The evidence at the crime scene has been analyzed and the findings were reported. Fingerprints found at the crime scene were found to be Alex’s. A plain arch, tented arch, whorl, or radial loop fingerprint was identified in each suspects fingerprint, Anna’s fingerprint and the fingerprint found at the crime scene. After comparing the fingerprints based on these characteristics, it was confirmed that the fingerprint found at the crime scene matched …show more content…
When ABO grouping was performed, the blood clumped when mixed with antibodies against type B blood. All of the suspect’s blood along with Anna’s was mixed with the antibodies but only Anna’s and Alex’s blood was found to be type B . In a blood spatter lab, it was concluded that the droplets of blood at the crime scene fell at a 90 degree angle from roughly the height of a person bending over. This was tested by dropping droplets of blood from varying heights using pipettes and micropipettes. Multiple trials were run for the most accurate results and great care was taken to ensure credibility. After analyzing the results to this experiment, it was agreed that the blood droplets at the crime scene fell from roughly three feet high. Furthermore, the drops were circular which led the experimenters to believe that they fell from a 90 degree angle. Additionally, the droplets were patterned in a line next to Anna’s head. Along with the matching blood types, an observation was made that the droplets of blood led to a pool of blood around Anna’s head and which solidifies the evidence that the blood found is
