Joseph Scott Morgan: 人们总是问我如何处理腐烂的尸体。我逐渐习惯了这种工作，但我永远无法完全适应。我将腐烂视为正常的生物过程，类似于出生。为了找到真相，我必须克服尸体的气味和景象，专注于科学。人体腐烂是最好的老师，它能帮助我们了解死亡的时间和原因。血液分解后会产生难闻的气味，尸体在不同阶段会呈现出不同的特征，如腹部变绿、四肢肿胀、皮肤脱落等。这些特征可以帮助我们判断死亡时间，讲述死者的故事。 Dave Mack: 我对腐烂过程并不熟悉，所以想请教您一些问题。您提到尸体在24到36小时内会出现外在的腐烂迹象，那么在更短的时间内，比如在爱达荷州谋杀案中，尸体在11到12小时内会有什么变化吗？还有，如果一个人切除了阑尾，腹部还会出现绿色的变色吗？

Chapters
Professor Joseph Scott Morgan discusses the process of human decomposition, explaining how it's a natural biological process, similar to birth, and emphasizing its importance in death investigations. He addresses common misconceptions, such as the immediate release of bodily fluids upon death.
  • Decomposition is a natural biological process.
  • It begins at a cellular level immediately after death.
  • Initial stages may not be visible or noticeable, but changes occur at the cellular level.
  • The body's own enzymes begin to break down tissues (autolysis).
  • Bacteria and microorganisms contribute to decomposition (putrefaction).
  • Environmental factors, especially heat, influence the rate of decomposition.

Shownotes Transcript

Joseph Scott Morgan puts on his teachers cap and explains decompositional changes and what really happens in the first minutes, hours, and days after death and tells the story of a rookie cop doing a simple welfare check calls for backup after finding a victim dead in his tv chair. The still wet behind the ears cop thinks the victim was killed with a hatchet, but all of the blood and body fluid appearing on the victims' shirt is not from a hatchet, the man had a heart attack. Joseph Scott Morgan and Dave Mack talk about the disintegration of body tissues after death, known as decomposition as well as the two processes of Decomposition and how important these processes will be in the upcoming trial of Bryan Kohberger for the murders of four college students in Idaho.
