Items of Evidentiary Value In the beginning, (point of entry) the door was locked from the inside and the suspect did not have a key to the apartment. The castings from the scratches on the door could determine what type of tool was used. As you walk into the first room, which was the living room, the victim’s wallet is located in the middle of the floor. In the kitchen floor, there are blood drops, which indicate a sign of struggle. Also, there is a knife on the floor. The flashlight on counter contains a fingerprint and blood residue. The fingerprint on the flashlight would be able to confirm it was used by the suspect for self-defense. In the bedroom, at the end of the bed there is a bloody footprint on the rug. There are also blood spots
The blood, hair, and shoe print found at the crime scene were all Anna’s, making it very unlikely someone was there with her when she died. Also, at the scene there was no signs of struggle such as bloody handprints on furniture, or blood trails which would make it less likely to be a homicide. I believe Anna accidentally died by falling down and hitting her head on the table since the table was 41cm tall and had blood on it. The blood spatters on the floor were 10mm, which is the size they make when dropped from 40cm. Once Anna hit the floor, I believe she passed out due to the lack of blood and impact of hitting the floor, later dying of blood loss. I came to this conclusion because accidental is the most reasonable manner of death. There is no struggle, and almost all of the evidence was related to Anna. Also, the table being the cause of her death makes a lot of sense. There is blood on the table and the blood drops fell from the same height as the
The crime occurred inside the residents of 28 S. Daisy Avenue Apartment A, on the living room couch. The apartment complex has a common walkway which is located on the south side of the complex. Chuldzhyan’s apartment has a private court yard which is on the south side of the property.
The knife that served as the murder weapon was sourced from the kitchen. Their bodies, which were burnt quite badly, were found in their bedroom, which was upstairs. This crime scene was uncovered by fire officers who responded to a 000 call by a neighbor at approximately 3:34am, after Jeffrey had told him his parents and his brother were dead. At this point, Jeffrey creates his alibi that his brother Christopher is responsible for the murder of their parents and setting the bodies on fire, but it was he who murdered
I took pictures of all of the blood stains and collected the knife and fork as evidence.
Police haven't named a suspect, but they do have an unreleased video of a man wearing dark clothes entering the victim's apartment. The suspect may have exited through a window. Police think the victim may have known his killer as there were no signs of forced entry.
took his fingerprints and see if they matched up to the knifes and since it
We were presented with many facts that all pointed to Mr. Washburn as the murder. In the house all of the entrances were thoroughly inspected by authorities, and they found no sign of ransacking. “[They] examined all the locking mechanisms, all the doors and windows. In [their] opinion there was no evidence of any forced entry” (P.81). When police looked for fingerprints, “They were all of the Washburn family and the maid” (P.81). There was no trace of an outside party; somebody usually in the Washburn house committed the murder. While in the living room, an officer found a drop of blood. The evidence technician was called the next night to run some tests. “He sprayed the living room carpet with luminol. It is a luminous spray, and when it comes in contact with blood it illuminates” (P.82). To both men’s surprise the whole living room was illuminating. After spraying further the men found a trail from the living room through the kitchen to the garage. In the closet the men found a wet mop, which was tested for blood and also came back positive. Somebody tried to clean his or her bloody mess, and try to save himself. The physical evidence proves the killer was somebody who was familiar to the Washburn household.
...me scene, by recreating the scene using the blood direction a bloodstain patterns. Bloodstain pattern analysis use biology, chemistry, math, and physics to solve a crime. In doing research on this topic there is a lot of detail to go into this topic, so in suggestion this paper need to explain the other different investigators that process any crime scene.
A body was found with no identification was found on the body. An external examination of the body found numerous needle marks and bruising and thrombosed veins in the cubital fossae. The head showed evidence of a blunt trauma and small paint and metal fragments were removed from the wound. Analysis of the contents in the stomach found a few partially digested potato chips and some partially digested pills. A small amount of residue was extracted from the tin for analysis. Footprints were evident on the carpet where soil had been tracked in. Soil samples were collected from theses footprints. This analysis will show how Infra-red spectroscopy and Chromatography would be useful in finding both the cause of murder and possibly who the culprit was.
In the court of law, eyewitnesses are expected to present evidence based upon information they acquired visually. However, due to memory processing, presenting this information accurately is not always possible. This paper will discuss the reliability of eyewitness testimony, its use in a relevant court case, and how the reasonable person standard relates to eyewitness testimony.
Crime scenes are known to have many clues left behind. The obvious would be a the body or bodies, clothing, and sometimes even the murder weapon. While these are great way to solve a case there's another kind of evidence; trace evidence. Trace evidence are small pieces of evidence that are laying around a crime scene. There are many types of trace evidence some of them include metal filings, plastic fragments, gunshot residue, glass fragments, feathers, food stains, building materials, lubricants, fingernail scrapings, pollens and spores, cosmetics, chemicals, paper fibers and sawdust, human and animal hairs, plant and vegetable fibers, blood and other body fluids, asphalt or tar, vegetable fats and oils, dusts and other airborne particles, insulation, textile fibers, soot, soils and mineral grains, and explosive residues. Although these are the most common found elements, they are not the only ones. The Trace Evidence Unit is known to examine the largest variety of evidence types and used the biggest range of analytical methods of any unit. materials are compared with standards or knowns samples to determine whether or not they share any common characteristics. In this paper I will discuss the different kinds of trace evidence and how crime scene investigaros use it to solve cases and convict criminal.
On the night of January 13, 2013, Jeffrey Wright was killed after causing his wife, Susan Wright, years of distress and abuse. His body was disfigured after being stabbed approximately 193 times. The body lay on his former mattress which had become blood-soaked and cut up. Attached to his wrists are ties which had been used to anchor him to the bed, making him unable to escape. His last visual memory was the sight of his wife hovering over him with a knife, wondering how she had been able to do what she was about to do. How could she, his wife, betray him and kill him with no remorse?
The junk shop owner testified that there was only one knife in stock and my client had bought it which means there is more than one knife because I has the same exact knife. Also, there is reasonable doubt that the defendant did not commit the murder because there weren't any fingerprints left.
Next is the presentation of evidence. There are two types of evidence, direct and circumstantial. Direct evidence would be things like video recording of the crime. Circumstantial evidence would be something like a witness saw a man running with a gun, a ski mask, and a bag of money in hand, even though the witness didn’t see
... from the First 48 Hours. I also talked about bullets that go with firearms. Lastly robbery was covered. I went over how robbery went in the video “In Cold Blood” from the First 48 Hours. I have learned in this class that a lot of what we have covered goes into each crime scene investigation. There are lots of steps that have to be covered, and lots and lots of note taking.
