What happens to a dead body after 3 weeks in water? After about three weeks in water, a dead body undergoes putrefaction where tissues break down and form the soapy fatty acid known as “grave wax” which halts bacterial growth. Additionally, the skin of the body may turn greenish black due to blisters from the decomposition.
Rigor mortis and livor mortis are typically present in bodies recovered from the water though the onset and waning of these classic postmortem changes may be altered by water temperature, current, changing of body position due to movement, and level of activity prior to death. Pink discoloration of the teeth and gums, an observation once ...
Aug 16, 2021 · Bloating begins a few days after death as gases collect, decomposition around a week or two afterward, and the dry stage (in which the remains largely consist of just bone and other tough materials such as cartilage) is reached a few weeks to a month after the person's demise. Advertisement. These changes, Forensic Digest goes on, are affected ...
- Stage 1 Fresh (1-2 days) This stage begins almost instantly from the moment of death. As the heart stops beating, the body’s cells gets deprived of oxygen and pH changes occurs.
- Stage 2 Bloated (2-6 days) This stage of decomposition includes the first visible signs of decay, namely the inflation of the abdomen due to a build-up of various gases produced by bacteria inside the body.
- Stage 3 Decay (5-11 days) The previously inflated carcass now deflates and internal gases are released. As the tissues break down the corpse will appear wet and strong odours are very noticeable.
- Stage 4 Post-Decay (10-24 days) By the time this stage is reached, decomposition slows, as most of the flesh has been stripped from the skeleton, though some may remain in denser areas such as the abdomen.
Water Depth – Generally speaking, the deeper you travel into a body of water, the colder it gets. This is because cold water sinks below less dense warm water found at the surface. Temperature – Depending on the body of water, the cooler temperatures of the water allow for a slower body decomposition. Water Currents – Strong currents ...
In a series of 1590 bodies recovered from water, Lunetta et al (2002) found external foam in 29%, froth in the airways in 70.6% and overlapping of the lung margins in 64.1% of ‘fresh bodies’ of ‘verified drownings’; the combination of all three was present in only 8.8% of cases, but was said to be ‘100% specific for drowning’.

Apr 7, 2024 · Looking at the factors listed here, it is easy to understand that there would be a significant impact on the decomposition of the human body when in water. Exposure to moisture and water can accelerate decomposition - the opposite of a body being immersed or fully submerged. The putrefaction stage, for example, ideally occurs at temperatures ...
