Collective (S04E12)

Arnold Pierce (Jordan Gelber) is a very nervous sci-fi toy collector. He sees a listing for a 1950's sci-fi TV-show robot online and gets very upset. He goes to a toyshop in Philadelphia to try and buy it, but the storeowner insists it has to be purchased through the online auction. Shortly thereafter, officers are called to Pierce's apartment, where they hear a woman screaming inside. When they burst in, he has a silver toy in his hands; the cops think it's a gun and shoot Pierce dead. The alleged hostage is nowhere to be found, and detectives realize that it may have been a setup. Detectives Goren (Vincent D'Onofrio) and Eames (Kathryn Erbe) figure out that Pierce had been ripped off. Someone stole a very expensive, collectable robot from him and he was trying to get it back.
