Mechanisms and Causes of Death

The video tutorial covers the investigation of death, focusing on the manner, cause, and mechanism of death. It explains the five manners of death: natural, accidental, suicidal, homicidal, and undetermined, with examples to illustrate each. The cause of death is discussed in terms of the injury or disease leading to death, including proximate causes. The mechanism of death is described as the physiological changes causing death, with examples such as blood loss or organ failure.
