Watching documentaries on the Casey / Caylee Anthony case. How tf did the jury come to the conclusion that Casey Anthony was not guilty? I’m really having a hard time wrapping my head around this. There is so much evidence.
forensics is such a fun class because we really just learn how mysterious deaths go unsolved and how crime scenes and murders get investigated and like wow. we could really just commit murder or fake our own deaths and get away with it huh
Question- What Are the Most Popular Methods of Searching a Crime Scene?
Answer-
The scene and conditions may determine the search method to use. For example, the size of the crime scene and the number of people available to conduct the search may play a role in determining the best method to use.
Following are the most popular search methods, usually commissioned on the crime scene:
Strip Method:
The strip method crime scene investigation technique, also called the line method, requires that investigators stand in a line, then begin to walk parallel to one another across the crime scene. Once they have concluded their investigation and reached the other side of the scene, they turn around and walk back, following the exact same path they had walked on the first pass.
Spiral method: Here the search is started from one end of the crime scene, carried out in spirals till the focal point of the crime scene.
It involves a spiral into (inward) or out from (outward) a crime scene. A practical disadvantage with outward spiral searches is the evidence may be destroyed as the searchers move to the center of the crime scene area to begin their outward search.
Zone method: The scene is divided into small zones and each zone is examined in turn.
Grid Method: In the grid search method, the IO begins like a strip search. After completing the search by horizontal lanes, he searches back at right angles to the original strip This search from two different angles helps in the recovery of evidence which may be missed in simple strip method.
Difference Between Hospital Autopsy and Medicolegal Autopsy
Asphyxiation:
Asphyxiation is a term that describes death that occurs due to the lack of oxygen. This lack of oxygen affects the functioning of the brain, which in turn catastrophically affects the functioning of the remainder of the body.
Asphyxiation can be caused by a number of events.
Strangulation, the deliberate squeezing of the neck, can cut off oxygen to the brain.
Other accidental or deliberate means of asphyxia include suffocation, where air movement into the body through the nose and mouth is restricted. Someone being smothered by a pillow is an example of suffocation.

Illustrations from Dr. Ziemke’s chapter on bloodstain pattern analysis. The 2 figures demonstrate a drip effect from walking nd running.
Ziemke added the arrows to show directionality evident in the stains.
