Suicide methods

A suicide method is any means by which someone purposely kills himself/herself. Methods that have been used to commit suicide include:

Bleeding

Exsanguination is a method of death which is caused by blood loss. It is usually the result of damage inflicted on arteries. The carotid, radial, ulnar or femoral arteries would be targeted.

[edit] Cutting wrists

This entails cutting through the wrists & may damage the tendons, ulnar and median nerves which control the muscles of the hand, which can result in temporary or permanent reduction in sensory and motor abilities. [1]

It is not an immediately lethal method, as the arteries tend to try to spasm shut in response to blood loss. Bleeding to death by veins is even harder and rarer. It can take a few hours or even more to finally die from the blood loss, depending on a number of variables. It is popularly believed that wrist-slashing is more lethal if the cut is made along the length of the arm than across, due to the difficulty of repairing a lengthwise cut of a blood vessel. However, this method has little effect on mortality: while it is indeed much harder to repair the damage after the danger of blood loss has passed, it is no more difficult for rescue workers to prevent bleeding via compression, torniquette and other standard methods.

[edit] Cutting the carotid artery

Cutting through the throat is one method of exsanguination. Damage is inflicted to the carotid artery which carries blood to the brain, and it takes no longer than a few minutes to lose enough blood for death to occur, although death could also be caused by blood clogging the trachea. People who do this often cut the recurrent laryngeal nerve, the nerve that goes up to the voicebox and larynx, and lose their voices.

It was also practiced as a ritual suicide method in Japan, by noble women for the same purposes as seppuku was used by men.

Carbon monoxide poisoning

A particular type of asphyxia involves inhalation of high levels of carbon monoxide.

Death usually occurs through hypoxia. In most cases carbon monoxide (CO) is used because it is easily available as a product of incomplete combustion; for example it may be released by cars and some types of heaters.

Carbon monoxide is a colorless and odorless gas, so its presence cannot be detected by sight or smell. It is harmful to humans since the CO molecules attach themselves irreversibly to hemoglobin in the blood, displacing oxygen molecules and progressively lowering the body's oxygenation, eventually resulting in death.

In the past, before air-quality regulations and catalytic converters, suicide by carbon monoxide poisoning would often be achieved by running a car's engine in a closed space such as a garage, or by redirecting a running car's exhaust back inside the cabin with a hose. Motor car exhaust may have contained up to 25% carbon monoxide. However, catalytic converters can eliminate over 99% of carbon monoxide produced.[2]

The incidence of suicide by carbon monoxide poisoning through burning charcoal within a confined space appears to have risen.

Drowning

Suicide by drowning is the act of deliberately submerging oneself in water or other liquid and staying there long enough to prevent breathing and deprive the brain of oxygen. Genuine cases of drowning are determined by whether the victim's lungs are filled with water. As with other deaths by suffocation, if the drowning is stopped before death, oxygen deprivation can cause brain damage.

[edit] Drug overdosing

Suicide by pharmaceuticals ("overdosing") is a method which involves taking medication in doses of several times greater than the indicated levels, or in a combination which will enhance each drug's effect. Due to the unpredictability of dosing requirements, death is uncertain, and an attempt may leave a person alive but with severe organ damage (which may prove eventually fatal itself). Drugs taken orally may also be vomited back out before being absorbed.

Painkiller overdoses are among the most common[4] due to easy availability of over-the-counter substances. Overdosing may also be performed by mixing medications in a cocktail with one another or with alcohol or illegal drugs.

This method may leave confusion over whether the death was a suicide or accidental, especially when alcohol or other judgment-impairing substances are also involved.

[edit] Electrocuting

Suicide by electrocution involves using a lethal electric shock to kill oneself. A high enough voltage can overcome the high resistance of the skin and pass a sizable current through the body. A large alternating current through the body can seriously disrupt nerve signals and can cause the heart to go into fibrillation.

[edit] Explosives

Suicide by explosives involves putting explosives in bodily orifices or otherwise setting off explosives in near proximity. A sufficient quantity of explosive would cause death almost instantaneously by blowing the body into so many pieces that life would end instantly. Shattered organs, broken bones, internal bleeding from the blast wave and burning would be the causes of death in other cases.

Suicide

Hanging is a common method of suicide. The materials necessary for suicide by hanging are relatively easily available to the average person, compared with firearms or lethal poison. Full suspension is not required, and for this reason hanging is especially commonplace among suicidal prisoners. A type of hanging comparable to full suspension hanging may be obtained by self-strangulation using a ligature of the neck and only partial weight of the body (partial suspension). This method is dependent on unconsciousness produced by arterial blood flow restriction while the breath is held.

  • In Canada, hanging is the most common method of suicide,[2].
  • In the U.S., hanging is the second most common method of suicide, after firearms,[3].
  • In Great Britain, where firearms are less easily available, as of 2001 hanging was the most common method among men and the second-most commonplace among women (after poisoning).[
Hanging

Main article: Hanging

Suicide by hanging.

The traditional death penalty of hanging by gallows consists of a rope tied to some fixed object (i.e. the gallows), with one end tied into a hangman's noose and put around the neck. The person falls through the release of a trap door (or jumps, in the case of suicide) from a height, and death is instantaneous due to breaking of the neck. If the neck is not broken, asphyxiation due to the obstructed trachea ultimately leads to death. Many people who attempt to hang themselves strangle themselves instead, and don't always die; they instead suffer brain damage from lack of oxygen.

Jumping

See also: Defenestration

Jumping from a great height can shatter organs and tissues. If a person jumps from a tall bridge into water, the person may die by impact rather than by drowning. Such jumpings off the Golden Gate Bridge, of which there have been 1,300 between 1937 and 2006, were depicted in the documentary film The Bridge.

The 68.6 metre plunge from the bridge has proven to be fatal in 98% of cases. The jumper would hit the water at 120 km/h (or about 77 mph). Most die of internal bleeding due to broken ribs which pierce the heart, lungs, liver or spleen. Survivors, who would have hit the water feet-first, would have often had their femurs shattered.[

Defenestration is the act of throwing someone or something out of a window. The word comes from the Latin de (from; out of) and fenestra (window or opening), and was coined around the time of the 1618 incident mentioned below.[1] Merriam-Webster's dictionary users named it as one of their favorite words of the year in 2004.[

Poisoning

Suicide can be committed by using fast-acting poisons, or substances which are known for their high levels of toxicity to humans. For example, the people of Jonestown, in northwestern Guyana, all died when the leader of a religious sect organised a mass suicide by drinking a cocktail of diazepam and cyanide in 1978.[6] Adolf Hitler bit into a cyanide capsule while simultaneously shooting himself in the head with a firearm. Sufficient doses of some plants like the belladonna family, castor beans and others also contain poison.

Seppuku

Main article: Seppuku

Seppuku (colloquially "harakiri") is a Japanese ritual method of suicide, practiced mostly in the medieval era, though some isolated cases appear in modern times. For example, Yukio Mishima committed seppuku in 1970 after a failed coup d'etat intended to restore full power to the Japanese Emperor.

Unlike other methods of suicide, this was regarded as a way of preserving one's honour. The ritual is part of bushido, the code of the Samurai.

Dressed ceremonially, with his sword placed in front of him and sometimes seated on special cloth, the warrior would prepare for death by writing a death poem. With a selected attendant (kaishakunin, his second) standing by, he would open his kimono, take up his wakizashi (short sword), fan, or a tanto (knife) and plunge it into his abdomen, making first a left-to-right cut and then a second slightly upward stroke. On the second stroke, the kaishakunin would perform daki-kubi, when the warrior is all but decapitated, leaving a slight band of flesh attaching the head to the body, so as to not let the head fall off the body and roll on the floor/ground; which was considered dishonorable in feudal Japan.

Shooting

Methods of suicide among persons aged 15-19. The use of a firearm is the leading method in the United States.

This method involves using a firearm to cause a fatal injury to oneself. It is used more frequently in countries where firearms are easier to obtain, and is the leading method in the United States. This method may still be used in countries where firearms are harder to obtain, in particular by people who use firearms in their work, for example soldiers or police officers.

Some studies have shown that in Western nations, men tend to use this method of suicide more often than women, which has been cited as one potential reason for the higher suicide success rate among men. Though most men shoot themselves in the head, women tend to shoot themselves in the heart.[7]

[edit] Suicide attack

Main article: Suicide attack

A suicide attack is an attack in which the attacker (attacker being either an individual or a group) intends to kill others and intends to die in the process of doing so. In a suicide attack in the strict sense the attacker dies by the attack itself, for example in an explosion or crash caused by the attacker. The term is sometimes loosely applied to an incident in which the intention of the attacker is not clear though he is almost sure to die by the defense or retaliation of the attacked party.

Such attacks are typically motivated by religious or political ideologies and have been carried out using numerous methods. For example, attackers might attach explosives directly to their bodies before detonating themselves close to their target, or they may use car bombs or other machinery to cause maximum damage (e.g. Japanese kamikaze pilots during World War II). Some sources refer to this as a "homicide attack", to emphasize the idea that killing other people is usually the primary purpose of such an attack[citation needed]. However, this usage is ambiguous since the word "homicide" already refers to unlawful killing and the key aspect of a suicide attack that distinguishes it from other forms of homicide is the death of the perpetrator.

Islamist extremist terrorists have engaged in suicide attacks numerous times in the Arab-Israeli conflict, and also against the West at other times. Perpetrators believe that the gains to others, or to a religious, political or moral cause, outweigh their personal loss and/or that they will be rewarded in the afterlife.

The September 11, 2001 attacks by Al-Qaeda using civilian aircraft on the World Trade Center and The Pentagon are examples of suicide attacks.

This also includes the Virginia Tech Massacre and the Chris Benoit case.

[edit] Suicide by cop

Main article: Suicide by cop

The term "suicide by cop" is used to describe a situation in which an individual behaves in a manner intended to provoke an armed law enforcement officer into use of lethal force against them. Common methods used involve charging at officers with a weapon, repeatedly refusing lawful orders in threatening situations, or driving a vehicle at officers.
