Appearing on the right

Terence Niebaum was an Internal Affairs inspector in The Negotiator. He was portrayed by J.T. Walsh.

He was responsible for the investigation of the theft of the police pension money.

He inadvertently betrayed his own police informant Nate, who came to him with wire taps and confronted the corrupt cops involved in it who bribed him to lose the evidence. He thought Nate would take the same bribe but didn't, causing his death on the way and igniting the events that later lead to the hostage situation, in which he was finally murdered by the corrupt cops so that he wouldn't talk, but only after he gave their names to Danny Roman and that he hidden the taps somewhere safe.
