Tonight Anderson Cooper 360 features a documentary, "81 minutes: Inside the Greatest Art Heist in History" at 10 p.m. ET (US). The show claims an exclusive television interview with Richard Abath, the night watchman who admits he was the guard on duty who "buzzed in" the two thieves disguised as police officers.

The segment also includes Anthony Amore, Security Director of the ISGM, walking journalist Randi Kaye through the known events of the 1990 theft in the early morning hours of March 18.
