Disposal of human corpses

A burial is usually accomplished by excavating a pit or trench, placing the deceased and objects in it, and covering it over. Humans have been burying their dead since shortly after the origin of the species. Burial is often seen as indicating respect for the dead. It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones.

Cremation is also an old custom; it was the usual mode of disposing of a corpse in ancient Rome (along with graves covered with heaped mounds, also found in Greece, particularly at the Karameikos graveyard in Monastiraki). Vikings were occasionally cremated in their longships, and afterwards the location of the site was marked with standing stones.

Since the latter part of the twentieth century, despite the objections of some religious groups, cremation has become increasingly popular. Jewish law (Halakha) forbids cremation, believing that the soul of a cremated person will be unable to find its final repose. The Roman Catholic Church forbade it for many years, but since 1963 the church has allowed it, as long as it is not done to express disbelief in bodily resurrection. The church specifies that cremated remains are either buried or entombed; they do not allow cremated remains to be scattered or kept at home. Many Catholic cemeteries now have columbarium niches for cremated remains, or specific sections for those remains. Some denominations of Protestantism allow cremation; the more conservative denominations generally do not. The Eastern Orthodox Church and Islam also forbid cremation.[1]

Among Hindus, Jains, Sikhs and some sects of Buddhists such as those found in Japan, cremation is common.

Immurement of corpses is the permanent storage in an above-ground tomb or mausoleum. A tomb is generally any structurally enclosed interment space or burial chamber, of varying sizes. A mausoleum may be considered a type of tomb, or the tomb may be considered to be within the mausoleum.

Sky Burial allows dead bodies to be eaten by vultures on open grounds or on top of specially built tall towers away from human sight. It is more ecological to allow the dead bodies to be quickly eaten by the highly evolved vultures than burials in which the dead bodies slowly rot in the soil and are eaten by the maggots and bacteria. Sky Burial is also more eco-friendly than cremation, which wastes dead bodies, requires fuel and produces air pollution. Sky Burials can be followed by optional automatic cremations of the skeletons left behind. Ancient Persians, Tibetans and some Native Americans practiced sky burials.

"Burial at sea" in past generations has meant the deliberate disposal of a corpse into the ocean, wrapped and tied with weights to make sure it sinks. It has been a common practice in navies and seafaring nations; in the Church of England, special forms of funeral service were added to the Book of Common Prayer to cover it. In today's generation, "burial at sea" may also refer to the scattering of ashes in the ocean, while "whole body burial at sea" refers to the entire uncremated body being placed in the ocean at great depths. Laws vary by jurisdictions.

The concept may also include ship burial, a form of burial at sea in which the corpse is set adrift on a boat.

Rarer forms of disposal of the dead include exposure to the elements and to scavenger animals. This includes various forms of excarnation, where the corpse is stripped of the flesh, leaving only the bones, which are then either buried or stored elsewhere, in ossuaries or tombs for example. This was done by some groups of Native Americans in protohistoric times. Ritual exposure of the dead (without preservation of the bones) is practiced by Zoroastrians in Mumbai and Karachi, where bodies are placed in "Towers of Silence", where vultures and other carrion-eating birds dispose of the corpses. In the present-day structures, the bones are collected in a central pit where, assisted by lime, they, too, eventually decompose. Exposure to scavenger birds (with preservation of some, but not all bones) is also practiced by some high-altitude Tibetan Buddhists, where practical considerations such as the lack of firewood and a shallow active layer seem to have led to the practice known as jhator or "giving alms to the birds".

A body farm involves a similar method of disposal as an object of scientific study.

In some traditions, for example that practiced by the Spanish royal family, the soft tissues are permitted to rot over a period of decades, after which the bones are entombed.

Mummification is the drying of bodies to preserve them. The most famous practitioners were ancient Egyptians—many nobles and highly ranked bureaucrats had their corpses embalmed and stored in luxurious sarcophagi inside their funeral mausoleums. Pharaohs stored their embalmed corpses in pyramids.[2]

Promession is a new method of disposing of the body. Patented by a Swedish company, a promession is also known as an "ecological funeral". Its main purpose is to return the body to soil quickly while minimizing pollution and resource consumption. It consists of separating the body from the coffin, freezing it with liquid nitrogen, vibrating it into small particles, freeze drying it, separating any metals, and placing the dry powder remains in a biodegradable casket in top soil.[3]

Composting turns organic matter into soil conditioner. For human corpses, it can be performed by placing the body in a mix of wood chips, allowing thermophile microbes to decompose the body.[4] In the United States, this method is only legalized in Washington.[5]

Dissolution involves the breaking down of the body by solvation, e.g. in acid or a solution of lye, followed by disposal as liquid.

A specific method is alkaline hydrolysis (also called Resomation). Advocates claim the process is more environmentally friendly than both cremation and burial, due to CO
2 emissions and embalming fluids respectively. On the other hand, many find the idea of being "poured down the drain" to be undignified.[6]

• Donation for study – donation to a medical school or similar – after embalming and several years of study and dissection the body is usually eventually cremated.
• Space burial
• In cases of war, genocide, or natural disasters including disease epidemics, large groups of people have been buried in mass graves or plague pits.
• Dismemberment, in which the body is divided and different body parts are dealt with separately; for example in the case of the Habsburg royal family as well as the display of the relics of various saints.

Disposal of this type happens for various reasons, including the main difference between a burial at sea and a burial on land: the difficulty in recovering the body. Sometimes this difference is desired to dispose of bodies outside of the law.

There may be a number of reasons for this kind of crime. One common reason for this behavior is to dispose of the evidence. The body may be the victim of a homicide, as for example murder or manslaughter. In some cases, the victim may even be still alive and drowning during the process. A live victim is usually restrained to reduce the likelihood of the victim freeing themselves or fighting back, and the body is often weighted to ensure the sinking of the body. The Mafia is infamous for disposing of victims in oceans or lakes with their feet cast in a concrete block. Other variants tie concrete blocks or other heavy objects to the victim. The Chicago-style method involves wrapping heavy chains around the victim. In Venice, barrels filled with a human body and concrete are occasionally found in the canals. It is difficult to determine if murder victims buried in a swamp are buried in water or in earth. Often, the body is also cut up to reduce the likelihood of reappearing.

In other cases, the victim may have died from an accident, and another involved party tries to destroy evidence of the accident. There are also cases where a stillborn infant is buried to dispose of evidence of infidelity, or problems with fertility, or the shame associated with unwed parenthood in many cultures.

While a corpse properly buried at sea is unlikely to reappear, many criminals are unable to ensure the permanent disposals of a body, and evidence of the body may reappear. This is rarely as spectacular as the freshly caught shark in the Sydney Coogee Aquarium that vomited up a surgically separated human arm, leading to a murder investigation. That victim was determined to be James Smith, but the three murder suspects were acquitted.

Many criminals dispose of bodies in a river, hoping that the body is carried away. However, this method will most likely lead to a quick detection of the body, because the body gets entangled at the side of the river, or stopped at a dam, or is simply seen floating by others. A disposal in large lakes or oceans is more likely to hide the body, but a decomposing body can develop a strong positive buoyancy due to the decomposing gases being trapped underneath the skin. This may bring the body up to the surface, or at least increase the movement across the ocean floor due to wave actions. Many bodies have washed up at the shore. Bodies have also been discovered in the nets or lines of fishermen, and occasionally, bodies are also discovered by divers.

Very cold water with little oxygen may even preserve bodies, allowing for an easier identification, as for example Margaret Hogg, the Wasdale Lady in the Lake in Wast Water lake in the Wasdale area (see National Trust Properties in England). She was found after 8 years, with her body preserved like wax.

• Gary Ridgway (born 1949), the Green River Killer, disposed most of his bodies in or near the Green River.
• In the Shark Arm Case, James Smith's murder was discovered when a shark in the Sydney Coogee Aquarium vomited up his severed arm in 1935.
• Anne Marie Fahey, scheduling secretary for then Delaware Governor Thomas Carper, was killed by prominent Delaware attorney Thomas Capano, and her body was dumped inside of a large "Igloo" cooler into the Atlantic Ocean off the New Jersey coast with the help of his brother, Jerry. However, because the cooler would not sink, despite Capano repeatedly shooting holes into it with a shotgun, the body was removed and weighted down with an anchor to make it sink into deeper water. The body was never recovered, but the cooler was later found washed up onshore by fishermen, and remains today in the evidence locker of the New Castle County Courthouse in Wilmington, DE.
• Emmett Till's body was dumped in the Tallahatchie River in Mississippi in 1955.
• John Roselli's body found in Miami Florida Bay in 1976.
• Margaret Hogg, the Wasdale Lady in the Lake, was murdered 1976, and found 1984.
• Laci Peterson, the wife of Scott Peterson, murdered 2002 and found on the shore of the San Francisco Bay.
• Quang Lu, a Thornhill, Ontario loan shark was found entombed in a rusty steel barrel full of concrete in Lake Ontario after police received an anonymous tip.[8]
• Serial killers John Wayne Gacy and Jeffrey Dahmer disposed their victims' bodies in the Des Plaines River.
• The 1990s film Amistad, depicts a group of slaves being chained and then thrown alive into the sea to die by drowning. This method was applied by crews of slave-trade ships.
