How to Commit the Perfect MurderModern forensic science should make it impossible to commit murder and get away with it. But how easy would it be to outfox the detectives? With the help of top forensic scientists, and real-life murder investigations, we explore whether it's possible to commit a perfect murder.

The body is the most important piece of evidence in any murder. Pathologist Dr Richard Shepherd reveals the crucial clues that give away the secrets of a suspicious death. Dr Lee Goff can work out a time of death from just a few maggots on a corpse. To really understand the way a human decomposes he relies on experiments - and dead pigs make ideal human models.

And what is the perfect murder weapon? Probably Agatha Christie's favourite - poison. It leaves no marks on the body, and the victim may not even realise what has happened until it's too late. But there still might not be a perfect murder. The world's most notorious poisoner - Harold Shipman - was eventually caught. (Excerpt from

Okay so you could method 1: use potassium chloride and put the needle under their tongue, it will look like they died of a heart attack, don't leave DNA you will get caught, if they bring you in dont panic but act calm and look really sad so you look innocent because you were close to them. Method 2: find a poisonous animal, but dont touch it capture it somehow and then when you are alone with the person put it one them but dont do it around the cameras after the person dies of poison take the body out but dont leave DNA on the body you will get caught use rubber gloves and be shure that no one knew you were with them... or... once the poison kicks in call an ambulance and start crying, explain to them that an animal jumped on them but the ambulance could not save them cuz the poison already did their job by the time they come then you will be off the hook because you were the one that called the ambulance..
Dont know if it will work cuz i didn't do any research and wrote this in 2 minutes but if you research you will know i think

Tbh, the best way to do it is to act as if it were an act of self defence. Make sure to leave bruises on your body or even scars to make it seem like your target was the one who started it. Also make sure its in a place without cameras, or you'll get caught within an instant. If you say it was an act of self-defence with a terrified face, you should be in the clear. The most innocent are those who were in the middle of it, am I right?

I’m not sure if this is the perfect murder but if you inject snake venom into the vain where the injection marks won’t be shown . Don’t leave any dna around or bruising on the body. This way it would look like the victim died from being snake bitten. The human would slowly die 45 mins later after being infected. BTW try to have kill your victim outdoors or place them in outside after the injection

If you really want and need to kill someone, Method 1: an injection of potassium chloride under the tongue will show up as a heart attack on an autopsy. Method 2: If you slit the victims wrists and place the knife in their hand, it'll be ruled as a suicide Method 3: If you shoot the victim in the head, and leave the gun in their hand this will also be ruled as a suicide Method 4: If you hang them and knock over a chair under their lifeless body hanging, it'll again be ruled as a suicide. If your going to be killing someone WEAR RUBBER GLOVES, if police go looking for fingerprints they wont find any because you have rubber gloves on covering your bare hands. If you get brought in for questioning, don't panic because if you panic you'll look suspicious, if you look suspicious you'll get caught, if you get caught its game over. However if you do pull it off you'll live your life free of that person. If there is any murder weapon, blood, stained clothes, etc. DO NOT USE BLEACH TO CLEAN UP, use hydrogen peroxide and dish soap. Once finished, walk around like you have zero clue what happened. One last thing, Make sure your murder is flawless and clean<3

Took me like 2 seconds so not so perfect
So first you need to get hold of the victim while they are sleeping so then there's less chance of marks on the body due to fighting and then drug them with anesthesia.Get the victim out of the house and try not to touch a single thing (if the police find ur dna on anything just say you were really close freinds so u always went there) and then take them to a forest near drug them more with some simple pills to make it seem like an overdose,you need to now hang them on a tree after you're done strip them and dump the clothes and ur clothes in a far away river after you're all done sleep on the streets the next morning go to the public swim baths and shower there to get all evidence of.Complete act like ur normal self

an injection of potassium chloride looks like a heart attack on the autopsy. if you don't want to leave an injection mark on the arm or neck do it under the tongue when they are asleep because they won't realize and because no one will be able to realize it was an injection because they can't find the needle mark

you have to bury it very deep about 20 feet cover it up like 16 feet then bury a dead animal so that the animal it 4 feet deep and when the dog smells for a body they will just see the dead animal

Complete annihilation of the body. If there is no body then there is no murder.

The police can't catch you when you kill and hide a dead body. Since there will be no corpse, it will not be known as murder. Then the only way for the police to survive is to close the case saying they are missing. And once he is proven missing by the police, no one will dare to suspect you. The only thing you have to do after hiding the corpse is to make a beautiful story and tell it to the police. And yes, since you committed the murder, you have to buy some false witnesses.
However, if you tell the whole story to anyone, then you are likely to be caught...
(It’s my personal thinking I might be wrong.)

The perfect murder would not require to hide or distort the body. You would want the death to look like somebody just died of natural causes or a sudden heart attack. Something like potassium OD to cause a heart attack.

Considering today's technology there is no perfect murder; only murders that have not been solved...yet. One thing for sure, if two people know a secret it is not a secret. So, loners have the advanage.

First, all of us sucks, but thems da facts. Murder is helping someone die earlier than they were suppose to. It is not something that happens to only the murder victim since we all die. It is sad and most of us can't really understand that we WILL die...we think maybe we will be lucky and it won't happen to us.
Now, to help someone go where they are going to go anyway is not as horrible when you think in terms of reality. But to assist the early death of someone at random is terrible. On the flipside, what if the person you help die early just got done raping a 5 year old? AND...likely that person will rinse and repeat? What about a person who posts videos of him or herself beating, strangling, burning dogs, cats, and other animals to death? AND that person will likely rinse and repeat?
You get my point now?
Since you now understand that the abuser exemplified above WILL LIKELY die upon reaching 75, 80, 85 of natural causes, is it really that wrong to help them leave the planet a decade or more earlier?
It actually is the RIGHT thing to do BECAUSE innocent children and animals would not be future victims if THE ABUSER happened to die early.
To agree, you definitely have to be intelligent and open minded and think MORE about the suffering of the victims rather than the untimely death of the abuser.

I think if you murder someone and make it look like it was a sudden death then it will be a pretty good one. In the dead of the night after committing the murder go to the next room and sleep. In the morning pretend to discover the death and call up relatives saying he died of a heart attack..have a funeral and forget all about it.

A perfect way to dispose of the body and your evedence is grind it all up your cloths that you had on at the time and the human you killed and feed it all to pigs. Pigs will eat anything or you can kidnap the person preferably a drifter or homeless tie the hands behind there back and there legs together than let dogs attack or a way I once thought of comiting the perfect murder : break into the house as stated before with a hair net I would use a panty hose holds it all in and tight on your head and hides distinct marks on face than get you shoes that you never owed or worn in your life where them 2 sizes smaller or biger to eliminate your shoe size to shoe print found at scene of crime and cloths you don't ever wear and you can dispose of easily than slip some muscle relaxers hydro 10s are good in there gallon of milk or can of coke or any open beverage in fridge (pills must be crushed and ground of course) and once they drink it it will act quick belive me those pills are amazing than once there out of it heavily fill up tub with water and than put the body in there stage it as an accidentall death due to the strength of the pills and we'll the tub. Than you go check wich beverage that person drink and empty in sink to be on extra safe side than leave back to your place start a fire pit in the back yard and throw all evidence in there to burn and never be seem again call friends over and have party around the fire. The toxicology report will show hey he was on muscle relaxers around the time of death and leave some pills on a desk or dresser in the bedroom of victim of coarse wear gloves and disposable clothing and shoes 2 size smaller who cares if your toes hurt nether that that getting cought:

The perfect murder can be done without getting your hands dirty and its legal just ask the FBI!! (Doxing) organized gang stalking

But, Xbow, then the murderer would have to find out a means of getting rid of all the clothes he/she would be wearing. Forensics would eventually catch up with him/her. Why not just commit the murder naked???

let time do its work. in the long run we all be dead. Why murder a 70 year old guy, risking spending the next 20 years in jail ? In the years he will be dead by natural causes.

I love forensics and not so soon there won't be a single thing in a person's dying that the whole forensics world will not be able to figure out. I'm sure With the use of computers, all the amazing medical tools, people's past history stored for the world to record, and the data base on all past types of deaths and how, who where and when also all being added to a data bases, there's not a single illness, accidental death, suicide or purposely caused death that this amazing database and use of a structured outline of procedures put into the pre-presumed data already in this deathly by cause data field that can not be figured out.

I mean, twenty years ago, we didn't even think DNA forensics were possible, so what stops us from putting all the physical, psychological and past history of each person, the rules of modern genealogy, the data of each areas distinct physical and geographic knowledge, plus all kinds of other data used to solve crimes all over the world...well, who knows what can be solved? Just takes the work of a few geniouses to put all the data into one computer and to connect it to robots and medical machinery then connect it into all world available data bases to make it happen. It would eliminate slouch te, man hours and guessing.

Oh and scott, the one who commented above about, how "God see's everything?", even if it were true what does this have to do with solving the problem? As for your moral issue, if God sees knows all, why them does he allow sickness, death, murder, etc...??? If GOD is so powerful, none of the discovery would be necessary, after, if he were such a good and moral GOD?

This is a ridiculous and misleading documentary.... Take a look at the number of unsolved murders - they solve only about 60% of murders in the US - not even counting those that manage to avoid scrutiny by appearing to be suicides or accidents. Give me a break with this nonsense.

Get elected president and you can kill as many children, women, and men as you like. Just ask Barack Obama, George W. Bush, and Bill Clinton. These three men killed more people than all the murderers in the history of the US combined.

The trick to getting away with murder is not concealing the murder, but preventing any charge from sticking in court. Creating enough reasonable doubt and keeping silent if you ARE questioned should let you walk.

What the h*ll is going on in this world!??? Doc.s showing how to murder.....the correct way!.......well it is for educational purposes. You think they would throw in on how to commit the dumbest murder and then flip the titles.

Well, since they don't have a dumb murder guide video, I feel it is my duty as an active member of Dummies-n-the Room to illustrate how a secret society of retards found a way to kill. Here's a few.
> Dummy +photo: MURDER and a Resume!<
1.) Go into a market and grab the victims hair. Then forcefully drag them outside and make them lay on the ground while you pick up a Pogo stick and begin to hop around a few times to get some rythm going and then jump for joy on their face while singing some gangster rap.

2.) Stop at a bridge toll booth around rush hour and grab the toll booth attendent and throw him off the bridge. Get back in your car and wait patiently in line until it's your turn to pay.

3.) Bring your enemy into a crowded church and drown them in the Baptismal water telling the pastor your just cleansing him of his sins!

4.) Take an enemy behind one of the targets at a shooting range and beat them to death with the blunt end of a pistol.

This is only for entertainment puposes only.

If the experts in this docu. are that good, then where were they during Casey Anthony's murder trial? And there sure does seem to be an aweful lot of people out there that have gotten away with murder. 9/11 is still unsolved.

Kinda funny how even watching this documentary could be used as evidence against anyone dumb enough to try to put this hypothesis to execution. The FBI can track your search history for 5 years, trace it to your IP address, proxy servers don't work for the most part. LOL you better be watching this from the library under someone else's card.

I thought it was really entertaining! I'm a big Hitchcock buff so this is cool. The narrator's voice was chilling.

The documentary is trying to discourage you from attempting 'a murder', by providing tons of examples from previous murders cases where the murderer has been caught. Im sure there is over a hundreds of thousands of unsolved cases, where people successfully got away with murder. Don't fall under the propaganda of this documentary my friends! :)

Interesting. I too question the motive of these film-makers in showing the general public what mistakes murderers make that gets them caught.

Did no one else notice that it's a British show with a TON of American content? If it was an American show with a ton of British content, they would not have a naked penis visible on the cadaver model. What's with all the nakedness on British TV? :P

Why? WHY!? Why would anyone set out to formulate the perfect murder? And then document how it would go down?

You're dumb.
And here's why: first, you dont know that there is no god; second, if there is a god that doesn't necessarily mean that humans are the center of the universe; and third, it sounded like Scott was making a joke and thers's no point in starting a mind-numbing religious dicussion on a video about forensics.
Your ideas are unorigional and they bore me.

Scott, there is no God. It may be a scary concept that man is not the centre of the universe, but it is nevertheless true.
Just thought you should know.
