7x16 - Law & Order

Back in New York with their suspect, Briscoe and Curtis try to pin down his schedule on the night of the murder, but find instead that another man was in the area at the right time and more importantly, might have a motive for the crime. But after the issuance of a new arrest warrant, McCoy and Ross have to fly to LA to defend their warrant against attacks by the man's defense counsel, Ross's former husband Neal Gorton.
