In this case analysis, Molly Wright was murdered on 27th Sept 2006, at Redhill Gardens, Airedale, Castleford in the United Kingdom. Bloodstain Pattern Expert Samantha Warna is correct in her testimony. She testifies that the victim, Molly Wright, was killed by her son in law and business partner, David Hill. If she said that she found blood stain patterns on his shoes, jeans, and the denim jacket that he was wearing at the time of her murder (Casey, 2012). She said that the distribution and condition of her blood was consistent with repeated blows from a heavy object. She was struck fifteen times in the head left with a pool of blood on the floor. Blood was found all over the living room and the kitchen and her hands appeared to
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.
Cynthia Adae was taken to Clinton Memorial Hospital on June 28, 2006. She was taken to the hospital with back and chest pain. A doctor concluded that she was at high risk for acute coronary syndrome. She was transferred to the Clinton Memorial hospital emergency room. She reported to have pain for two or three weeks and that the pain started in her back or her chest. The pain sometimes increased with heavy breathing and sometimes radiated down her left arm. Cynthia said she had a high fever of 103 to 104 degrees. When she was in the emergency room her temperature was 99.3, she had a heart rate of 140, but her blood
When conducting research for my project, I came across a website that contained a few primary sources regarding the Salem Witch Trials. One of these primary sources was the photo of a legal document explaining the death warrant and reasons for execution of a woman named Bridget Bishop. Bishop was claimed to be a witch in Salem during the year 1692, and the document explaining her significance involving witchcraft resides in the Peabody Essex Museum in Salem, Massachusetts. My thesis for this primary source is that the judge and jury believed they were seeking justice by executing Bishop, a woman whose death was truthfully based on her differences as a person rather than actual crimes she committed.
The court’s decision based on the treatment of young people in this case emphasizes on the concept of social justice, which means the fair allocation of wealth, resources and opportunity between members in a society. The appellant in this case, Louise Gosselin, was unemployed and under the age of 30. She challenged the Quebec Social Aid Act of 1984 on the basis that it violated section 7 of her security rights, section 15 of her equality rights in the Canadian Charter of Rights and Freedoms and section 45 of the Quebec Charter of Human Rights and Freedoms. For the purpose of this essay, we shall explore the jurisprudence analysis of section 7 and section 15 of the Canadian Charter of Rights and Freedoms. Section 7 states that everyone has the
Now that I found a motive to as why David Hill would have killed Molly Wright and she was about to lose their company. David still denied murdering Molly after the information was out about the debt she caused the business. Technicians found blood located in the kitchen and living room Pathologist stated the attack took several minutes, going by the marks and the distance of the blood that indicated the distance. The piece of evidence that was found was from David Wright’s clothes and shoes is the most critical piece of evidence and that was the blood splatter. The blood splatter places David Hill at the scene of the crime at the time of Molly Wright’s murder.
On May 21, 1980, Katherine Reitz Brow was stabbed over 30 times in her Ayer, Massachusetts home. There were bloodstains throughout the house and her purse, some jewelry and an envelope where she had been known to keep cash was missing. Investigators found hair, blood ladened fingerprints on the toaster and the kitchen faucet which was left running. A bloody paring knife which was perceived to be the murder weapon was found in the waste basket. Mr. Water’s became a suspect because he lived next to the victim with his girlfriend, Brenda Marsh. He also worked at a local diner that Ms. Brow frequented and employee’s revealed that she had been known to keep large amounts of cash in her home.
Ashley Smith was a young girl that was placed in a juvenile detention centre at age 15 for throwing apples at a mail man. Her short sentence quickly extended into a life sentence because of so many infractions within the prison system. Ashley suffered from extreme mental health issues and was place in a psychiatric prison facility, however this facility was shown in the documentary to be corrupt and their actions with Ashley were extremely illegal. Furthermore, Ashley wasn’t given the proper help and treatment that she needed, instead she was physically and verbally abused by guards in the prison, and she ultimately passed away in the prison. Her death is still being debated about whether
On December 15, 2005, Minnie Smith was found dead in the home she shared with her husband, Marvin Smith. Smith was charged with first-degree murder for the death of his wife. At the end of the trial, the prosecution asked for and received an aiding-and-abetting instruction, which would allow the jury to convict Smith even if they found that he had not delivered the fatal blow. The jury convicted Smith but did not specify which theory of guilt they adopted. The California Court of Appeal affirmed the conviction and rejected Smith’s argument that he had not been given adequate notice of the possibility of the aiding-and-abetting instruction. The California Supreme Court denied Smith’s petition for review.
It was a 92 degree fahrenheit morning at 9:45 on August 14th, when Doug Greene placed a call to 911. He informed the police that he was concerned because Anna had been seen wearing a sweater the previous day despite the unusual heat and wasn’t answering her calls or her door. Both the police and the EMT arrived at the crime scene at 9:56 am where they found Anna Garcia lying on the floor. They entered the crime scene and declared Anna dead. The crime scene was then secured at 10:20 am for investigation. The crime scene was confined to a 10’ by 20’ entry hallway. At the crime scene, investigators marked areas where vomit, blood stains, blood spatter, footprints, a strand of hair, scattered pills, a syringe, and dirty cup were lying on the floor. They also discovered fingerprints that could be taken to a lab for analyzation. Anna was found lying face-down against the floor surrounded by blood and vomit near her mouth. The table in the crime scene

Three items found in Stafford’s car: a blanket, a red and black sports bag and a CHUX cloth were found to have the same blood type as the deceased on them. This blood type is uncommon and only shared by 0.00005% of the population.
Bloodstain pattern analysis (BPA) is one of many specialties in the field of forensic science; the science of bloodstain pattern analysis use scientific knowledge from other fields to solve problems. BPA also uses the scientific method to examine bloodstain evidence at a crime scene where blood is present by gathering information, observing, documenting, analyzing, evaluating, and technical or peer reviewing. A bloodstain pattern analysis job is to collect, categorize and interpret the shape and distribution of bloodstains within a crime scene (Peschel, 2011). Bloodstain patterns can reconstruct a crime scene and then determine the crime as an accident, homicide, or suicide; the blood can also identify the location, quality and intensity of an external force. The purpose of a BPA’s is to determine bloodstain patterns and to recreate the action that caused the blood.
Blood stains are one type of evidence that can be found at a crime scene. Blood that is still in the liquid form should be picked up on a gauze pad. Once the blood is dried thoroughly it should be refrigerated and sent to the Laboratory (Andrus et al., n.d., para. 1). If the blood stain is found dried on clothing, the officer should wrap the piece of clothing in clean paper and place it in a sealed and labeled container. An object with dried blood stains needs to be sent to the Laboratory if it is small enough. If the object is too large to send, then using a clean knife the stain needs to be scraped onto a clean piece of paper, which then can be folded and placed in an envelope (Andrus et al., n.d., para. 2). When collecting autopsy blood samples, the officer should request that the pathologist obtain the sample directly from the heart and place it in a yellow or purple stoppered vacutainer. If the victim is still alive but in serious need of a blood transfusion, then the pre-transfusion blood sample needs to be obtained promptly before the hospital discards it (Andrus et al., n.d., para. 4). It is important for the Laboratory to receive all blood samples within 48 ho...
Many of us enjoy watching crime scene investigation shows, but in the criminal justice system forensic investigation is an essential field that requires upright observations and a prodigious interpretation. Under forensics, it is difficult to blame someone without scientific data. For that reason, Larry K. Gaines author of the textbook Criminal Justice in Action explains the importance of Blood Spatter Analysis. Specialist can learn a great deal about violent crime by examining where blood landed at the scene, the size and consistency of drops, and the pattern of blood spatter (Gaines, 2011). Consequently, an article of the Blood Spatter Analysis will be used to explain the research methodology the author uses to proceed certain investigations.
Since blood evidence connect with a crime that can give info, might perhaps crack the case, it is necessary to properly record, collect, and preserve this form of evidence. Blood evidence that is handled improperly can diminish or ruin a possible source of details in a case. Blood evidence that is correctly collected and preserved can determine a strong connection among a person and a criminal act. Blood evidence or the dearth of blood evidence can also be used to strengthen or negate an eyewitness account or any accounts that the suspect might make. Blood evidence can also direct the investigator the path that he/she must go to solve the case. If blood evidence is recorded, collected, and stowed properly, it can be given to an arbitrator or jury a couple years from the time of the criminal act. Maybe the most influential request of blood evidence is the aptitude to completely remove an individual as a possible suspect in a crime. Effective communication is the threshold in processing blood evidence. Open and precise communication has to happen among a uniform officer who first re...
