The study was carried out at the Southeast Texas Applied Forensic Science Facility in Huntsville. The body cells slowly lose their structural integrity and begin to break down, releasing cellular enzymes which break down cells and tissues in a process known as autolysis, decayed by the bodys own enzymes. Different groups of animals find the corpse attractive at different stages of decomposition and the resultant change in the animal community is called a succession. A brain to heart connection is made during viewing that helps you in the grieving process. In the absence of scavengers though, it is the maggots that are responsible for removal of the soft tissues. Once self-digestion is under way and bacteria have started to escape from the gastrointestinal tract, putrefaction begins. When that happens, fluids produced as a result of decomposition end up leaking from the casket. The so-called gut microbiome is one of the hottest research topics in biology at the moment.

At about this same point in time, the molecular structures of the cells in a casketed body break apart. A decomposing body significantly alters the chemistry of the soil beneath, causing changes that may persist for years. These final stages of decomposition, and the transition between them, are difficult to identify, because there are far fewer observable changes than at earlier stages.

Victims of trauma and violent deaths usually need extensive facial reconstruction, a highly skilled and time-consuming task. Based on these findings, it appears that if enough corpses are studied with long-term timelapses to generate statistical data on post-mortem movement, that knowledge could be used to analyse crime scenes with greater accuracy in the future.
