Blood #2 found at scene belonged to the victim
2. Thus blood #1 found at scene belongs to the suspect
3. After analyzing the suspects, Kyle's blood matched the blood found at the scene and due to all the other evidence (from the other sections of the lab) we were able to conclude that that perpetrator was Kyle.
Hair Evidence -- The only hair was that of the victim, no other matches were made or are relevant.
Processessing of Evidence
Fingerprints -- There were none taken at the scene, but dusting and tape lifting would have been used if there had been evidence; then compared for ridge patters of suspects or database.
Hair -- if root was attached, DNA using PCR technology; if not, microscopic examination and 15-20 representative samples to compare.
Blood -- RFLP, DNA Analysis, Precipitin test, comparative analysis
Footprints -- precise measurements and castings, comparison to suspects or national database for information
Drugs -- spectrographic or chemical analysis, depending on type and substance (powder, liquid, solid, etc.) (Schiro, 2010).
Suspect List and Exclusion, Inclusion -- The officers found only four boys at the scene, identified previously as Stan Marsh, Kyle Broflovski, Eric Cartman, and Kenny McCormick. The boys ran from the scene, but warrants were secured to take hair, blood, and shoe prints from all four. The results were thus:

Crime Scene Recreation -- It would be quite easy to say, based on the physical evidence, that Kyle was the murderer in this case. However, we must not...
All interviews share one thing in common -- that the boys were almost inseparable in their pranks and activities, with Kenny often being the brunt of their jokes and misdeeds. When investigators interviewed all suspects separately, each incriminated another part of the group. This suggests that instead, this may have been a group activity. Kyle may be, at times, the ringleader of the group, certainly he was the one who first pointed to his friends and said, "they killed Kenny."
In fact, based on interviews, we believe that the entire event was not necessarily a planned or premeditated murder, but a childish prank gone wrong. It turns out that Cartman's grandfather recently returned from a trip abroad, and brought Cartman's father a collectible sword, knowing his passion for antique weapons. His father hung the sword in his den, but the item went missing on the afternoon of the 8th of November. Cartman likely brought the sword to his afterschool play time, and the group decided they would have an old-fashioned sword fight. Kenny, being the smallest, was teased and tormented, and, in a fit of pique, Kyle held him up to the wall and called on one of the others to "hang this balckard by the post, mateys," emulating the pirate game they were playing. This puts Kyle's footprints and blood spatter residue conclusive with the evidence, and also the proximity to the victim when officer's arrived. Because it was rather cold in South Park, the boy's all had gloves on, making fingerprinting impossible. Subsequent interrogation confirmed the game, and Kyle's holding of Kenny. It remains unclear which other person was directly involved.

Crime Scene Investigations: Many crime scene investigations revolved around safeguarding the crime scenes, protecting physical evidence, and gathering and transferring the evidence for scientific evaluation. This process is based on the role that physical evidence plays in the overall investigation and determination of a suspected criminal activity. Notably, the ability for physical evidence to play its role in the overall investigation process is dependent on actions that are taken early enough
4-8). While these standard procedure are relevant in the preservation of any crime scene, certain specifications exist when dealing with the unique challenges associated with the different types of crime scenes including homicides, rapes, arson, and nighttime crime scenes. For instance, in the case of homicide, as well as the aforementioned steps, the area must be preserved for trace evidence such as fingerprints. In the case of rapes or sexual

Upon arrival at the crime scene as a crime scene investigator at 3a.m, I found the deceased victim with an obvious gunshot wound in the chest as the first officer informed me of the present witnesses.

Crime Scene Investigation: Homicide and Its Psychological Effects Crime scene investigation is often a challenging and difficult line of work for even the most experienced law enforcement agent. There are some crimes that are more difficult to handle spiritually and emotionally than others. Crimes against children and the elderly are often most difficult to excuse and most difficult for crime scene investigators to process psychologically (Swanson, Chamelin & Territo, 1999: 313).
Crime scene investigation is a field with rapidly changing tools that seem to evolve almost every day as a result of the changes made in technology. However, even the simplest elements of a crime scene can still inform investigators an epic amount. For instance, in this case, the position of the body and the weapon used represent the main forms of evidence and can help investigators uncover the elements which motivated
