Trivia: The code that Hank enters ("101097") is a reference to the original "Fallout" video game, which was released on October 10th (10/10) in the year 1997 (97).
Trivia: Elsbeth suspects that a "suicide" is actually a murder because the victim had recently used teeth whitening strips. This is similar to the last Columbo episode, "Columbo Likes the Nightlife", where the "suicide" victim has recently used mouthwash and trimmed his toenails. In each case they didn't believe a person would do those things right before taking his or her own life. Elsbeth also often turns around with "just one more thing" after walking away, just as Columbo often did.
