-->-- '''Agent Fox Mulder''' (having read that ''Fox can't guard the chicken coop''), ''Series/TheXFiles'', "Young at Heart"

The detectives are on the heels of [[{{Idiosyncrazy}} a very unbalanced criminal]] who has left them a trail of clues to follow -- usually a test of their intellect, or their investigatory skills, as though the criminal wants to see if the detectives are worthy of catching him. Not only do the detectives oblige the nutter and follow his breadcrumb trail, they tend to give up all conventional routes of investigation. Usually they are the minutest step behind their quarry right until the end. Sometimes the criminal wishes to distract or trap the detectives, sometimes they want them to uncover some other truth along the way, but usually they're just being a real smartass. Sometimes the clues are hidden in the SerialKiller's CallingCard or in its gruesome [[FingerInTheMail souvenirs]]. There is often a BreakingSpeech (or TheReasonYouSuckSpeech) and a KirkSummation (or WorldOfCardboardSpeech) exchange between TheProtagonist and antagonist some time before the climax.

These people often enjoy wordplay. Anagrams abound, as well as sentences with a carefully designed second meaning, and proper nouns which are conveniently also real words ("wait a minute, does he mean ''Jim'' Trashcompacter?").

!!Examples

[[foldercontrol]]

[[folder: Anime and Manga ]]
* ''DetectiveConan'':
** A number of episodes of (especially the longer TV specials) involve some criminal leaving a trail of clues—either because they secretly want to be caught and stopped, or because they're just AxCrazy. For whatever reason, many of these seem to involve bombs.
** One TV special had Conan and Heiji running all over a baseball stadium to try to catch a would-be stadium bomber who sent them clues via abandoned mobile phones with a specific time limit to find the next one.
** "Trembling Metropolitan Police Headquarters: 12 Million Hostages" involved a mad bomber who sent a clue to his next target to the timer screen of his current bomb…seconds before its detonation.
** A long manga story set in London had a bomber leaving a trail of Sherlock-Holmes-themed clues all over London for Conan to chase down in order to stop his next bombing.
* Subverted in ''Manga/DeathNote:'' the master detective L expects Kira to be leaving messages -- but Kira is just as smart as he is, so only leaves red herrings to throw L off the scent, or meaningless clues to waste his time. And the main purpose of leaving the messages was in fact for Kira to [[HowDoIShotWeb test the limits of the Death Note's power]]. Leaving false clues for L was just a side benefit.
* In ''Anime/CodeGeass'', Lelouch invokes this in the Brittanian Army by asking Jeremiah Gottwald if he really wants people to find out about "Orange". He then Geasses Jeremiah into letting him escape, making it look like this "Orange" was a threat that Jeremiah caved to. Truth is that "Orange" is meaningless, and Jeremiah is innocent of any crimes or conspiracy by Brittanian law, but this still disgraces him and gets him investigated.
[[/folder]]

[[folder: Comic Books ]]
* In all incarnations of ''Franchise/{{Batman}}'', this is ComicBook/TheRiddler's modus operandi; other Batman villains, like The Joker, have also done it.
** Lampshaded during the VillainTeamUp in ''Film/BatmanTheMovie'', where the Riddler's colleagues eventually grow tired of him compromising their plans by leaving clues that they know Bats will inevitably solve. They try to stop him from doing so, but he fervently declares that he just can't resist and proceeds to leave more clues that eventually lead to their defeat.
** Interestingly, an early Batman story showed that the Riddler's insanity is such that he is physically incapable of committing a crime unless he leaves a clue. (His father used to beat him when he lied... so once dear old Dad was out of the way and only the consequential neuroses were left, he learned to tell the truth in extremely sneaky ways to get around them.)
** One [[ComicBook/BatmanAdventures comic]] set in TheDCAU had Batman ''fail'' to decypher the Riddler's clues; he stumbled upon the crime because he was following three other crooks who had the same target. When the Riddler realizes this, he doesn't care that he's going to jail because as far as he's concerned, he ''won''.
** Subverted by another ''Batman'' villain, the Cluemaster, a bargain-bin Riddler type with a similar ''modus operandi''. The Cluemaster was caught thanks to his own clues and went to prison, an experience which cured him - of leaving clues. Once free, he resumed his criminal activities without bothering to leave clues any more. As Robin says, "[[NiceJobBreakingItHero Gee, thanks Arkham!]]"
*** Unfortunately for him, his daughter, Stephanie Brown, was angry at him for trying this while claiming to be reformed, and became The Spoiler, leaving clues to her father's crimes for Batman. [[ArtifactTitle So that's what the hell her name means.]]
** In his first re-appearance, the Cluemaster had hired some goons who, knowing their boss's old M.O., left clues behind anyway. And being stupid goons, the clues were really obvious, too.
* Issue #6 of ''Comicbook/UntoldTalesOfSpiderMan'' had Spidey and the Human Torch working together to stop The Wizard, who left logic-based puzzles as clues to his next caper. The crime spree was The Wizard's attempt to prove that he was smarter than the Torch, but [[GeniusBruiser Spider]]-[[TeenGenius Man]] solved them all fairly easily.
* ''Bedlam'' is about Fillmore Press, who was once the mass-murdering psychopath Madder Red. Reformed and largely stable after a stint in a mental hospital, he hears about a string of murders that have the police baffled and realizes that he knows the killer's next move and why he's doing it in the first place. He calls in a tip to the police on a burner phone, profiling the killer, describing his M.O., and doing everything he can to help the investigation along. Sadly, his analysis is so in-depth that the cops think ''he'''s the killer, with one of them even comparing the call to Son of Sam's letters.
* ''ComicBook/FromHell'', being based on a [[JackTheRipper real-life example of this behavior]], includes the trope.
[[/folder]]

[[folder: Film ]]
* ''Film/{{Se7en}}'', [[spoiler:although that was all part of a ThanatosGambit]].
* In the movie ''Film/IRobot'', the [[spoiler:"murder" ''victim'']] does this, the initial clue being [[spoiler:[[ThanatosGambit his own "murder"]]]], ostensibly to reveal his secret to the hero without tipping off a [[spoiler:ThreeLawsCompliant AI with SinisterSurveillance]] in time to prevent a [[spoiler:ZerothLawRebellion]]. (Yeah, the ''movie'' did something clever and subversive. )
* The movie ''Film/InTheLineOfFire''.
* Averted in ''Film/TheWatcher''. Oh sure, the SerialKiller would like to get the detective to play a game with him, but the detective doesn't care [[spoiler: in part because ItsPersonal]]
* V was this in ''Film/VForVendetta'' to the inspectors (Nose, not Finger). He actually used the term, but in a more insulting/literal reference to Creedy.
* ''Film/TheAbominableDrPhibes'' accidentally dropped a medallion with some Hebrew lettering at the scene of one of his crimes, which tipped the police off to the Old Testament [[ThemeSerialKiller theme of his serial killing]].
* In ''BeverlyHillsCopII'', this is the BigBad's apparent modus operandi, by leaving so-called "alphabet clues" at the scene of each of his daring crimes. It turns out to be a {{subversion}}, as the clues are designed to distract the {{By The Book Cop}}s' attention and set up a RedHerring scapegoat while the real mastermind escapes.
* Jigsaw does this in ''{{Saw}} 2'', having abducted a Detective Matthews' son and left him, and numerous other victims-including Amanda, a survivor of his games- in a house filled with death traps, and is recording the whole thing, which becomes useful when the detective and a SWAT team show up to arrest him. Jigsaw says the son will be returned alive and safe if Matthews just has a conversation with him, but the house is also filling with nerve gas that will kill everyone inside in two hours. [[spoiler: The son is locked in a safe in Jigsaw's room, the video is not live and everyone in it is already dead apart from Amanda, and when Matthews shows up thinking he'll save his son Amanda reveals that she was Jigsaw's apprentice, and the whole thing was a revenge scheme of hers because Matthew's once framed her for a crime, ruining her life, and it ends with Amanda leaving him to die locked in the room from the first film]].
* ''Film/TheBoneCollector'' (originally a book) has a killer who leaves clues at each murder scene relating to his next crime. Upon further investigation, it turns out that he has been killing and leaving clues for ages but no one was smart enough to notice.
* Subverted in ''Film/DieHardWithAVengeance'' with "Simon" playing a Simon-Says type game with the main character through the first half of the movie in order to prevent a bomb from being detonated. Subverted in that [[spoiler: it's shown to simply be a way to get [=McClane=] (and the entire NYPD) out of the way while Simon pulls off a heist of the federal reserve.]]
* In ''Film/HellraiserInferno'', the Engineer serial killer is constantly leaving messages to Detective Joseph Thorne as he kills the people around him and leaves behind the dissected fingers of his child victim. [[spoiler:This is because Joseph is actually both the cop and the murderer. "Hunt the Engineer and the Engineer hunts you".]]
* The killer in ''Film/{{Anamorph}}'' hides an anamorph in each crime scene that depicts the next one. He also leaves messages for Aubrey.
[[/folder]]

[[folder: Literature ]]
* The JamesPatterson novel and movie ''Along Came a Spider''.
* OlderThanTelevision: Literature/SherlockHolmes himself had to deal with his share of these villains. This seems to be particularly common for movie and video game versions of Holmes, and less so in the Canon. In particular, he's been sent on scavenger hunts through famous sites in London by thieves ''twice,'' at least -- in the Creator/{{Infocom}} text adventure ''The Riddle of the Crown Jewels,'' and in the more recent ''Sherlock Holmes: Nemesis''. Ironically, Moriarty is the villain and riddler of the former, not the latter.
* Creator/AgathaChristie's Hercule Poirot came up against a CriminalMindGames villain [[spoiler:or so it seemed]] in ''The ABC Murders'', where the killer sent him mocking letters before each of the murders.
* Double-subverted in John Buchan's RichardHannay novel ''The Three Hostages''. The villain leaves a riddle for the police, in the form of a six-line poem. Subversion: It's deliberately uncrackable, and therefore ''should'' act only as a distraction. Double-subversion: But, possibly subconsciously, he laces the riddle with subtle clues, which the heroes crack thanks to a number of [[ContrivedCoincidence remarkably fortuitous encounters and observations]].
* In ''Blood Work'', the "Code Killer" leaves the number sequence "903 472 568" at his crime scenes as a taunting hint. The solution? [[spoiler: All the decimal digits are represented except 1, and his real name is Noone ("No one").]]
* Creator/GKChesterton's very first ''Literature/FatherBrown'' mystery, ''The Blue Cross'' subverted this in two ways: first because the clues themselves were meaningless, and second that it wasn't the criminal leaving them.
* ''Literature/EightySeventhPrecinct'': This is the M.O. of recurring villain the Deaf Man in Creator/EdMcBain's novels. There is a slight aversion in that while the Deaf Man sends taunting clues to the police, they seldom fully decipher them and are more likely to stop his crimes by accident than design.
* Used by Melisande in ''[[Literature/KushielsLegacy Kushiel's Chosen]]''. She thinks of her attempt to gain control of Terre d'Ange as a game and Phedre as her WorthyOpponent, and so sends Phedre a hint to start her search.
* Subverted in Creator/JorgeLuisBorges' ''Death and the Compass''. Lonnrot thinks he's oh-so-clever for figuring out there'll be four cabalistic assassinations, not just three... [[spoiler: It turns out the first one was an accident, and the second and third were rigged in order to get Lonnrot - who has a very romanticized view of detective work - to come to that conclusion, and show up in a location where his nemesis Red Scharlach can off him.]]
* Played with in ''Literature/RedDragon'', where the police intercept a fan letter the SerialKiller sent to his idol, Hannibal Lecter. Lecter begins corresponding with him in the sensationalist newspaper ''The Tattler'' with a cryptic message, and as the FBI aren't able to decipher it in time they decided to let go ahead as it's their only means of contacting him, and when they finally deciphered it they could take Lecter's place. Unfortunately, it wasn't the Dragon they were playing mind games with - Lecter's message [[spoiler: told the Dragon the hero and his family's home address, and said he should kill them all.]]
* ''LightNovel/AnotherNote'': The entire book is about trying to solve a very, very, difficult one of these. The killer, [[AsLongAsItSoundsForeign Beyond Birthday]], left several clues leading from one murder to the next. None of the investigating officers could even start to decipher B's clues. Only Naomi Misora -- under L's guidance -- and an "unprivate" detective named Ryuzaki could help. The clues lead Naomi Misora ''in person'' to find each and every one of these clues to make sure the effort didn't go to waste. [[spoiler: Ryuzaki ends up doing most of the work. He turns out to be the killer who placed the clues there in the first place.]]
* ''Literature/TheBoneCollector'': (described under Film).
[[/folder]]

[[folder: Live Action TV ]]
* Subverted in ''HomicideLifeOnTheStreet'' in the episode "Sniper". A serial killer draws a hangman game in chalk at the scene of each crime, with another letter filled in each time. The detectives hope that if they can guess the word, they can solve the crime. [[spoiler: It turns out that the word is "eromitlab," a nonsense word -- Baltimore backwards. The killer is simply crazy. There's nothing more to it than that.]]
* ''Series/LawAndOrderSpecialVictimsUnit'': though the police didn't give up on traditional methods entirely. In fact, by ''using'' traditional methods, they're able to catch the perp ''before'' he can complete his intended killings, and even manage to save a victim without stooping to his level.
* ''{{Series/CSI}}'': Occurs with vastly more complex clues than usual.
** For starters, it happened with the following: Paul Millander (prop artist who enjoyed taunting Grissom), the Blue Paint Killer (likewise), Nicky's kidnapper at the end of Season 5 (who did it to prove a point), and the Miniature Killer (who only left clues because of an involuntary urge due to psychosis). Arguably, the Strip Strangler was amused at the police and FBI's feeble attempts at capture, but was meticulously neat and planted fake evidence rather than ''leave'' any.
* ''NUMB3RS'': Usually the clues require advanced mathematics to unravel, since the show's Aesop is that Maths is useful and mathematicians are like superheroes -- with maths. "The Janus List" [[GambitRoulette took this to ridiculous extremes]]. Supposedly, the whole point of the exercise was to give the FBI a list of double agents, but the character who had the list made it all but impossible for the FBI to find it. [[spoiler:To be fair, this also hid the list from double (triple?) agent Colby Granger -- but routes much more direct were available.]]
* ''Series/{{Charmed}}'': A group of demons perpetrates a series of attacks using an Alice in Wonderland theme. The justification is that the Charmed sisters have recently faked their own death, and the demons have a theory that they are still alive and won't be able to resist investigating murders if there's a fairytale theme to give it that extra captivating interest.
* In the season 3 finale of ''{{Psych}}'' Shawn faces the Yin-Yang Killer, who only rarely resurfaces to screw with star cops -- by kidnapping a victim and leaving stopwatches and clues, with the victim dying when the star cop fails to solve the clues in time. When the Yin-Yang killer targets Shawn, Shawn gets caught up in the killer's clues, and [[spoiler: then he realizes that is what the killer wants and pretends to give up.]] Eventually the killer is revealed to be [[spoiler: a very crazy looking Ally Sheedy.]]
** One of the rare straight uses of this trope that manages to be funny: Detective Lassiter thinks the Yin-Yang Killer is testing him, specifically. [[WrongGenreSavvy He is...wrong]].
** They do it all again the next season with Mr. Yang's partner, Mr. Yin.
* ''Series/MacGyver'' had an escaped criminal foe who went as far as to call him with math equations that would yield a clue when solved.
* Variant: the ''Series/{{Ghostwriter}}'' episode "A Crime of Two Cities." A cross-Atlantic trio of kidnappers is led by a nutty mastermind who insists that they commit their crimes (and communicate with each other) through trick sentences and anagrams, all of which mock their intended victim. Unlike the usual trope, the leader isn't testing the heroes. She's doing it because she's arrogant, and wants to show off how the heroes are incapable of figuring out her clever clues.
* ''Series/{{Dexter}}''.
** Dexter himself does this to mislead the agents investigating his own murders. In a twist, his attempt to mislead actually helps the FBI agent to narrow down the investigation.
** Subverted when The Ice Truck Killer sends clues to the police, but they're really meant only for Dexter.
* Often done in ''ThePretender'' by Jarod to the Centre operatives chasing him both to mock them and to leave clues that their superiors were up to shenanigans behind their backs. Done more often in the first couple of seasons... later on, Jarod simply calls them to tip them off about their employer's latest wacky hijinx.
* ''Series/CriminalMinds'' has done this twice. In "The Fisher King", an unsub mostly just wanted to send them on a quest. Some of the team worked on it like a normal case, some of the team followed the breadcrumbs. The trail of breadcrumbs solved the case, and not following the rules nearly got one of the BAU killed. In "Masterpiece" [[spoiler: the clues led to a trap. Luckily, they figured that part out in time.]]
** The unsub in "Unfinished Business" who seems to be partly based on the Zodiac Killer and on the BTK killer Dennis Rader, who also left letters. The only Zodiac thing was that Rader's letters just taunted the police; he never left cryptic clues in them, though he would announce that he had chosen his next victim.
* ''{{Bones}}'' did this with serial killer [[spoiler: Howard Epps.]]
* One episode of ''Series/DueSouth'' had this. [[spoiler: Although Ray subverted it, when he admitted to Fraser that he was never good at solving puzzles, knowing that the villain had a mike in the car, intending to lull him into a false sense of security.]]
* In ''BurnNotice'', Gilroy leaves clues about his identity to Michael this way. To quote TelevisionWithoutPity, "either someone is setting up Mason Gilroy, or Mason Gilroy thinks he's the fucking Riddler."
* ''Series/{{Sherlock}}'' does this in the first season finale, "The Great Game." In a somewhat unique instance, the perpetrator is using unsolved cases as the bait for Sherlock, forcing him to dig up the truth so that his victims won't be killed.
* Fox Mulder of ''Series/TheXFiles'' tends to get into these with reasonably human MonstersOfTheWeek, such as John Irvin Barnett from "Young at Heart", Robert Modell a.k.a. "Pusher", [[spoiler:Mulder's ex-mentor]] from "Grotesque", and [[spoiler:Modell's even eviler twin]] from "Kitsunegari".
* The ''Series/MurdochMysteries'' episode "Murdoch in Toyland", in which Murdoch is left a series of talking dolls designed to give him just enough clues to reach the next one, and also to make him overthink things and miss more blatant clues. Murdoch's nemesis escapes, and returns to torment him some more [[spoiler:by framing his love Dr. Ogden as a murderer. He also claims human love fascinates him and that he wants to see whether he could give up his life for hers.]]
* In the ''Series/StarskyAndHutch'' episode "Bloodbath", Starsky is snatched by a cult whose psychotic leader is in prison; he gives Hutch just enough cryptic clues to track Starsky down in the nick of time.
* ''Series/{{Elementary}}'' has the mysterious 'M' leaving rambling notes for the police, using letters cut out from newspapers of course. As Sherlock correctly guesses this is really a ruse to follow the police into thinking he's something he's not.
[[/folder]]

[[folder: Music]]
* The subject of Music/AliceCooper's ConceptAlbum "Along Came a Spider".
[[/folder]]

[[folder:Puppet shows]]
* ''Series/CaptainScarletAndTheMysterons'': The Mysterons do this all the time. Somehow, despite tipping their hand every single time, they actually ''win'' in a few episodes, starting with the second. This is justified because the Mysterons have declared a "war of nerves", seeking to make the humans prone to self-destructive paranoia even if their specific plan of the episode fails... Or they're just doing this [[ItAmusedMe for their own amusement]] and the human race are unwilling contestants in some sick hybrid of ''Series/{{Survivor}}'' and ''Series/TheCrystalMaze''.
[[/folder]]

[[folder:Tabletop Games]]
* In ''TabletopGame/{{Exalted}}'', [[DarkMessiah Infernal Exalts]] are able to atone for their actions that displease their demonic/titanic masters by committing [[CardCarryingVillain Acts of (Card-Carrying) Villainy]]. An example is "Best Enemy Recognition," in which the Infernal chooses a rival Exalt of roughly their same power level to be their ArchEnemy, and continuously attempts to draw the Exalt so designated into their life by such methods as sending them clues alerting them to their evil deeds.
[[/folder]]

[[folder: Video Games ]]
* The final case of the [=DS=] game ''Unsolved Crimes'' is one big series of these.
* The game ''{{Ripper}}'', based on Jack the Ripper. But [[InSpace in the future]]!
* ''CarmenSandiego'': Carmen is possibly only second to the Riddler in being known for this. She leaves the clues as a friendly challenge of wits against the FriendlyEnemy / WorthyOpponent detectives.
* ''VideoGame/{{Persona 4}}'' has this with the Phantom Thief, who leaves clues for Naoto after stealing her items. This is a subversion in that the Phantom Thief turned out to be [[spoiler: Yakushiji, the family secretary and he didn't steal the items, they were simply handed to him by Naoto's grandfather, who set the whole thing up as an act so Naoto would stop worrying about the family name and remember that she solved cases because it was something she loved doing.]]
* In the Homicide chapter of ''LANoire'', [[SerialKiller The Black Dahlia]] deliberately leaves a series of clues that Cole eventually uses to track him down. Specifically, [[spoiler:He sends the LAPD a taunting letter that contains a passage of Shelley poetry; the passage contains allusions to an LA landmark. When Cole visits the landmark, he finds a piece of evidence which links the Dahlia to a recent murder and another passage of Shelley which alludes to a different landmark. This continues until the final passage leads Cole to the Dahlia's hideout.]]
[[/folder]]

[[folder: Webcomics ]]
* Subverted in ''IrregularWebcomic'': The heroes follow the hints, [[http://www.irregularwebcomic.net/comic.php?current=1345 but get the wrong message.]]
** Doubly subverted in that the place they're supposed to be going to is [[http://www.irregularwebcomic.net/comic.php?current=1404 right next door]].
[[/folder]]

[[folder: Western Animation]]
* ''TheSimpsons''
** Chief Wiggum was the "Mutton-Chop Murderer", who wanted to create a crime even Lisa Simpson couldn't solve. Played as a parody, natch.
** Subversion; Bart hides Lisa's report and challenges her with a series of riddles:
-->'''Bart:''' To find it, you'll have to decipher a series of clues, each more fiendish than...
-->'''Lisa:''' Found it!
-->'''Bart:''' Doh!
* Spoofed in the ''WesternAnimation/SouthPark'' episode "Chickenlover": the titular animal molester always left a message at the scene of the crime. The clues turn out to be really, really obvious... ''but Officer Barbrady is illiterate,'' and thus, he can't read the messages. After forcing himself to painstakingly learn to read through children's books, he eventually manages to find and arrest the culprit... who turns out to be a bookmobile driver who was trying to encourage Officer Barbrady to confront his illiteracy, even though there was no way he could have known about it before he molested the first chicken.
** Barbrady then celebrates his new found literacy by beginning to read books...starting with ''Literature/AtlasShrugged'', which he regarded as such utter garbage that he decided he would never read again, making the bookmobile drivers whole plan null and void.
* ''BromwellHigh'': One of the girls hides some illegal sweets people are looking for and composes a rhyme telling where they are.
--> If it is the sweets you seek, into the cloakroom you must sneak, and find where I keep my books, and hang my coat and bag on hooks. Behind the metal doors is stowed the sweets what make your head explode.
* The animated version of ''Where On Earth Is CarmenSandiego'' has this in every episode as a ShoutOut to AlphabetSoupCans. [[{{Irony}} Ironically at least one episode has the lead characters being puzzled when clues seem too obvious or follow an unusual train of logic.]]
* Subverted on ''MonkeyDust'' when a serial killer becomes entangled in a furious game of cat and mouse with a police detective. The thrill of the chase is blown when the serial killer accidentally falls asleep in his car at the crime scene after killing a man: blood stained and with weapon in hand. Disappointed that it ended with such an anticlimax, the police detective decides to let the killer go. Only to be then killed by him.
* Lampshaded in ''TheReplacements''
--> '''Master Pho''': I would have gotten away with it if it hadn't been for that meddling kid.
--> '''Todd''': Actually, you would have gotten away with it if you hadn't left us all those clues.
[[/folder]]

[[folder: Real Life ]]
* The Zodiac Killer; a serial killer who taunted California policemen with postcards and letters written in secret code. According to the letters he sent to the press, he killed people in order to have slaves in the afterlife. Ergo also his [[NoCelebritiesWereHarmed obvious stand-in]] Scorpio from ''DirtyHarry''. A number of investigators and researchers consider many, if not all, of his "clues", including his codes, to be purely [[RedHerring red herrings]]. He was never caught.
* JackTheRipper wrote letters to the police and newspapers, taunting them. The "From Hell" letter is the most infamous, as it was delivered [[FingerInTheMail along with part of one of the victims' kidneys]].
* Others who sent letters (some of them more coherent than others) include Son of Sam, BTK, and the Axeman of New Orleans. Usually, the capture had little to do with the any attempted mind games: Son of Sam was captured when a witness saw him loitering suspiciously near his illegally parked car around the time of the shootings then confessed quickly. BTK was caught after a floppy disk he sent was traced to a computer registered by a local church (after being assured by investigators in a previous comunication that oh yeah, they totally wouldn't be able to trace a floppy disk in any way).
* Fugitive Scott Burnside (featured on Investigate Discovery's ''I (Almost) Got Away With It'') sent a recorded message to investigators shortly before he fled the country, taunting them with an offer of testifying against the co-conspirators of the quadruple murder he was linked to.
