Evidence Board
The evidence below is what I found about Anna's death.
My explanation for why I think it is aspirin is because it had the same chemical reactions the the aspirin did with Indicator 1, Indicator 2, and Indicator 3.
Fingerprint Notes
A fingerprint contains a lot of characteristics. They have ridges and ridges are the lines that stick out of your fingerprints. They also have a core witch is the middle where all the details begin. there is also the delta where three areas converge. It also has an arch, loop, and a whorl. It may also include some ridge endings witch is a short ridge line, a bifurcation is when one line becomes two, and a dot where is just a plain dot.
How to take LATENT prints
The way to take a LATENT print is to dust a black powder over a fingerprint and cover it with tape and the print will show up and you will have it for evidence.
When I examined the finger print I found out that it was Alex Garcia because he has the same minutiae as the finger print that was found at the scene.
Hair and fibers Notes
The difference between fiber and hair is fiber is uniform and irregular types hair is irregular. The main parts of a hair is a cuticle and a medulla. A medulla is the line found inside the hair follicle. A cuticle is the lines found outside of the follicle. The cuticle can be found in 3 different types of ways coronal, spinous, and imbricate.
The way I found out whos hair was found at the crime scene between the suspect was Anna's Garcia because it hade the same cuticle and also have the same missing medulla.
Whos Footprint was Found at the crime Scene?
I Have come to the conclusion that the footprint found at the crime scene is Anna's because the design on the print was the same as the one found on Anna's shoe.
Whos blood was it?
The blood that was found at the crime scene is probably Alex's or Anna's because they where both B+ which is the same type of blood found at the crime scene . It could either be Anna or Alex.
The Blood Spatter Lab
PBS: The Effect of Height on the Diameter of blood spatter Evidence at a Crime Scene
The purpose to this lab is to determine the diameter of the blood spatter from the height it falls from. The blood spatter that is found at a crime scene is to find out how the victim died and what weapon was used. My hypothesis is if I were to drop blood from an increasing height, the blood drop diameter would get smaller. The case relates to the lab because we are trying to figure the diameter of the blood drop from the height it came from.

The things you will need to complete this lab:
- Blood
- Pipette
- Meter stick
- Piece of paper
- Chart to graph the
The hypothesis that I had thought was wrong. The higher the blood drop is the bigger it gets. I have learned how to measure diameter. I have also learned and how to figure out what happened to Anna.
What is DNA?
DNA is made up of nucleotides which contain sugar, phosphate, and nitrogen base. It also has a backbone that's made up of phosphate and deoxyribose. It also has a ladder made up of thymines, adenines, guanines, and cytosines. DNA controls the production of proteins within the cell. The proteins control all chemical processes within a cell. Your DNA make you unique. It makes you look like you and your skin the skin tone and type it is. DNA can determine who is your parents, who killed someone, and weather you are somebodies sibling.
Nucleotide:
A nucleotide is made up of a base pair, deoxyribose, and phosphate.
DNA Gel Electrophoresis/DNA Profiling:
DNA Profiling is when you only need a little bit of DNA to find out who the persons DNA belongs to. Scientist can also make copies of the little DNA that was given through a process called Polymerase Chain Reaction (PCR). PCR is used mostly at a crime scene so if there is DNA left at the crime scene. There is also a process called Gel Electrophoresis that can separate DNA so that you can compare a person's DNA with another persons DNA. All these diferent types of methods are great I would use any of these. They are all great ways to find DNA from a crime scene, you can find out who your parents are, you can find the criminal, and you can find whose blood is whose, because for example Anna and Alex have the same blood type but by doing all these steps we have found that is Anna's blood.
Was It A Crime?

Per.2
The case that we have been studying is the case of Anna Garcia. She was found dead in her house at 9:56 a.m. . She was last seen the morning before at 6:30 a.m. walking her dog. The person who called the police is the neighbor who heard the dog bark for 2 hours. before calling the police. He had noticed that she was wearing a jacket even though they were experiencing a heat wave. She was found facedown and on the floor next a lot of relevant evidence.
Found next to Anna's body were fingerprints. Fingerprints are used when found at a crime scene to help identify the potential suspect or if it is the victims fingerprints. This method has been used to solve crimes since the 19th century. Fingerprints are the little lines found on the tips of your finger. When they are found the detectives dust it them they put tape on it and collect the little details that was found on the fingerprint which are the little details like dots, bifurcations, bridge, fork, ending ridge, hook, eye, double fork, delta, and a triple fork. These little details are called minutiae. The fingerprints found at the crime scene were Alex's which was her soon to be ex-husband.
The other procedure we did in this case was blood typing. Blood typing is figuring out what type of protein's and which type of blood a person is. There is four types of blood you can have:
~type A ~type AB
~type B ~type O
These types of blood is determined when you mix your blood with antibodies against type a and b then they also figure out what your RH is which determines whether your positive or negative. When getting the blood we determined that it was B+ which was the same as Alex's and Anna's.
Footprints were also found at the scene. Shoeprints can determine who's shoe was it and if it was the victim or the suspect. The way you figure out who's shoeprint was who's is by just comparing the shoes to the shoeprints. The shoeprints that were found at the crime scene were Anna's.
Hair was found at the crime scene as well. The way you can make an inference on who's hair was it is by finding the difference between if its and animal, human, or fibers and the way you can determine which is which is by the texture of the hair. The most important thing is telling whether who's hair is it. You can look at the medulla and you will know who's hair it is. The medulla is the line that is found inside the strand of hair. The cuticle is part of this as well. The cuticle is the outside of the strands. The hair that was found at the scene was Anna's.
The pills found on the table were found at the crime scene too. The way you can determine what is what is by mixing chemicals with other things along with the unknown substance to see what has the same effects so you can know what it is. The pills were found to be aspirin (acetlylsalicylic acid).
Blood spatter was also found at the crime scene. You can take the blood spatter and know where it came from. The higher it came from the bigger the spatter gets. You can use blood spatter to determine what weapon was used. The blood spatter found was coming from Anna's head.
DNA analyzing was also done on the case. Alex and Anna had the same blood type. The detectives preformed a process called Gel Electrophoresis. Its when DNA (with a negative charge) goes to the positive side of the gel. The small strands moved faster but the log ones went slower. In this case we found that it was Anna's blood that was found.
By what we have collected from the evidence and the information that was given to us I have made a conclusion of what has happened to Anna. Since she had diabetes and that he stomach was swollen I think she was pregnant she passed out after coming home from her walk and hit her head on her way down and bled out of from her head. The only problems though is that she could have been bloated, and I don't have a sufficient amount of evidence to back this up. If I were an investigator I would not have made this final conclusion for her death because there isn't enough evidence and we don't know what is wrong with her internally. We have pretty much found what we could with he labs we have done.
In conclusion Anna was found dead in her house at 9:56 a.m. The person that called the police was the neighbor. Alex was the last person to see her the night before she died. Her death was accidental because since she had diabetes her blood pressure was possibly low when she got back from walking her dog, her stomach was bloated so she was probably pregnant so she was probably out of breath too so when she went to go use her medicine and passed out and on her way down she hit her head on the table got up walked around and bled to death from her head.
When her death is finalized the investigators should look back at the evidence very carefully to actually finalize her death. Its important for them to do this so if the go back and find something it can change the whole investigation. Anna had a lot of people that had a motive to kill her they could have made it look like an accident for them to get away from it.
It all depends what else information we get for them to proceed in the investigation. Unless it has a murder that there really isn't anywhere else to go because if it was natural, suicide, or an accident there isn't a person you need to convict. Until further information there isn't anything to further investigate form the conclusion I have come to.
