In order to apprehend a criminal the first steps involve evidence collection. CSI technicians collect blood samples either by submitting a piece of clothing or by using a sterile cloth and a small amount of distilled water to remove some blood from the body as well as collect blood samples by scraping trace blood spatter from walls and floors into a sterile container using a scalpel. Blood samples are also collected from the body. These samples are then sent to be analyzed to determine if the samples are the same since any blood at the crime scene may belong to either the victim or assailant. The lab will perform DNA analysis on the sample as well as the victim to determine whether or not it can be used later to compare to blood taken from all suspects.…

When investigating a crime scene, many different variables are taken into account such as fingerprints, any other forms of DNA, or even clues left behind at a crime scene. Even looking at blood splatter, the forensic technician can conclude an estimated guess to the weapon used, the height of the person, whether it was foul play or not, and even if it was passive patterns or projected patterns. Blood splatter analysis becomes important when recreating a crime scene (Peschel). Bloodstain pattern analysis comes into play; and that is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed (“A Simplified Guide”).…
Why do you think forensic scientists study bloodstain patterns? What can be learned from them?…
Blood samples, DNA samples, and fingerprints just may be new evidence to a better environment. Our area should have a CSI unit because it can highly benefit the economy and the people in the area. A CSI unit is a crime scene investigation unit that works with detectives, scientists, and even detectives to solve crimes in the area. The unit could help find more justice in crimes and the crime rate may even drop due to this successful group of individuals. Without the CSI unit, crimes will continue and won’t improve the economy due to all of the problems going on.…

In Being There and The Bloody Chamber the presence of genuine love, a lack of genuine love, and sexuality are all explored.…
Analyzing blood is the worst part of the job to me. It is one the main reasons why I might not pursue this specific career in Criminal Justice. I can’t deal with blood because it affects me mentally. I can talk about it, but the sight may make me nauseous or I could faint, especially if it’s a large amount (pool stains). I could sit and watch the most gruesome horror movie and eat dinner while watching it. However, I do feel I may get over that hump like if I talk about it more and the repetitive experience through the job. I searched around the web and found a few interesting facts about blood splatter analysis. I also found a video explaining blood splatter and its relation to the murder case involving a hammer in Arizona. I will post the…
When investigating, they prepare a solution of Luminol, sodium hydroxide, and hydrogen peroxide and spray it where they want to investigate. Any iron present in the blood will catalyze the chemical reaction and illuminate. This lets the investigator know the location of the blood. Even trace amounts can be located with this method. The glow that is given off lasts for about 30 seconds. This method can especially work well when the investigators are not sure whether the stains present in a room is genuine.…
