Oz") and his partner, Olivia Benson (Mariska Hargitay, NBC's "ER"), who soon discover that the victim had assumed the identity of another man -- mainly because he himself was a wanted man. As they dig deeper, the pair draw a bead on the two likely killers (guest stars Mili Avital, "Kissing A Fool") whose tortured pasts explain their very personal reasons for hating the slain cabbie. Richard Belzer reprises his character of Detective Munch from NBC's "Homicide: Life On the Street." Dann Florek (reprising his role of Captain Cragen from NBC's "Law & Order"), Dean Winters, ("Oz"), an enthusiastic newcomer who worships the ground on which his partner Munch walks, and the street-savvy detective Monique Jeffries (Michelle Hurd, "The Practice") also star. Dick Wolf ("Law & Order") created the series. Angie Harmon ("Law & Order") guest-stars as D.A. Abbie Carmichael.

The Machine's latest number presents a unique challenge for Reese and Finch since the person has virtually no digital footprint and appears to be leading a double life.

A man is found dead in a seedy hotel, and it appears to be a perverse sexual encounter gone awry. It takes awhile but Briscoe and Green find the identity of the victim. First by tracing a phone call to a hooker named Cosette, then by talking to the manicurist near his hotel, who tells them the victim had been there a couple of days before he died and told the manicurist he drove around the country and was from Philly. They find his car, with a stack of clips about Mitchell Maas in the trunk. Maas is a bookstore heir and fugitive rapist, and the victim is "Bobcat" Rovelli, bounty hunter. They find his cell phone records that show he made three calls to Brian Kellogg, a star reporter for the venerable New York Tribune. African-American and young, Kellogg was on the fast track and had just done a controversial interview with Maas. But he refuses to give up his whereabouts.

The detectives discover a link between the deaths of an investigative reporter and his fiancee, organized crime and the governor's office.
