Crime Scene Investigation

Michael E. Kelly decided one morning to eat out for breakfast. After a mental debate he chose to go to Salt Works II, a decision that he would ultimately regret. As he was driving into the parking lot, Kooladria Jones and Ralph Johnson were waiting for a good car to break in, and since Mike Kelley decided to park away from the mysteriously empty Salt Works II parking lot, the happier the evildoers were. While Mike Kelly was ordering his breakfast, Kooladria and Ralph were secretly breaking into his car. Unfortunately, his wallet was in the car. During the process, the evil duo stole Mike Kelly's money and nearly left until Ralph noticed a diamond ring, an expensive diamond ring. One found only in a showcase lying right on the passenger seat. A happy couple took the ring and Ralph wrote a note stating "I have your diamond ring". The two ran off.
After finishing a refreshing meal of brains and eggs, Mike Kelly went to pay for his breakfast but realized he left his wallet in his car's cupholder. He ran to his car and noticed the windows had been broken. Realizing what had happened, the flustered Mike Kelly called the police first and then went to the cashier. He explained the situation and being such a high valued customer, he was allowed to pay back Salt Works II. However, he waited patiently for the police to come.

Blood Lab Findings

We students were handed out blood-typing kits to determine how different types of blood reacted with different serums. This kit comprised of simulation AB, A, B, and O blood with simulation antigen A and B serums. My group tested each blood type with both serums and we recorded the results.

AB: Formed precipitate with both antigen-A and antigen-B serums
A: Formed a precipitate with only antigen-A serum, no reaction with antigen-B serum
B: Formed a precipitate with only antigen-B serum, no reaction with antigen-A serum
O: Formed no precipitate with either antigen-A or antigen-B serum

Positive and Negative Blood Types

Positive and Negative blood types are determined whether or not they contain the Rhesus Factor. Positive blood types contain this factor while negative blood types don't. Rh+ blood types contain Rh antibodies in the blood stream while Rh- blood types don't. This is important during a woman's pregnancy for she wants to have the same Rh factor as her baby or else horrible consequences may happen.

Blood Transfusions

In modern day, blood transfusions are needed for those who have been in horrific accidents, suffer from a certain disease, or are going through surgery. Certain types of blood are required for each patient and tests are regularly performed on all imported blood. Viruses such as HIV, Hepatitis, and Malaria that are carried through the blood must not be able to reach the blood stock. Due to strict procedures blood transfusion goes through, wrong blood types hardly occur except in rare cases. If blood is transmitted into a patient but his blood is not compatible with the donated blood, there is a slim chance a life threatening reaction may occur. However, the odds of a blood transfusion gone wrong are in the thousands, but I would like to see that number reach as close to zero as possible.
