Fiery Coverup

"Fire! To destroy all you've done!"

—Fire, The Crazy World of Arthur Brown

Fiery Coverup is the act of blowing up or burning down the evidence implicating you in some crime. Very popular among evil corporations and governments who go as far as torching entire city parts to cover up something particularly nasty. Often takes place when the heroes are in the middle of discovering said evidence.

Very much Truth in Television. Part of firefighter training is to be on the lookout for signs that fires might have been started to conceal another crime, such as noting if a window was broken before they put an axe through it to get into the building. Also known to happen in cases of insurance fraud.

A Sub-Trope of Revealing Coverup. Also compare its sister tropes Gas Leak Coverup and Kill It with Fire.

Examples of Fiery Coverup include:

Anime and Manga

Aoyama Pharmaceutical in Mnemosyne demolishes Sayara Yamanobe's secret lab soon after it is compromised in the first episode.
Common in Detective Conan when the Men-In-Black are involved.
Rurouni Kenshin - this was attempted on Shishio Makoto. It didn't kill him, but it did leave him covered head-to-toe with third degree burns.
Triage X - The method the protagonists use to hide the evidence of their vigilante actions. Frequently involves destroying the entire (abandoned) city block.
In Death Note, Light has an elaborate setup to hide the Death Note. It's in a drawer, under a false bottom, with a circuit underneath the false bottom, around the Death Note. There is a rubber pad that keeps the circuit from being completed when the false bottom is down; the only way to take it out is to slide the ink barrel of a pen through a small hole on the underside of the drawer to block the circuit and push the false bottom up. If the circuit is completed, the Death Note will be ignited. This way, even if they suspect that he's Kira, even if they know about the Death Note, even if they realize that there's a false bottom on the drawer, the Death Note will be reduced to ash and they will have no proof.
- Later he uses fiery deaths to dispose of his girlfriend and Mello.

Comic Books

Fan Works

In Aeon Entelechy Evangelion the OIS forensic team tries to find any evidence on the group who compromised the airport security on the day Shinji arrived. Problem: They are doing in the aftermath of battle, where one side, the NEG Army, was desperate enough to lob relatively small tactical nuclear warheads at the other side, the Third Harbinger Asherah, who casually violates spacetime and reality while pwning the humans with ease. Suffice to say, there is not much to dig.

Film

Resident Evil 2. The Umbrella Corporation uses a 5 kiloton tactical nuclear warhead on Raccoon City to destroy the zombie infestation, as well as all evidence that they were responsible for it. They plan to claim that the explosion was a meltdown at a nuclear power plant, ignoring the fact that nuclear plants can't explode like a nuclear bomb.
At the end of Alien vs. Predator: Requiem, the government nukes the entire town to cover it up.
In Return of the Living Dead, the last survivors call the military for help and are assured they will take necessary steps... not to save them though. Apparently standard operating procedure for this kind of event is to napalm the affected area. This fails brilliantly as the fire just kicks more of the zombifying chemical into the air, to then fall as acid rain on an even larger area.
In Outbreak, the military threatens to bomb the town in order to contain the virus.
In The Hunt for Red October, Captain Ramios is trying to cover up disobeying his orders. The evidence is the orders in question.
Sherlock Holmes. Sherlock and Watson are looking through the dwarf's laboratory when Blackwood's mooks saunter in carrying arson equipment, leading to a fight.
- Taken Up to Eleven in the sequel, where Moriarty succeeds not only in destroying the room where the crime took place, but killing everyone who was in the room at the time by blowing them up. But Holmes manages to figure out that it was a cover to hide the shooting of the owner of a weapons factory (the owner himself was shot in the head by a sniper seconds before the explosion happened).
  - Which begs the question, why even bother to shoot the guy if everyone else in the room was killed by the bomb?

This has been done a few times in NCIS. Once, to cover up the death of Jenny Shepard, who died in California, by making it look like an unfortunate accident at home so that the newsmedia doesn't learn about the true cause of death. Another time, it is revealed that members of Moussad who are compromised will call in special teams that cover up evidence of the operative in question by staging a fire. In a third instance, a hostage is placed on a pressure plate that threatens to blow up everyone and everything in the room, including computer banks that contain considerable evidence if the hostage is removed (the hostage is safely removed in a manner referencing one of the Indiana Jones flicks and returned to safety, but the aforementioned evidence went up in smoke).
In Nikita, Division uses this method to remove themselves from the scene of a crashed drug smuggling plane.
- Division also uses a large fire to cover up their involvement in the murder of the Udinov family.
- and Nikita herself uses this method in the finale, to destroy her safehouse.

In the season two finale, she discovers that a) Dexter is the Bay Harbor Butcher and b) all the evidence to incriminate him is in the cabin. To help him, she blows it to Kingdom Come. It actually does help him, in far more ways than she initially realizes.
- In the Korean Series Twinkle Twinkle Granny's secret stash of loan shark contracts, money, and object d'art are detroyed by fire at her hidden warehouse.
An episode of "The Mystery Files of Shelby Woo" revolved around that episode's culprit burning down houses to hide the fact that they were illegally harboring endangered animals inside the houses.
Monk has this happen in one episode. "Mr. Monk Can't See a Thing" has a murder where the victim is strangled and then her house is set on fire. Then the perpetrator forgets his keys, and acquires a firefighter's coat and helmet by force (bludgeoning and killing a firefighter with the bottom of a shovel and then blinding Monk with a bucket of cleaning acid) to get them back.
Played for laughs in Arrested Development. When Michael discovers that a storage unit his father tried to keep him from finding out about has burned down, it doesn't take him long to connect it to the recently released arsonist who's been set up with a job at the banana stand (which he readily admits to).

Web Comics

Subverted in Girl Genius, when someone wants to try this but a more Genre Savvy conspirator points out just how suspicious that convenient fire would be. It can be found here and here.
- Merlot tries this as well, to destroy information about Agatha. Since one of the things he had to burn to destroy this knowledge was the people who had read the files, it is not surprising he got sent to Castle Heterodyne anyway.

Real Life

There may have actually been 150 dead. Very grisly and probably NSFW photo here.
