How long does it take for a body to decompose?
HUMAN decomposition is a natural process that occurs in four stages after death.
As soon as the heart stops beating, cells are deprived of oxygen and start to lose their structure.
What happens to the organs after death?
Once your body shuts down, decomposition begins several minutes after death with a process called autolysis.
Body decomposition is a process that involves the breakdown of tissues after death.
It's a natural process that varies based on ph and oxygen level, the cause of death, weather, temperature and even the moisture level.

When does human decomposition start and how long does it take?
Within 24-hours of death, the internal organs starts to decompose. In three to five days, the body starts to bloat releasing bodily fluids.
After 10 days, the body turns from green to red because there is no oxygen and gas takes up residence.
Several weeks after, the nails and teeth fall out. A month after death, the body starts to liquify.
The length of time a body decomposes depends on a few factors. It depends on the environment and predators.
What are the four stages of decomposition?
Senior staff scientist at Oak Ridge National Laboratory, Dr Arpad A.Vass, said that human decomposition happens in four stages immediately after death.
It begins with autolysis, the first stage in the process that destroys the internal organs. This process begins immediately once the organs are deprived of oxygen causing an acidic environment. This is where rigor mortis sets in, causing the muscle stiffening.
The second stage is bloat and this is when bacteria is released causing skin discoloration and the human body doubles in size. This stage produces unpleasant odors called putrefaction and tends to linger even after a body has been removed.
The third stage according to Dr Vass is active decay. At this point, fluids are released through the the body's orifices. The organs, skin and muscles liquify indicating the beginning of active decay leaving hair and bones intact.
Even though it takes a month for the body to liquify, there is no set time on when skeletonization occurs. According to Dr Vass, it's the final stage in body decomposition.
Who was Brian Laundrie and what happened to him?
Brian Laundrie was the fiancé of Gabby Petito, who went missing in late August during a road trip from New York to Oregon with Brian.
Brian was eventually named a person of interest in the case of Gabby's disappearance.
His remains were officially identified on October 21, 2021, after an extensive search at Myakkahatchee Creek Environmental Park.
The FBI released a statement after it was confirmed that the human remains found in the search for Brian were bones.
The statement read: "On October 21, 2021, a comparison of dental records confirmed that the human remains found at the T. Mabry Carlton Jr. Memorial Reserve and the Myakkahatchee Creek Environmental Park are those of Brian Laundrie."
