Rigor Mortis - rigid death
Livor Mortis- Bluish death
Algor Mortis- Cooling death

Use the forensic names-no nick names (bloat,active,etc.)
Initial Decay
Putrefaction
Black Putrefaction

Post Mortem Interval: Time between death and when the body was found

what is a group of crows called?
a murder

What is the importance of the glacier equation in forensic science and what mortis does it belong to?
Helps determine time of death by using temperature of the body

what are the two bugs that eat away hair AND which stage does this occur?
Moths and Mites

what 2 insects are most commonly found on a decayed corpse?
Beetles & Flies

What are 3 factors that will impact the rate in which the body cools?
We discussed several :)
1.Temp of the environment
2.Type/Amount of Clothing on the victim
3. Wetness of the Clothing
4. Is there air movement? (In a bag, buried,etc.)
5. Size of the individual
6. Was the body engulfed in water?

_______________ is the process of digestive enzymes breaking down muscles and other parts of the body during decay. It occurs in stage _______ of decay and is essential to the process of ___________ Mortis.
Autolysis is the process of digestive enzymes breaking down muscles and other parts of the body during decay. It occurs in stage 1 of decay and is essential to the process of Rigor Mortis.

What is the significance of the 1.5 in the glacier equation?
+200 pts if you can CORRECTLY provide the glacier equation.
1.5 is significant because it is how many degrees the body cools PER HOUR (on average) after death
98.4 - current temp / 1.5 = estimated T.O.D

what is the monkey's name in the movie Aladdin?
Abu

part 1: What does each mortis allow investigators to determine?
Part 2: What do investigators use to determine this for EACH mortis?
Rigor mortis= Time since death by looking @ stiffness
Algor mortis= Time since death by looking @ internal temperature of the body
Livor mortis= Position of the body after death/if the body has been moved by looking @ lividity

A body is found. The body has collapsed and the liquids from the body have seeped into the soil. What stage is this? Give me the actual name, not #
Black Putrefaction

what is this insect?
Hint: think about the lifecycle we talked about. what was the name of that particular fly?
Blowfly
400
the vocab word/phrase that refers to a species that may feed on a fresh corpse while other species may show up weeks later
Species Succession

what state is this?
Indiana!!

What causes rigor mortis?
In other words, what causes muscles to stiffen?
ACID BUILDUP IN THE BODY!
After death, your body goes in fight or flight still trying to survive. even though you aren't breathing in oxygen, your body converts lactic and pyruvic acid as a 2nd source of energy. Changing the body's pH- too acidic!!
500
what are the two smells that makes up the scent of death?
No- I will not count off if you spell them wrong
Cadaverine and Putrescine

There was a particular fly that I mentioned would most likely be found in stage 4 of decay... what was the name of that fly?
Hint: think about what stage 4 is and what occurs in that stage
Cheese Skipper Fly!

Other than Weather factors, what were the other 3 questions entomologists consider when determining the PMI? Below is 1. give me the other 2.
Hint: We discussed 3...One of them is: Were there other species of bugs that may have eaten the maggots we use to analyze?
Did the victim ingest drugs or were poisoned at the time of death, thus either slowing down or speeding up the insect's life cycle?
Was the body enclosed or wrapped in a material preventing the flies from finding the corpse?
