* Warren White in ''ComicBook/ArkhamAsylumLivingHell'' used this trope against an employee who had discovered the accounting irregularities that proved that White had been embezzling funds from his investors. The employee didn't know that White had committed the crime though, and White didn't kill him. Instead, White pinned the crime on him and destroyed the only copy of the numbers, leading to the man killing himself.
* Subverted in ''Franchise/{{Batman}}'' comics -- Lucius Fox tells ComicBook/LexLuthor that he knows about Luthor buying large amounts of Gotham City for a fraction of the price, and informs him that yes, people know where he is and yes, he has made copies of the data. He still would have been killed by Mercy Graves if Batman hadn't been watching his back though.
* ''ComicBook/BatmanNoMansLand'': One ''Batman Legacy'' story has Bane getting sensitive information from an AlmightyJanitor in R'as al Ghul's palace. Bane doesn't want this information getting around, but doesn't want to kill anyone whose presence will be missed.

* From ''ComicBook/ExMachina'' [[GrandFinale #50]]: [[ParentalSubstitute Kremlin]], drunk and holding a gun to his own head, threatens to expose the fact that Hundred [[UtopiaJustifiesTheMeans used his powers to get elected as Mayor of New York]], thus killing his Presidential campaign. At first, Hundred tries to get him to put the gun down, then asks if he's shown the evidence to anyone. When Kremlin reveals he hasn't, Mitchell [[MoralEventHorizon tells the gun to fire]].
* ''ComicBook/FantasticFour'': In a flashback in Jonathan Hickman's run, the Supreme Intelligence of the Kree is talking with two scientists. As it analyses their proposed project, it starts getting increasingly worried. Once it stops analysing, it asks them if what they're brought is ''all'' their data. The two scientists, being schmucks, say it is, at which point the Supremor tells its Accusers to [[ThePurge get rid of them, and the data, and all the beings they experimented on]].
* An early ''ComicBook/MoonKnight'' story has an underling giving his boss a full dossier on Moon Knight and his various alternate identities. When the boss asks who else knows all this, the man almost cheerfully replies "me." Smirking "Good," the boss hits a button that literally opens a trap door to send the underling into a waiting pit of alligators.
* A dreamwalker tries to avert this in ''ComicBook/RisingStars'' when he finds out who'd been killing the other Specials. The killer, a Superman proxy, beats the tar out of the much weaker man and asks who else knows. The dreamwalker lies and says that he's told everyone... and is killed for his trouble. Luckily, a Special who could hear the recently deceased was able to get this information to another Special who had been investigating the murders as well.
* In ''ComicBook/SinCity'', after the escape from the Farm, Marv and Lucille are cornered by cops sent to the Farm. Marv wants to take them out, but Lucille, who is a cop herself, [[PercussivePrevention knocks him out]], telling him he's not going to get either of them killed. She then talks to the officers present about what is going on and finishes with "...so there's no reason to kill him." The head cop's response? "Yes there is, ma'am...once he's told us who ''else'' he's spoken to." Lucille is blown away moments later.
* One issue of the Creator/{{Dark Horse|Comics}} ''Franchise/StarWars'' comics set during the Clone Wars had a Jedi propose a plan to uncover the Sith Lord hiding in the senate, by having all senators, aides and ranking officials submit to a blood test to measure their Midichorian count. Unfortunately the only person this Jedi suggests this rather clever little plan to was Chancellor Palpatine. Whoops.
* An InvokedTrope in ''ComicBook/StarWarsDoctorAphra''. Aphra knows that [[LukeIAmYourFather Luke Skywalker is Darth Vader's son]] and that Vader is plotting to usurp the Emperor. In "The Catastrophe Con" she's being mind-probed on an Imperial PrisonShip, but gets hold of a transmitter and calls her LoveInterest, Imperial officer Magna Tolvan. When Tolvan says she can't help, Aphra tells her the big secret and points out that when she's finally forced to reveal that secret, the ''next'' thing the interrogators will ask her will be this trope, so Tolvan is forced to come and rescue her before that happens.
* A while ago in the ''Franchise/{{Superman}}'' books, a specialist for the CIA, using recently acquired alien language translation technology, was able to find out that the markings of a small craft that crash-landed in Kansas 30 years ago were Kryptonian. The man, being without friends or family, reported this to his direct superior, the President of the United States: Lex Luthor. One cut-away later, Lex nonchalantly tells his chauffeur to have maintenance clean up a "spill" on the carpet: a small red glob one can only assume is the man's remains.

* ''ComicBook/{{Transformers|2019}}'': During a stand-off between the Autobots and a group of Risers led by Ruckus, Senator Soundwave (who is secretly a high-ranking Rise member) arrives to ostensibly negotiate. He goes into the Rise hideout, promises to arrange an escape route for them, then [[SchmuckBait asks if any of them know anything of value]]. Ruckus is [[TooDumbToLive too stupid to catch the implication and blithely confirms that he does]]. Soundwave then casually makes an excuse to leave, and as soon as he's at a safe distance, he detonates the explosive spear he had snuck in with him, [[HeKnowsTooMuch killing everyone in the bunker to keep their knowledge out of Autobot hands]]. Unlike most examples of this trope, Soundwave was rather obviously trying to hint that Ruckus should say "no" and was visibly disturbed by their deaths afterword.

* ''Film/ToBeOrNotToBe''" When the Resistance fighters and actors disguised as Nazis prepare to kill a traitor, they subtly inquire about whether he's made a copy of the list of underground agents and families of Polish fighter pilots he's preparing to turn over. Unfortunately, he has, leading to a scramble to retrieve ''that.''

* ''WesternAnimation/MonstersInc''. After Mr. Waternoose hears the full story of the incident from Mike, he asks, "Does anyone else know about this?" It is a terrific moment due to the business headaches Mr. Waternoose has been dealing with since the opening of the film. The line seems innocuous enough and appears to be genuine concern on Mr. Waternoose's part right up until the Banishment Door shows up and he shoves Sulley and Mike through.

* In the Film/MissMarple film "Murder at the Gallop" (starring Margaret Rutherford), frightened Miss Gilcrest gives Miss Marple information regarding the murder of Mr. Enderby, and Miss Marple asks her if she's told anyone else the information. This is a subversion because Miss Marple is the detective investigating the murder and [[spoiler:Miss Gilcrest is the murderer trying to throw Miss Marple off track]].

* A case of this happens both ways in ''Series/Daredevil2015'', after Karen Page and Ben Urich interview Wilson Fisk's mother.
** The hero to villain variant happens first: Marlene calls James Wesley and informs him of Karen and Ben's visit. Wesley goes out, kidnaps Karen, takes her to an abandoned warehouse, and tries to blackmail her into backing down. She asks him if he's told Fisk about her involvement in visiting Fisk's mother. Wesley says he hasn't. Then Wesley's phone rings, as Fisk is trying to call him from the hospital. [[TheDogBitesBack Having been victimized by Fisk one time too many]], Karen grabs the gun [[TooDumbToLive Wesley had placed on the table]] and shoots him to death, guaranteeing that this doesn't happen.
** The villain to hero variant happens in the next episode, when Fisk learns about Karen and Ben's visit from his mole at the ''Bulletin''. Fisk breaks in to Ben's apartment, and asks Ben if there was anyone else there when he talked to Fisk's mother. Ben realizes that Fisk is eliminating loose ends, and will go after Karen if he mentions her. So he lies and says he was alone. Fisk then gets up, wrestles Ben to the floor, and chokes him to death with his bare hands. As a result, Karen is still alive, aware that Fisk killed his father, and blames herself for getting Ben killed.

* ''Film/TheDeep'': When salty treasure hunter Treece finds out that David and Gail have found a wreck he's heavily interested in, he asks who else knows about it. After a moment's pause, they truthfully reply that a local man named Bondurant has approached them about the wreck. However, it quickly becomes clear that Treece is a hero (or at least an AntiHero) and Bondurant is a ruthless crime lord.

* Creator/VernorVinge's ''Literature/ZonesOfThought'': In ''Literature/AFireUponTheDeep'', Scriber, a somewhat flaky inventor and self-proclaimed spy, comes up with a method of locating enemy spies in Woodcarver's city. He tells it to spymaster Vendacious, not realizing he's a double-agent and that Scriber's method would expose him. Vendacious congratulates Scriber and asks who else knows about this because "we'll need to swear them to secrecy also". Needless to say, after Scriber's earnest assurance that no-one else knows, death follows rapidly.

* In ''Film/MissionImpossibleDeadReckoningPartOne'', Denlinger, the Director of National Intelligence, meets with Gabriel, TheDragon of powerful artificial intelligence and BigBad the Entity, to inform Gabriel that he has made sure nobody but him knows the location of the ''Sevastopol'', a submarine that was attacked by an early version of the Entity’s program and thus may give its enemies an opportunity to find a weakness. Denlinger thinks that this intelligence makes him useful to Gabriel, but since Gabriel is fine with the submarine’s location staying secret due to his twisted loyalty to the Entity, he simply confirms that nobody else knows where the submarine is and then kills Denlinger.

** ''Literature/{{Allegiance}}'': Ominous StateSec official Vak Somoril asks Captain Ozzel who else knows about a secret that could sink their careers in one scene as part of a plot to commit murder. Unusually, Somoril isn't planning to kill Ozzel except in a worst case scenario, but plans to kill anyone else who knows the secret and is below a certain rank. Ironically, Ozzel asks Somoril if ''he's'' told anyone else while listing eveyone in the loop, but asks that question innocently and lacks the backbone to ever dream of trying to get the better of Somoril.
