!!Examples (spoiler alert!):

* This is how ''Series/{{Columbo}}'' solves a significant number of his cases.
* "Dead" from ''Series/LawAndOrderCriminalIntent''
* "Mr. Monk Goes Back to School" from ''Series/{{Monk}}''
* Invoked in an early episode of ''Anime/{{Pokemon}}''.
* On ''Disney/TheAristocats'' Edgar has to retreive his hat, umbrella and basket from {{Angry Guard Dog}}s Napoleon and Lafayette, lest the police find them and link him to the kidnapping of the cats.
* In the first ''AceAttorneyInvestigations'' game, Jacques Portsman returns to the scene of where he killed Buddy Faith, although it's justified, as he does so under the pretext of investigating the crime, trying to frame Gumshoe and then Maggey for the crime.
* Invoked by a WorldWar2 German propaganda poster produced for occupied France after a heavy bombing attack on Rouen by the Royal Air Force. It showed JoanOfArc at the stake above the silhouette of the burning city with the legend: ''Les assassins reviennent toujours ... sur les lieux de leur crime'' "The murderers always return ... to the scene of their crime".
* In the ''{{Talkartoons}}'' short "The Herring Murder Case", Bimbo looks in his detective book and reads a passage saying that the killer always returns to the scene of the crime, which gives him the idea to hide in the room and wait for the killer to come in so he can capture him.
