Soldier of Fortune (S12E04)

Two people are shot on the sidewalk and a diamond dealer is kidnapped. The suspects escaped in a van and the victims were shot by Uzi machine guns. A black man, whose car blocked off the intersection for the van driver, escaped into a subway station. The deceased are a banker, John Hammins, and a mother of two, who was out shopping for a diamond ring. Hammins also apparently tried to assist the kidnapped victim. The man who was kidnapped is identified as Richard Powell, a diamond dealer. His wife and father anxiously await word from the kidnappers, but they hear nothing. Then they get a call that the van has been found. Powell is dead, his hand severed and his throat cut. Briscoe (Jerry Orbach ) and Green (Jesse L. Martin) are able to recreate Powell's last stops, and realize he met Hammins at a bank near the crime scene. (iTunes)
