Gregory Russell Cook

Danny and Maria investigate a local bombing, but are met with tension and resistance from the community during the investigation. Meanwhile, Frank must deal with the political fallout when a man punches an officer who was overly aggressive in his questioning.

A young man is found stabbed to death outside a pizza parlor, with no identification. Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) soon learn, however, that he is Andrew Hatcher, an NYU student. Hatcher's grieving parents claim they got a call from him on his cell phone hours after the estimated time of death, but it turns out someone else made the call. Tracing the cell phone, they find a drug dealer named Jimmy Gaines (Gregory Russell Cook), who has Andrew's watch too. But he insists that he found Andrew's possessions in a dumpster. The police then find a blue denim shirt with blood on it nearby, but there is no trace of Jimmy's DNA or prints on it, so he is in the clear. They did find bovine blood on the shirt though, and the M.E reports that Andrew was stabbed with a six inch butcher's knife. They deduce that the killer worked in the nearby meat packing district.

One of New York's oldest family of criminals, the Boorlands, go on a crime spree that has the detectives running all over the city. When Walsh (Jeremy Renner) and Shraeger (Amber Tamblyn) learn the surprising reason behind the family's cluster of crimes, they use this information to negotiate its end. Meanwhile, Sergeant Brown (Terry Kinney) tells Shraeger that Walsh's former partner, Kowalski, was a dirty cop and asks her to dig into Walsh's past; and Cole's (Adam Goldberg) efforts to keep his criminal past a secret are threatened by the arrival of Frank Lutz (Ryan O'Nan), Cole's former partner in crime, on "The Unusuals."
