Lowry police asked my laboratory group and I to investigate the remaining human skull and blood samples found at a crime scene in an abandoned building in Lowry. The investigators found two types of blood samples from the crime scene, one that is B-, which appears to be from the victim and the other sample O+ is believed to be from the criminal. The police provided four blood samples from their potential suspect list, and also provided the medical records of a missing teenager who blood type is B-. In order to continue our investigation, we needed to review the essentials concepts of blood types and human skeleton. According to The Royal Society of Medicine Health Encyclopedia (2000), a reliable source that presents crucial medical concepts,

In accordance to Walker-Pacheco (2010), author of our laboratory book, sex encompasses biological characteristics that determine if a person is male or female. On the other hand, ancestry is the geographical location where your ancestors come from. Some characteristic of a European descent male will vary from an African descent female and an Asian descent male. According to Walker- Pacheco (2010), author of our laboratory book, the most influential characteristics that help determine sex are: overall skull size, shape of forehead, supraorbital ridge, mastoid process, orbital shape, nuchal area and occipital protuberance and chin shape. In the same way, the most significant characteristics that help determine ancestry are: nasal root, lower border of nasal aperture, orbital shape, malar tubercle, dental shape, lingual side of incisors. Based on this information our group hypothesized that through the blood analysis and the information provided by the police, we would be able to identify the potential perpetrator. In the same way, our group hypothesized that though forensic analysis, we would determine if the information collected of specimen #301 matches the missing person characteristics.
Methodology
For the blood work analysis
Materials:
• One plastic piece with three identified wells (A, B, Rh)
• One pair of gloves
• Three different colored (blue, yellow and white) toothpicks
• Four different types of blood samples, synthetic anti-A, Anti-B, Anti-Rh serum
• Paper and
