In a law enforcement procedural show, when the criminal gets away with murder or a similarly heinous crime, like serial rape (either through skill on his part or mistakes on those of the cops or the lawyers) but gets killed before the end credits roll, usually in a VigilanteExecution.

A subtrope of KarmicDeath. Often goes with SerialKillerKiller. Often similar to DeusExMachina. See also OffOnATechnicality for how they get out, and VigilanteMan for the sort of guys who kill this sort of guys. If the cause of death was a method that the killer/victim employed, it becomes a HoistByHisOwnPetard.

In {{Revenge}} or RoaringRampageOfRevenge stories, making the killer the killed is the main goal of the protagonist, though he or she should be careful that he or she doesn't fall on the [[HeWhoFightsMonsters wrong side of the trope]] as well.

!!'''As a DeathTrope, all Spoilers will be unmarked ahead. Beware.'''


[[folder: Anime and Manga ]]

* Light Yagami of ''Manga/DeathNote'' has murdered hundreds, if not thousands, over the course of the series with the titular ArtifactOfDoom, only to be killed by the very deity that gave him the Death Note by making good on his promise to write Light's name in it.
** Heck, none of the Kiras meet very pleasant fates. Two heart attacks, two suicides, and one burning to death, and that's before you consider the general misfortune they met with up until then.
* This is the backstory behind some of the victims of the week in [[DetectiveConan Detective Conan]], with the motive of the culprit who murdered them being to avenge a death of a loved one which the [[AssholeVictim victim was responsible for]].
* Luciano Bradley in ''Anime/CodeGeass'' makes a career out of killing his opponents. Imagine his surprise as he gets incinerated by Kallen.
* A {{jerkass}} cyborg in ''Anime/GhostInTheShellStandAloneComplex'' who got off a murder charge after turning the court case onto Togusa using excessive force for being 'prejudiced towards cyborgs'. The episode ends with a secretary on night shift watching a news report of both the man and his attorney having died in a hit and run car crash, while Boma enters from the car deck, informing her she needs to arrange the disposal of a damaged car.
* In ''[[LightNovel/KaraNoKyoukai Garden of Sinners]]'', this is subverted with Fujino but played straight with Lio.
* Happens every time an unlucky criminal gets in Revy's way in ''Manga/BlackLagoon''. Most notable is her battle with Ginji Manslayer who is about the only character (other than Roberta) who stands a chance against her. In their final fight, his focus slips for a fraction of a second and she seizes that instant to kill him. Another good example is Hansel and Gretel, although they're offed by the Russian mob.
* Happens commonly in ''Anime/HellGirl'' if being dragged to Hell counts as being killed.
* In ''Manga/{{Bleach}}'', Shrieker was a serial killer in life and spent his time as a hollow using the kid who killed him the first time to kill more people by using him as bait. Bad news for him, [[BerserkButton he mentioned he killed the kid's mother in front of Ichigo]] and ended up being sent to Hell for a fate even worse.


[[folder: Comic Books ]]

* ''ComicBook/SinCity'':
** Kevin is a PsychoForHire / SerialKiller who murders [[ImAHumanitarian and eats]] a number of women, before meeting his own gruesome end at the hands of SociopathicHero Marv.
** Roark Jr. aka "That Yellow Bastard", who was a serial killer and rapist of little girls, is castrated AND beaten to death by John Hartigan.
* There are not many killers who survive meeting ThePunisher.
* Likewise, there's a reason why the Comicbook/GhostRider has supernatural villains in his RoguesGallery, the human ones don't tend to escape his punishment..


[[folder: Films -- Animated ]]

* ''WesternAnimation/CorpseBride'': No one bothers to interrupt Barkis' gloating over getting away with killing Emily to warn him that the goblet he uses to toast her is actually filled with poison, not wine.


[[folder: Films -- Live-Action ]]

* In ''Film/NewJackCity'', Nino Brown, a drug kingpin, almost gets away scot-free, when he's shot down by an old man who lived in the projects Nino took over to sell crack out of. Very dramatic, when the old man cries out "Idolater... your soul is required... in HELL!" and pulls out his gun and shoots Nino to death. As for the fact that Nino was on the escalator heading down, while the old man was on his way up the escalator next to him... [[FauxSymbolism What Do You Mean It's Not Symbolic?]]
* This is also how ''Film/LAConfidential'' ends. Ironically enough, the victim asks his executioner at the start of the film if he's prepared to shoot a hardened criminal in the back to prevent him being acquitted. Guess how the Vic dies?
* Subverted in ''Film/{{M}}'', in which the serial child killer barely manages to be arrested, rather than killed.
* In ''Film/SuspectZero'', Ben O'Ryan is a [[SerialKillerKiller serial killer who hunts down and murders other serial killers]] through telepathic "remote viewing".
* In ''Film/DiamondsAreForever'', a diamond smuggler tries to dispose of an MI6 agent on his tail. The MI6 agent kills him in a fight that mostly takes place inside an elevator, puts the diamonds in his body, and takes him to Slumber, Inc. in Los Angeles to be burned.


[[folder: Folk Music ]]

* The plot of the folk ballad "The Outlandish Knight" and its variations: "For six pretty maidens hath thou drown'd here/the seventh hath drownéd thee"


[[folder: Literature ]]

* In Creator/AgathaChristie's ''Literature/{{Murder on the Orient Express}}'', this was the killer's motivation. Or, rather, the ''killers'.''
** ''Literature/{{And Then There Were None}}'' also has this as the killer's motivation.
*** Notable in that killer, though innocent before the events of the novel, recognizes that he is now a killer himself, and takes the only appropriate (for the trope) action.
* In the SherlockHolmes story "Wisteria Lodge", the killer escapes but is later murdered in Madrid. A couple of other stories close with hints that this trope may have occurred.
** The Case of the Speckled Band crosses this with KarmicDeath.
** And Charles Augustus Milverton (although he was a blackmailer)
* ''Regina's Song'' is about a girl who hunts down and kills the man who raped and murdered her twin sister (Along with a dozen or so other sexual predators who cross her path).
* Ms.Gee the sybil in ''[[Literature/{{Dragons}} Dark Fire]]''.
* In the novel and FilmOfTheBook, ''Literature/ThePostmanAlwaysRingsTwice'' Cora and her lover and her lover Frank [[AmmoralAttorney get away with]] murdering her husband via a staged car accident. At the end, Cora and Frank get in an actual car accident which kills her, and Frank is convicted and on death row for her "murder". The DA tells him that even if he wasn't charged for Cora's "murder", new evidence showed that he took part in Nick's murder, so there would be no point in trying to fight it.
* Creator/RudyardKipling: In "[[Literature/TheJungleBook The King's Ankus]]" Mowgli deduces that the second thief of the ankus, after killing the first, surreptitiously poisoned the third through sixth thieves' meal before being killed by one of them, and so they all ended up dead. (Kipling apparently stole this idea from one of ''Literature/TheCanterburyTales'').


[[folder: Live Action TV ]]

* ''Series/{{Dexter}}'' is full of killers that were never brought to justice. And Dexter is [[SerialKillerKiller the guy making sure that they die anyway]].
* Every ''Franchise/LawAndOrder'' has a bunch of these. Some of them even well set up.
* {{Inverted|Trope}}: In an episode of ''Series/{{CSI}}'', a criminal who the police have found clear evidence shot a teenager as he fled a shootout with the police in order to use his bike as a getaway vehicle is shot by a member of a rival gang as the police lead him away. The trope is otherwise played straight.
* At the end of the second season of ''Series/VeronicaMars'', Aaron Echolls manages to get acquitted of the murder of Lilly Kane, mostly by virtue of the fact that he's, well, a famous movie star. He proceeds to spend the rest of the episode being smug at both Veronica and his son Logan, implying to both that he'll be around to antagonize them for a long, long time. Finally, he stumbles across one of his old movies on TV in his hotel room and seconds later is promptly shot in the back of the head by Clarence Wiedman, on orders of Lilly's brother Duncan (who Ecchols had accused of being the real killer, no less).
* In the Season 3 finale of ''Series/TheKilling'', Linden discovers the serial killer of young girls she's been chasing all along is her own ex-partner (and lover). Following a lengthy conversation where he attempts to explain himself, she shoots him dead, in cold blood.
* A variation of this trope is one of the ways a ''Series/{{Columbo}}'' TV movie mixed up the formula a little. The killer the viewer follows from the beginning attempts to kill his rich uncle, but the uncle dies before his death trap is sprung... which kills the gardener instead. He eventually figures out who actually killed his uncle (his aunt), and attempts to blackmail her. [[BlackmailBackfire Like most people who try to blackmail a murderer]], [[TooDumbToLive he fails to realize that if she already killed one man, she's not going to have much problem with killing another...]]
* Gibbs once invoked this on ''Series/{{Ncis}}''. Evidence pointed to a gang leader having been killed by his second-in-command (also the killer of the week), who was still claiming to receive orders from him. They don't even have a body, and Director Shepard says that there's not enough evidence to convince a jury. Gibbs answered "That depends on what jury" and presented the information (about the gang leader, not the other murders they were investigating) to the other members of the gang. The killer is dead within hours.
* ''Series/TheOuterLimits1995'': The episode "Judgment Day" was about an ImmoralRealityShow in which convicted murderers are released so that the family members of their victims can hunt them down and kill them on national television. This is subverted in the case of the protagonist, both because he's been framed and manages to convince the person who's hunting him that he didn't kill her sister, but played straight in the case of [[spoiler:the T.V. show's producer, who is responsible for the FrameUp and then kills the other sister as well to cover it up. The protagonist later hunts the producer down as after he's been exposed and become a target on his own show.]]


[[folder: Mythology and Religion ]]

* From Myth/ClassicalMythology, the hero Theseus on the road of Athens rid it of six murderers by killing them the same way they had murdered their victims.


[[folder: Video Games ]]

* The principal antagonist in the video game ''VideoGame/CondemnedCriminalOrigins'', is an embodiment of this trope. A serial killer who only targets other serial killers, killing each using their own quirky M.O. He goes through MotiveDecay and kill two cops, frames the player character for it (and later plans to brutally kill the hero), then kills his own uncle and the mayor in the sequel.
* Ragou and Cumore from ''VideoGame/TalesOfVesperia''. Ragou abducted people's children when they failed to pay his cripplingly high taxes and fed said children and many others to monsters. Cumore fooled people into working to death in slave labor camps and sent people on suicide missions hunting for a giant monster. Both got away with it due to being high ranking nobility... until [[TheHero Yuri]] [[VigilanteExecution slashed Ragou across the chest and pushed his body into the river.]] Later on, [[VigilanteMan Yuri]] [[CruelAndUnusualDeath led Cumore by sword point into a quicksand bog where he was buried alive.]] In both cases it's [[CrowningMomentOfAwesome Awesome]].
* Hermes from ''VideoGame/TheSuffering'' is a very interesting take on this. As a prison executioner, he made an entire career murdering people in different ways, but he stated that he was the only one focused enough to get the job. In fact, he was so focused that he gassed himself in the chamber, just to have knowledge of both sides of the "experience".
* Every single boss fight in the ''VideoGame/NoMoreHeroes'' series, what with being a series about assassins killing each other. Exceptions to Shinobu, Henry and Destroyman the first time. Kimmy also lives, [[BonusBoss assuming Travis even fights her]], and Holly Summers as well, but she kills herself.
* {{Defied|Trope}} in ''VideoGame/AnarchyReigns''. Max killed Jack's daughter and he's plenty mad about it. Leo talks him out of it.
* {{Averted}} and {{subverted}} in ''VideoGame/{{Persona 4}}''. The real killer [[spoiler:Adachi]] lives but willingly agrees to spend the rest of their life in prison, completely defeated. However, you never reach this point if you choose to kill [[spoiler:Namatame]], who your team ''thinks'' is the killer, thus the {{subversion}}.
* In the Thieves Guild quest line in ''VideoGame/TheElderScrollsVSkyrim'', the leader of the Thieves Guild, Mercer Frey, is out to avenge the death of the former guild master Gallus by killing Karliah, the one he blames for betraying and killing him. But in truth, [[spoiler:Mercer was the one who not only killed Gallus, but is at the heart of the Guild's hard times, having stolen the Skeleton Key of Nocturnal and used it to make a tidy profit at the Guild's expense]]. Once the true traitor is revealed, the final quest involves not only killing said traitor, but [[spoiler:making amends for his crime by returning the Skeleton Key to Nocturnal]].
* Case 3 of ''VisualNovel/DanganRonpa'' is discovered to have happened this way, where Yamada murders Ishimaru on Celes's orders, but is then killed by Celes herself later on.
* ''VideoGame/DarkSouls'': {{Invoked}} by the Blade of the Darkmoon covenant, whose members invade and kill players who have invaded and killed others. If you decide to be an invader in ''Dark Souls'', be prepared to have these guys on your tail.


[[folder:Visual Novels]]
* ''Franchise/AceAttorney'':
** In the fifth case of ''VisualNovel/AceAttorneyInvestigationsMilesEdgeworth'', the victim is Manny Coachen, ironically killed by the man who ordered him to murder Cece Yew ten years ago.
** In the second case of ''Ace Attorney Investigations 2'', the victim was found guilty of the murder in Case 1 and was killed in jail.
** Happens in the fifth case of ''VisualNovel/PhoenixWrightAceAttorneyDualDestinies'', though in a special case, as he is shot in the end of his breakdown by an unknown assailant. Subverted, though, as he survives.
** In the third case of ''VideoGame/DaiGyakutenSaiban'', the killer is murdered by the son of the victim.
** The first killer in ''Dai Gyakuten Saiban'' becomes the first victim of the sequel.
