On August 14, 2017 emergency dispatchers received a call to the house of Anna Garcia from her neighbor who says that she never opened the door when he went to check on her yet her dog has been barking for 2 hours. At 9:56 am the police and the EMT arrived at the scene and found her lying face down in the entry to her house. She was pronounced dead at the scene. Anna’s house temperature was 73 degrees Fahrenheit, and the temperature outside was 92 degrees Fahrenheit yet she was found wearing a sweatshirt. Surrounding Anna was muddy footprints, a knocked over lamp that contained a hair, three unidentified pills, an empty glass that contained fingerprints, a syringe, a knocked over coffee table with a blood trail leading to the floor, a trail …show more content…
After the analyzing was complete the print found at the crime scene was determined to have a loop ridge pattern. To other figure prints, Alex Garcia’s and Lucy Leffingwell, were also identified as having a loop ridge pattern. The investigation then turned to identifying ten minutiae on all three fingerprints. It was then concluded that Alex Garcia’s figure print matched in ridge pattern and minutiae to the print found at the crime …show more content…
As well as the blood from the crime, we tested samples from all suspects and the victim. Each sample was divided into two. A drop of Anti serum A was placed into one half while a drop of Anti serum B was placed into the other half. The samples were then analyzed for any clotting in either half. After testing all samples of blood the crime scene blood was determined to be blood type B. However both Anna Garcia and Erica Piedmont also have blood type B. Thus concluding that the blood found at the crime scene could either belong to Erica or Anna. A DNA sample was then taken from the crime scene, Anna, and Erica to officially identify whose blood was found using gel electrophoresis. The restriction enzyme HaeIII, which cuts the DNA strand at the sequence GGCC, was placed into the samples of DNA and then ran through the gel. When the process was complete the crime scene DNA profile matched identically to Anna’s DNA profile with lines showing up at lengths 12, 23, 11, 33, and 24. After the conclusion of this experiment it was concluded that the blood found at the crime scene belonged to Anna
Anna Garcia is a thirty eight year old Hispanic women. She weighed 165 pounds and was 64 inches tall. She was married to Alex Garcia, but went through a nasty divorce. Anna has no children and one dog. A phone call came in at 9:45 AM on the hot morning of August 14th. Anna’s neighbor, Doug Greene let the police know he saw her walking her dog around 6:30AM yesterday morning, but heard her dog barking for the last two hours. Both the police and the EMT arrived at 9:56AM, and had to break the front door down. Upon entering the house, they found Anna lying face down in the entry hallway, a small pool of blood was by her head. The house was a comfortable 73 degrees fahrenheit. Around her there was evidence. There was vomit, blood spatters, blood on the table, and a pool of blood. As well as, a syringe, white pills, a cup with an unknown fingerprint on it, a muddy shoe print, and a
A review of the evidence suggests that Anna’s death was an accident. The blood found at the crime scene was that of Anna Garcia. While the fingerprint of Alex was located at the scene, the results show that he was at the house the night prior to the death. The pills found at the crime scene were aspirin. The time of death was 7:00am which was corroborated by her rectal temperature. The evidence points to Anna being the only one in the house, thus, ruling out homicide and other suspects being charged
Forensic science is a key aspect of Criminal Justice that helps rid the streets of lunatics and murderers. One of the most important fields of forensic science is blood spatter analysis. Under the Crime Scene Investigation, analysts gather the information that could eventually lead to a victim’s killer. Basic and complex information can be found when analyzing blood. We can learn what kind of weapon was used, the time of death of a victim and other important facts that can help a case. The pattern that the blood gives off give forensic scientists the tools that they need to help solve cases.
People who are different and ready for a change can be scary,society is one of the first people scared. Society pushes away people who are different from the norms. This happened in a time overlooked by many people. This was the time the young lords spent in New york. Kids and teenagers banded together to make as much as a difference as possible. Many tried to make a non-violent movement and were still shot down and told to silence their movement. Many middle aged Puerto Ricans raised in the United States disagreed with the action plan of the Young Lords,they believed the young lords were just causing trouble in each city they arrived in. They refuse to allow the idea of change into their mind as well as the minds of their children. They didn’t want the fight to make things worse for Puerto Rico’s freedom.
The analysis of the samples should be used only to confirm or negate match between the sample taken from the crime scene fgand the sample taken from the suspect. That is, it should sdfremain as an identifgication tool only. There should be no further analysis of the DNA to suggest psychological characteristics that would make the suspect more likely to have cdfommitted the crime. This rule should apply also to samples taken from convicted dfdoffenders for a data vor dagta bank.
Anna Quindlen describes in the essay “Abortion is too Complex to Feel one Way About” the different situation that we as a human race are put in everyday. She talks about the topic of abortion in a way that one feels they have had to make the decision of whether or not a person is pro-choice or pro-life. She uses references that are of different personal experiences in the essay that are vital to the audience. Quindlen is writing to state her point that one should never put their self in this situation because one should take the proper responsibility. In this paper you will read about the conflict with abortion and what Quindlen thinks about this issue.
The blood of the unknown person became apparent through comparing the blood type found at the crime scene with the contrasting blood types of the suspects. The blood identified at the crime scene could have possibly belonged to Anna Garcia or Erica Piedmont. This observation was based on the information that the blood type found at the crime scene was type A and these two individuals are the only ones that carry that specific type. In similarity, a microscopic photography was taken of the unknown hair follicle found at the crime scene. Then hair samples were taken from the potential suspects, and the victim. These findings were then compared. This was done by looking at each individuals hair follicles and comparing it with the unknown one. By looking at the similarities and differences in medulla diameter, the discovery of the unknown hair follicle became established that it belonged to Anna Garcia. Further examination resulted in the analyzation of a shoe print found at the crime scene. Shoe patterns and sizes were taken from each suspect, including the victims. They were then identified and compared to the one found at the crime scene. By looking at the distinct pattern, size, and the fact that both shoes were a Columbia brand sneaker it became obvious that the shoe print was extremely similar to Anna’s shoe design. Through this found evidence it became

If someone were to be torn from everything they know in order to live in a new country with a new culture and surroundings, they would face changes in themselves. Yolanda Garcia from the novel How The Garcia Girls Lost Their Accents, by Julia Alvarez, faces these changes in her identity and culture. After immigrating to America from the Dominican Republic, Yolanda is immediately confronted by the new culture that surrounds her. It leads her to feel insecure about who she is, and she feels the need to fit in with the Americans. Being a Dominican immigrant causes Yolanda to become insecure about herself and her culture, confused by the mix of two cultures she lives with, and to lose her sense of identity.
Caren Campano was a 42 year old woman working a decent job, and married to a man 15 years younger than her. Chris, her husband, was a drug addict that did not have steady income. The night she disappeared they had a large argument, and according to Chris, they both left the house in separate directions to cool off. She left on foot, and he left in the truck to a bar. The next morning he called her job asking if she was at work and they said she never showed up. He called and made a missing person’s report. The investigators went to their house and stated the house was in good condition, and did not look like she left. There was no signs of a fight. However, they found a large brown stain that was still wet next to the bed. When they tested it, it was positive for blood, and when they pulled the carpet back, there was an even larger blood stain on the cushioning under the
The three different main types of fingerprints are Loops, Arches, and Whorls (Jackson 1). Henry Faulds is known as the Father of Fingerprints and developing fingerprints (Jackson 1). His discovery of fingerprints has made a huge impact not only in his time but, in Modern Crime Scene Investigation (Jackson 1). Without fingerprinting, it would be very difficult to convict criminals of crimes and very hard to try to process information. Crime Scene Investigators make a huge impact in Forensic Science. We need CSI workers, without them people could only imagine what crime would be like not only in our community, but in our
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...
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
