The 25-year-old Taoyuan woman was burned alive? Forensic doctor Gao Dacheng reveals key clues

A neck-cutting and arson case occurred in Taoyuan. A 25-year-old woman surnamed Lu who returned home at night had her throat cut and her body burned. The 36-year-old man surnamed Lin involved was arrested by the police after committing the crime. The Taoyuan District Court ruled on the evening of the 12th that he would be detained without permission. The outside world is concerned about whether Ms. Lu was burned alive during her lifetime or her body was cremated after her death. Forensic doctor Gao Dacheng said that traces of the respiratory tract, skin and eyelashes will be key clues.

Because Ms. Lu had stab wounds and burns, Gao Dacheng said that the first priority was to conduct an autopsy and observe the respiratory tract of the deceased. If the deceased was burned to death, carbon particles or hot air must be inhaled into the trachea because he was still breathing. On the contrary, if the body was set on fire after death, the respiratory tract is usually cleaner because there is no breathing function, and there will not be the same level of evidence of inhalation.

In addition, "blisters" on the skin are also important evidence. If the body was burned before death, blisters will appear on the skin due to blood circulation and tissue reactions. On the contrary, if the body was burned after death, the physiological circulation has stopped, and the skin will only appear burnt.

Gao Dacheng also pointed out that the eyelashes are also an important observation evidence. If there is a fire alarm before death, the natural physiological reaction will be to close the eyes, and the eyelashes will not be burned out. At the same time, it can also be judged by the distribution of burns. If the burns are on both sides, it means that the body was struggling and rolling during life, while the burns on one side are mostly abandoned and burned after death.

Because Mr. Lin has been ruled to be detained without permission, the relevant evidence needs to be further clarified by the prosecutor.
