Commonly seen in crime dramas, especially of the noirish variety, this occurs when a character or characters, having committed one crime, perhaps one not even that serious, must then commit another crime to cover up the first, and so on, leading to an escalating series of crimes set off by what may have originally been just an accident. If the character had just come clean at the beginning, he might have gotten off with a relatively light sentence. After a little while with this trope, he's looking at death row if he gets caught.

A tendency to encourage this is what makes AllCrimesAreEqual a Very Bad Idea. Compare SnowballLie, JumpingOffTheSlipperySlope and UnintentionallyNotoriousCrime. Contrast RevealingCoverUp. A major cause of NeverOneMurder and PlethoraOfMistakes...

[[folder: Comic Books ]]
* Steve Ditko's ''MrA'' stories always revolved around this, the Objectivist moral being that there's no such thing as toeing the line between good and evil.
* Jean Loring did this as part of DC's ''[[CrisisCrossover Identity Crisis]]'' storyline in which she set up a murder and an attack in order to cover up her own accidental killing of Sue Dibny.
* '' SinCity'': This happens from time to time, most notably Dwight [=McCarthy=] stories since he regularly gets in more and more trouble and technically has to break another law in order to get out of it.
* A recurring plan in {{Comicbook/Starman}} is a CorruptCorporateExecutive hiring a SuperVillain to go on a crime spree to cover up a single, financially motivated murder.

[[folder:Film]]
* Basically the entire plot of ''Stag'', in which the party-goers, having committed two counts of manslaughter in the second degree, spend the rest of the film debating whether to commit first degree murder in order to keep a witness from talking.
* The trope description doubles as a plot synopsis for ''Film/VeryBadThings''.
* ''Film/ASimplePlan'' is a rather harrowing example of this plot.
* In the black comedy ''Film/BigNothing'' Simon Pegg's character convinces David Schwimmer's character that nothing could go wrong with their plan to blackmail a local Reverend. Unfortunately no-one is quite what they seem, and soon one thing leads to another...
* ''Film/ThelmaAndLouise''. What starts as a act of self-defense ends with a multi-state manhunt.
* In Otto Preminger's ''Where the Sidewalk Ends'', a RabidCop accidentally beats a suspect to death, and ends up inadvertantly framing an innocent man while trying to throw suspicion off himself.
* The whole film ''Armored'' is basically a big example of this trope. The main plot starts off with a plan by a group of six or so armored truck drivers to steal the money they're transporting. The protagonist has more of a conscience than the average felon, but needs money and agrees to go along with it. Things start out alright for them when they take the truck to an abandoned warehouse where they plan to hide the money and then retrieve it after they pretend their truck was attacked. At some point, they decide that they need to blow up the truck in order to hide the evidence, but things still look like they might go off without any major hitches. However: [[spoiler: it turns out that a homeless man is living in the warehouse. When the homeless man sees them, the trigger-happy member of the heist team shoots him. When the protagonist suggests calling an ambulance, the team's leader finishes off the homeless man. Then, the protagonist [[HeelFaceTurn turns on them]] and sounds an alarm that draws a police officer to the warehouse. The trigger-happy guy shoots the cop, seriously wounding him. Then, in order to force the protagonist to cooperate with them, the crooks kidnap a member of his family. Meanwhile, another member of the team decides he can't handle it anymore and says he wants out, to which the other criminals respond by murdering him. In the end, the gang's leader tries to run over the protagonist with an armored truck.]]
* In ''Film/BadLieutenantPortOfCallNewOrleans'' a DirtyCop's life starts to spiral out of control as he has to keep committing new crimes in order to deal with the fallout from his old crimes. And since his old crimes were motivated by ''massive'' drug and gambling addictions he hasn't kicked yet, he keeps creating new problems just as soon as it looks like he's solved the old ones.

[[folder:Literature]]
* ''TheHotRock'' (and the movie based on the novel) involves an escalating series of crimes dedicated to stealing a particular diamond.
-->"I've heard of the habitual criminal, of course. But I never dreamed I'd become involved with the habitual CRIME."
* Happens in the ''GauntsGhosts'' novel ''Necropolis''. A trader disobeyed an order to seal off a fuel pipeline he owned since he was making a fortune selling the fuel in the besieged city. Then the pipeline was used by Chaos forces to infiltrate the city and his crime became an act of treason. To get rid of witnesses, he killed the civilian workers he used in his scheme, then he killed his bodyguards who helped him kill the civilians, then his aide (or was planning to, at least), then tried to kill the medics of the titular Ghosts who were investigating the murders. Luckily, he was stopped by Gaunt, but one has to wonder how he was planning to kill the 1500+ pissed-off Imperial Guardsmen that would have torn the city apart looking for him.
* The villains in ''[[ErastFandorin Murder on the Leviathan]]'' first killed ten people in Paris to steal the MacGuffin, then killed a professor onboard the luxury liner Leviathan when he got dangerously close to the truth, then, when the ''investigation'' began to catch on, [[spoiler: decided to just ''sink the ship with all the passengers'']].
* In the HarryTurtledove novel ''Noninterference'', the head of TheFederation's pre-warp civilization Survey organization gets a report from a recent mission that a violation of the titular {{Alien Non-Interference Clause}} had longer-lasting effects than anyone had anticipated. Instead of working on Spin Control (the guy responsible for the inital screwup was cashiered, his mission is used as a case study in What Not To Do, and more to the point he has been dead for over ''fourteen centuries'') she orders the files erased... and goes after the copy downloaded by a xeno-anthropology professor... and tries to shut up the survey team... and tracks down which of the professor's students has a copy....
* In ''Native Son'', Bigger Thomas accidentally suffocates a white girl in her bed. Believing that society would presume a black man like him guilty of having raped and murdered her, he burns her body and writes a ransom note claiming she's been kidnapped. Before Bigger is tracked down and arrested, he rapes and murders a black girlfriend.
* The elderly murderer in ''Dying to Live in Palm Beach'' accidentally took and used her wealthier friend's credit card, then began to do it deliberately until her friend mentioned her kids got her a bookkeeper. She poisons that friend, realizes she likes having money, arranges an overdose for another friend after abusing her card, and shoves a third off a boat when she catches her in the act.
* The murderer in Creator/DorothyLSayers ''Unnatural Death'' would probably have gotten away with the initial murder if they hadn't got paranoid about who [[HeKnowsTooMuch might know too much]] and started offing other people as well. At the end of the story Chief Inspector Parker says of the first murder, "We can't prove it now -- that's why I left it off the charge-sheet."

[[folder: Live Action TV ]]
* ''Series/{{CSI}}'':
** In an episode, a lawyer enjoys a few drinks and hits a pedestrian while driving home. The victim gets trapped in his windshield, but instead of taking him to a hospital or calling the police, the lawyer hides the man in his garage. In the end, it's revealed that [[spoiler:the man jumped in front of his car intentionally to commit suicide, and the lawyer would not have been charged with anything had he not let the guy die in his garage.]]
** Also, the infamous Max from the episode "Loco Motives". It would have worked out much better for him if he had just called the police and told them he accidentally [[spoiler:killed his wife]] instead of what he actually did, which involved [[spoiler:killing his neighbor]] and failing in disposing of [[spoiler:his wife's body.]]
*** Well, technically, none of those things were crimes [[spoiler: 'cept maybe dumping the body and cleaning the crime scene up, and perhaps wasting police time, but thats, by comparison, pretty trivial. Both deaths were accidents]], and its implied they believe him. So he might actually have been let off anyway.
** In another one there was a taxi driver who ran over a pickpocket who refused to pay her fare and ran off with his wallet, [[spoiler: but he only did it because another driver bumped into him on purpose, causing his car to hit her in the head when she tripped. He wouldn't have gone to jail but the other driver convinced him that they both would, so they fled the scene and lied about the whole thing, and tampered with evidence, all of which were crimes. Since he's an immigrant, the first driver is likely to be deported, the very thing he was trying to avoid in the first place.]]
** In the series' pilot episode, a thief returns to the house he'd robbed, presumably to clean up some clue to his identity, and winds up [[spoiler: murdering Holly Gribbs, who is processing the scene]].
** On ''Series/CSINewYork'', Mac spends some time being stalked by a criminal he put away while he was still a rookie, who has some [[YouKnowWhatYouDid unspecified grudge]] against him and his old mentor/first partner. [[spoiler: It turns out that Mac's mentor stole some money the crook was caught with and stashed it at the scene. When he went to pick it up, the crook's girlfriend caught him so he killed her.]]
* In ''Series/TheShield'', the Strike Team starts out making a few deals with some gangs to leave them alone while going after their competitors, and ends up [[spoiler:killing fellow cops]] to cover up their corruption.
* Played with, or perhaps subverted in ''Series/VeronicaMars'' season one, in which the Kanes commit various counts of conspiracy ([[ArtisticLicenseLaw mislabeled in the show as obstruction of justice]]) in order to conceal that [[spoiler:Duncan did not kill]] Lilly. Well, technically, [[spoiler:they ''thought'' he killed her]] and that's why they covered it up. In their defense, they did find him [[spoiler:in a position where he was covered in her blood]].
* ''Series/PrisonBreak'' contains several cases of this. Charles Westmoreland even tells Michael at one point that there's no such thing as an ex-con, which Michael repeats sometime in season two when he realizes how many crimes [[spoiler:and deaths]] he's been directly and indirectly involved in, since he decided to break Lincoln out of prison. Sucre, C-Note and Mahone are also arguable examples of this, as their backstory gradually reveals.
* ''Series/ColdCase''
** An early episode had a guy shoot a man to death, and in attempt to cover it up, he set a fire... which killed at least twenty-two others.
** In another episode the BigBad doesn't even kill the victim -- he just gets rid of the body to protect the idiot that killed her almost by accident. However, as the investigation goes on, he kills another man to keep the secret and when that also fails, he attempts to kill the detective in charge of the investigation.
* Common in ''Series/{{Monk}}'' and ''Series/{{Psych}},'' particularly in Monk where many of the murders are relatively innocent people who were in the wrong-place at the wrong-time. The mystery is finding out why they were murdered in the first place, and it often comes down to the the murder being used to cover up some other crime, which is only discovered through the murder investigation. If that's not the case, someone else is likely to be murdered in an attempt to cover up evidence from the first murder.
** A typical use of this, for example, occurs in "Mr. Monk and the Very Very Old Man," in which a politician accidentally killed an innocent teenager in a drunken hit and run years before the plot happened. Unable to resist confessing somehow, he wrote a letter detailing his guilt and put it in a time capsule, which was supposed to be opened again sooner than expected if the world's oldest man were to live five more years. The politician was eventually forced to kill the man in order to stop the time capsule from being opened, during which he also had to kill a security guard. He goes down for triple homicide in an attempt to cover up his single hit and run.
* A favored trope of ''Series/LawAndOrder'' - especially when the defendant has a rich (or mobbed-up) family to bribe, perjure and intimidate his way to an acquittal.
* In ''Series/PersonOfInterest'' this is usually what gets Finch and Reese involved. The machine is unable to predict impulse crimes but once a crime is committed it can predict that the cover up will involve murders. In the pilot when [[spoiler: {{DirtyCop}}s kill some drug dealers]] the cover up escalates to the attempted murder of a teenage witness and then the attempted murder of the prosecutor looking into the matter. The criminals were willing to escalate things even further since the prosecutor had his young son with him when they tried to kill him and they did not want any witnesses.
* In ''Series/{{Luther}}'', all [[spoiler: DCI Ian Reed]] needed was [[DirtyCop some money]]... but it just [[TragicMistake snowballed]] [[MurderIsTheBestSolution from]] [[NeverOneMurder there]]...
* This is a running theme in ''Series/BreakingBad''. Walt and Jesse want to make and sell meth but to do so they need to make deals with violent and unstable criminals who do not trust them. Sooner or later the other criminals turn on them and Walt and Jesse have to kill them to protect themselves. As they move further up the criminal food chain, they are forced to take more drastic measures and become more ruthless.
** Since it's explicitly stated the series is an attempt to turn Walt from Mr. Chips into Scarface, it's pretty much a given that this trope is going to come into play.

[[folder:Theater]]
* OlderThanSteam: ''Theatre/{{Macbeth}}'' is famous for this one.
[[/folder]]

[[folder: Video Games ]]
* ''PhoenixWrightAceAttorney''
** The bonus case in the first game has this as the motive for Joe Darke in the backstory - a seemingly normal man who accidentally killed a cyclist in a car accident, and then proceeded to go on a killing spree in an attempt to cover up this initial accident.
** The BigBad of ''Trials and Tribulations'' [[spoiler: Dahlia Hawthorne]], who killed their sister to keep her from talking about a fake kidnapping they had staged years ago to steal a jewel from their family. Further details are are a classic example but a big [[labelnote:spoiler]]After that, she (count with us now!) 1) tried to frame her ex-boyfriend who was already convicted by the staged kidnapping; 2) when he was about to be cleared she convinced him to commit suicide so he wouldn't tell the truth to the court; 3) poisoned a lawyer that was tracking her; 4) hid the poison with a young Phoenix, disguising it as a gift of love; 5) she tried to get the poison back from him by killing him, only to end up killing another ex-boyfriend and 6) framing Phoenix for it. After that she was finally convicted and ''executed'', but still 7) returned from the dead years later to try to kill Maya, the sister of the lawyer (Mia) that got Dahlia on prison, to have her revenge. Note that she didn't go for directly killing Mia because Mia was already dead in the interim.[[/labelnote]].

[[folder:Webcomics]]
* ''Webcomic/GirlGenius'': Lampshaded and averted in [[http://www.girlgeniusonline.com/comic.php?date=20031017 this strip]].
** Played reasonably straight with Dr. Merlot [[http://www.girlgeniusonline.com/comic.php?date=20090518 here]]. After several cryptographers on loan from Baron Wulfenbach discovered the true identity of the late Dr. Beetle's assistant Merlot tried to hide his letting the last of the Heterodynes slip through his fingers by burning the notes, whatever secret labs of Dr.Beetle he could find, the hall of records, and ''the cryptographers''. Clearly, his sentence to Castle Heterodyne was [[NeverMyFault all "Miss Clay's" fault]].

[[folder: Western Animation ]]
* Parodied in the first ''{{Futurama}}'' "Tales of Interest" episode, in which a WhatIf machine shows what it would be like if Leela (normally the StraightMan) was more impulsive. She ends up killing The Professor for his inheritance and then slowly working her way through the cast as they catch on, [[spoiler:except for Fry, whom she seduces. Then [[strike: kills]] gets kinky.]]
