Study Notes
Time of Death
- Stomach and intestinal contents can be used to estimate time of death
- Stages of decomposition can also be used to estimate time of death
Forensic Entomology
- Insects can be used to recreate the post-mortem time period
- Insects can serve as valuable evidence to help estimate time of death
- Life cycle of insects can be used to estimate time of death
Pathology and Death Investigation
- Autopsies provide information in a death investigation
- Manner of death can be classified as homicide, accidental, or undetermined
- Cause of death can be determined through autopsy
- Mechanism of death can be determined through autopsy
- Examples of manner, cause, and mechanism of death include:
- Jon Benet Ramsey: homicide, strangulation, asphyxiation
- Whitney Houston: accidental, drowning, combination of heart disease and drug use
- Death by gunshot: homicide, gunshot, massive blood loss
- Death by drug overdose: undetermined, drug overdose, heart failure
Steps in an Autopsy
- Specimens collected for toxicology lab analysis include:
- Blood from aorta
- Urine from bladder
- Vitreous humor from eyeball
- Histology samples (tissue embedded in wax)
- DNA
- Elapsed time can be estimated based on body temperature and stiffness
Unit 8 Wrap-Up
- Review notes and ask for help if necessary
- Use highlighters or different colors to chunk and group sections of notes
- Write quiz questions in the margin for confusing topics
- Summarize and reflect on essential questions, connecting to prior thinking or other classes.
