Do not spend an inordinate amount of time examining the locationg of your crime, either before or after.
If there is any knowledge of tension between the two of you, don’t try it.
If you befriend him, the Police will come knocking, and if your story doesn’t check out against the other witness’ stories, you’re in hot water.
DNA, Forensic, Fingerprinting- it doesn’t mean jack squat unless they’ve already found you and can get DNA samples and fingerprints.
The perfect murder should involve framing someone. Once the D.A. has a suspect, the public opinion teeters to that person and will refuse to let him/her go.
Your alibi should consist of being in a public area with lots of people, where no one would really remember you being there if you actually were- A concert, a rave, etc.
If you want your victim to remain a John/Jane doe, knock out all the teeth and burn the body.
Poison syringes are the best weapon to use. I’m recalling an incident during the Cold War in which the killer hid the syringe in the type of his umbrella, then “accidentally” bumped into the victim.
If you’re not working for the mob, make it look like a mob hit(Mercury-tipped or hollow-tipped bullets, three shots). If you ARE working for the mob, make it look like a non-mob hit.
Take the murder weapon with you and put inside the car of whoever you want to frame. So they don’t notice it but the police do, stash it under the back seat.
In addition to your primary target, pick, at random from a phone book, about four other secondary targets. Kill all five people (with your primary target second or fourth) on the same night in the same manner. The investigators will connect all five murders to the same killer. You will not be a reasonable suspect because you only met one of the five victims. Since the five victims have probably never met one another, the investigators would spend their energy searching for an indiscriminate killer (serial killer). After all, this appears to be a group of five totally random murders.
And of course, follow the basic rules. Have an alibi, wear gloves, blah, blah, blah…
IANAL and I can’t speak for Japanese law, but in the United States the statute of limitations can be stopped from tolling (running out) for a number of reasons. Fleeing the jurisdiction stops the s.o.l. from tolling, as does action taken in furtherance of the crime or in furtherance of a conspiracy. Some jurisdictions also allow “John Doe” warrants, which allow for an indictment of an unknown defendant based on physical evidence. A recent case which got a lot of press in New York dealt with a John Doe warrant issued in a rape case on the basis of DNA evidence.
As also previously noted, there is no statute of limitations on murder.
Yes, I know there is no statute of limitations for murder in the US. Also, in Japan fleeing the jursidiction (i.e., going overseas) will cause the clock to stop ticking. Nevertheless, there have been cases of “perfect” murders that we know of because the murderer waited 15 years and then publicly announced what he or she had done, after it was too late for the police to do anything.
Check this out, specifically rules 5 and 10, and the end. George Joseph Smith would have committed a perfect murder, if he hadn’t done the same thing three times. Neill Cream would have if he didn’t recommend the coroner exhume the body and check for foul play.
This made me think of any number of stories in which a person fakes his or her own death and then disappears. If they succeed, they’ve essentially committed “murder” (of the person they used to be) and if they go on to live a happy successful life, with no one ever finding out, that would be a perfect murder, with no one hurt.
Maybe even better would be something like the episode of MAS*H in which Hawkeye invents the saintly Captain Tuttle, and then has him “killed” when things get too complicated. A perfect murder (although technically not murder in that case – Captain Tuttle jumped from a helicopter without a parachute), with no victim.
the perfect murder is one where none can prove it was a murder.
consider this-
you and your victim are out hiking in the mountians. he or she falls a great hieght. no witnesses.
can the police prove it was an accident? or was there a shove?
they may suspect, or even know you killed him or her. but they can’t prove it.
any half way decent lawyer should be able to get you off.
