Blood Stain Analysis Midterm
Bloodstain Pattern Analysis Midterm

ABSTRACT:
This is the midterm scenario in which we were told to describe what we think happened here. Due to the lack of information associated with the crime scene and information on the length, width and depth of the bloodstains it was very difficult to analyze. I think I may have figured out what happened. The victim Ms. Williamson was attacked in her kitchen, but the murder took place about ten to fifteen feet from the front door parallel to the table where the body was found. The perpetrator was attempted to clean up the crime scene, though unsuccessfully.
Blood Stain Pattern Analysis Midterm When you first look at the crime scene, it looks as though the victim may have been doing dishes. This explains the broken dishes found on the kitchen floor. Since there is no noted damage to the front door, it is likely that the perpetrator knew the victim, and he/she knocked at the door. The keys thrown to the side is very odd and makes me think that the victim was frightened and tried to keep the perpetrator out of her house, when he/she was able to finally push his/her way in the victim ran to the kitchen. This is where the first of the injuries occur. The dishes were likely used to fend off the attacker, and when that did not work, the victim pulled a knife from her knife block. She in an attempt to protect herself, attempted to use the knife on the perpetrator. He over powered her, and took the knife from her. It is possible that blood B is a drip trail from the perpetrator, which he got from the struggle for the knife. A Drip trail is a pattern of spatter that is deposited on a surface from one point to another. A drip trail is a bloodstain pattern that is typically consistent in both size and shape (Bevel & Gardner, 2008). A drip trail bloodstain pattern can range in size from 3 to 25

    Pictures with measuring markers were taken to show the position of the tool mark and for comparison. Liquid silicone was utilized to make an impression of the tools used on the door. During taking the impressions, I could see the smallest bit of blue fiber hanging from a piece of wood on the door frame. I removed the fiber tapping the sticky side of a post-it to the fiber. I then folded the post-it, labeled it and placed in an manila envelop for evidence. Walking a little further into the domain, you could see what caused the sound of glass breaking, a vase that appeared to be knocked over during the home invasion. The living room was in disarray with couch cushions taken out of the couch, papers on the floor and drawers pulled out of desk. On the desk was a smudge of a latent partial print that I retrieved using black powder and sticky tape. As the victim stated in her report to the officers, I went up to the bedroom to discover the missing jewelry from the jewelry box. Once again latent fingerprints were found on the desk where the Apple computer and jewelry were taken, so again prints were taken off the desk with black powder and placed on sticky tape for evidence. After thorough investigation of the house, I exited the domain to head back to the…

    Furious, I rip months of work off my apartment wall. The yellowing paint comes off as I fling the paper across the room. I’d been on this case for so long, and yet, I was still at square one. I pace the small room trying to figure out what I was missing. There was one piece of the puzzle that just didn’t fit. I walk over to the small desk and scan through the police files. The killer used the same M.O. but nothing connected the victims.…

    As I pull up to the crime scene as the first responder, I would check to make sure there are no other people in a life threatening state as that would be the only reason why I would not secure the crime scene right away. After determining no one in critical condition, I would tape off and secure an adequate amount of space around the scene. I would first collect the bloodstains and place them in a plastic bag to keep them from molding. Then I would move to the personal belongings of the victim. I would collect them in separate bags to avoid contaminating any evidence if there is any different DNA on the different items. I would also collect the beer bottle in a separate bag and send it out for any kind of DNA testing such as saliva or fingerprints. Next I would move to the foot prints and tire tracks as I would take multiple pictures of them with something such as a…

    Customer C’s silverware is on the left side of his plate, which we concluded he was left handed. The handprint on the wall shows and right handed print, which mean the shooter was holding the gun with his left hand when he shot. Letter Y’s footprints lead towards the back of the counter, which would mean those would be Ernie (the owner’s foot prints). Letter X footprints come from the direction of the barstools leading towards the print on the wall. Ernie said that the murder leaned his hand on the wall while firing the gun, so since the footprints of X follow the way the person who put their hand on the wall is standing, X belongs to the murderer.…

    Since the creation of religion, there has always been a debate to whether or not religion is the main cause of conflicts throughout history. In Karen Armstrong’s book “Fields of Blood”, she argues that people use religion as an excuse for the cause of wars and ignore all other aspects. Karen Armstrong is correct. Throughout history, there were many wars and conflicts that weren’t caused by religion yet many leaders used the blame of religion to their advantage to conceal their true intentions. Wars using religion as a cover up for power is shown in the expansion of the Islamic Empire and in ISIS, while motivation from religion opposes Armstrong’s idea.…

    Analyzing Blood

    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…

    Blood Batter Analysis

    Blood spatter analysis began in 1895 with Dr. Eduard Piotrowski, who published Concerning the Origin, Shape, Direction and Distribution of the Bloodstains Following Head Wounds Caused by Blows, which was the first major study of blood spatter in history. Piotrowski’s research influenced the work of other European scientists throughout the twentieth century, such as Dr. Victor Balthazard, who further investigated blood spatter. Dr. Balthazard was a French scientist who expanded upon Piotrowski’s research in investigating the patterns, impacts, and trajectories of bloodstains and, in 1939, presented his research to the 22nd Congress of Forensic Medicine. Furthermore, in England during the 1940s, Dr. Francis Camps investigated many criminal cases through the analysis of blood spatter, including the 1949 murder of Stanley Setty in…
