The blood found at the crime scene matches Erica Piedmont and
Anna Garcia’s blood type. I know this by blood analyst. To determine what blood
type the blood was I had to test it. In testing the blood I checked for blood
type A, B, AB, and O. I did this by placing two drops of simulated blood in the A and the B wells of a clean blood
typing slide. Then I had to mix the two together and wait to see if the antegens in well a attacked the a antibodies or if the antengens in well b attacked the B antibodies. For if the If there was clumping then depending on which well (A or B) determines
the blood type. In this case the blood from the crime scene was B and Anna Garcia
was B as well. In my conclusion I determined that the blood found at
the crime scene was Anna Garcia based on the results.

According to the data above the unknown substance is asprin. I used 3 test to decide what the unknown was. the texture of the substance was clumpy and bulky. The asprin and unknown are alike. The reaction was the same from the unknown and the asprin. This tells me that the unknown substance was asprin.

The pictures above are showing all persons of interest hair. I was looking for the hair that matched the hair at the crime scene. The hair at the crime scene has a medulla (a darkened spot on the strand of hair) and looking for a cortex that is similar. Lucy Leffingwell hair is red and no similarities. Erica piedmont has a look of similarities but no definite medulla. Doug Greene had a brownish tent no light spots like the hair. Alex Garcia has medulla but a dark outer layer of hair. Erica Piedmont has a bunch of similarities darker spots and lighter spots but not the same places or the right tents. Last is Anna Garcia. Anna has a medulla and all the right light and dark spots in the right places. In my evidence collected I believe that the hair belongs to Anna Garcia.
Shoe print from crime scene
Anna Garcia
Erica piedmont
Doug Greene
Alex Garcia
Lucy Leffingwell
The shoe print from the crime scene has a V shape pattern. If you look at the shoe print you can illimate Erica Piedmont because the ridges on the shoes do not match in anyway they have small like long v ridges. Doug shoes pattern on the bottom are do not have a V like pattern like it is more of an box shape. Alex Garcias shoe has the long V shape as well but the shoe from the scene is short V shapes. Lucy Leffingwell Has rectangle and little ridges not a V. I believe that the shoe print from the crime scene is annas based on the short V ridges in the print and the bottom of the shoe.
The Finger print at the crime scene is Alex Garcia's. His print matches the exact one at the scene. This is decided by 12 details in the fingerprints that match. This makes it to were I am positive on whose it is. The comparisons are highlighted in the above picture. These tell me that the print is Alex's print.
According to the glaister equation anna died around 7:00 am.
height graph
the diamameter of the blood would be around 19 mm at the of 5'4. My data is approxametly around the same.
