Introduction- head. Next to her was a fallen desk

On August fourteenth in Anytown, USA, Anna
Garcia, a thirty-eight-year-old Hispanic
woman, was discovered dead in her home at
9:56 A.M. A
neighbor of Anna called the police due to her unresponsive behavior and her
dog’s unusual loud barking. Anna’s neighbor reported that he had last spoken to Anna the previous
morning at 6:30 A.M. when she was walking her dog. He also mentioned that she
was wearing a sweater during a heat wave. The
police and the EMT arrived at the scene
at 9:56 A.M. They found Anna lying face down in the entry hallway of her 73?F
house. The EMT established that she was dead. The
police identified four possible suspects of the crime: Alex Garcia, Lucy
Leffingwell, Doug Greene, and Erica Piedmont. The
police immediately notified the CSI and medical examiners to determine the
cause and type of Anna’s unusual death.

            Summary of
Findings- In the front entry hallway,
the investigation team found Anna Garcia lying face down with a pool of blood
under her head. Next to her was a fallen desk
and on the floor, were multiple blood splatters. Shoeprints, vomit, hair, pills,
a syringe, juice, a bottle, etc. were also evident at the crime scene.
Through the fingerprint analysis, we examined
the minutiae and ridge patterns of each person of interest. The fingerprint
pattern and minutiae at the crime scene matched Alex Garcia’s fingerprint pattern
and minutiae (radial loop/12 minutiae). Through the shoeprint analysis, we
compared the shoeprint recovered from the crime scene to the shoeprints of the
persons of interest. As we compared each person’s shoeprint, we discovered that
the shoeprint at the crime scene belonged to Anna, because her shoeprint
pattern was very similar to the shoeprint pattern recovered from the crime
scene. The investigation team collected blood samples from the crime
scene and we compared them to the persons of interest. We found out that Anna
or Alex’s blood was at the scene by conducting blood clumping tests. The
limitation in using this type of analysis was
that several persons of interests could have the same blood type which would’ve rendered
the method of analysis useless. Through the
unknown substance analysis, we took the unknown substance
(pills) and separated them into five different substances. We then used
three different indicators, mixed them with
different substances, and observed the chemical reactions. We compared the
reactions of the known substances to the unknown substances. The aspirin and
the unknown substances had the same chemical reactions. Therefore, the unknown substance
in the crime scene was aspirin. There were quite a few limitations in
finding the unknown substances. Some substances could
have had similar/identical appearances, textures, and chemical properties which
would’ve prevented us from finding the unknown substance. There were also
several external factors that could’ve changed the reaction between the
indicators and substances, leading to inconsistent data. To find the height in
which Anna fell, we conducted an experiment to find the effects of height on blood
splatter diameter. We dropped the blood at fifteen-centimeter intervals and found
that the increase in the amount of height didn’t affect the diameter of the
blood much. After we analyzed the data, we determined that Anna fell
approximately 90-95 cm since the diameter of the blood was 10-15 mm. A major
limitation of this experiment was the amount incorrect results caused by small mistakes
in the procedure
