The crime scene was then examined and a list of possible pieces of evidence were recorded down. Including a sketch of the crime scene, Anna Garcia’s house, with the locations of all of the pieces of evidence. All of these items listed help develop a theory about Anna’s death. This theory then helped establish a list of possible suspects. The person of interest list included a number of four individuals and each one had a relation with Anna. The list included (1) Alex Garcia- Anna’s ex-husband. They had an unpleasant divorce the year before and in a result Alex quickly remarried a much younger woman, while Anna remained single. Alex and his newlywed wife are expecting to have a baby soon. Although, Alex may be suffering from a few financial …show more content…
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 …show more content…
The autopsy report included the following information: Office of the Medical Examiner, Urban Government of woodland: Case #77, Deceased- Anna Garcia, Age- 38, Weight- 165 lbs, Height- 5’4 (64 inches), Race- Hispanic, and Sex- Female. The autopsy took place on August 15, 2011 at 11:00 A.M. and was performed by Dr. King. The category about the toxicology report in the laboratory results stated that there was no evidence of alcohol- BAC (% by volume) 0.015. Although there were trace amounts of acetylsalicylic acid (aspirin) present, there was no evidence of an overdose of prescription or nonprescription drugs. The autopsy report continued with a external examination. The general appearance of the body was described as a well developed, healthy 38 year old Hispanic female who weighed 165 lbs and was a height of 5’6 (64 inches). In addition, there was no evidence of postmortem tampering and rigor mortis is generalized. When considering the clothing and valuables it was identified that there was a ring located on her right ring finger, clothes were not torn but were stained with blood, and there was a small portion of vomit on her right shoulder area of her blouse. Likewise, the head and neck is ordinarily shaped with medium length, black hair. Even though the neck showes no visible signs of injury, there is an injury to the right temple. Including an open wound where pre-mortem
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
Finding out Anna’s cause of death means investigating suspects. Some of the suspects that were interrogated were Lucy Leffingwell who was Anna’s best friend and business partner, Erica Piedmont the new wife of Alex Garcia who was found fighting with Anna at a local diner and was later spotted in Anna’s driveway. The last suspect is Alex Garcia, he is a major part of the investigation because the fingerprints that were
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
Forensic Science Introduction: Someone in a restaurant has suddenly fallen ill and a mystery powder has been discovered with the victim. As the chief investigator, your duty is to identify the mystery substance through a lab. In this lab, it will consist of five known compounds and one unknown compound. Your job is to distinguish which one out of the five substances is the mystery powder. To figure out the mystery matter you will have to compare their physical and chemical properties and match them with the appropriate compound.
...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.
Kayleigh Slusher, a three years old baby girl in Napa Calif. the little baby girl lives with her mother and the mother’s boyfriend, while the real father is in jail. During that time, police often gone the house to visit and check up on the little child well-being and making sure everything is ok, the mother was check on also. On Jan. 30, Kayleigh’s body was found in a suitcase inside a freezer that was left for three days, the body of the child was also found with bruises and sexual assault, the mother (Krueger) and her boyfriend Ryan Scott Warner was arrested at El Cerrito Bart station near a restaurant.
Anna Garcia was found lying facedown in the entry to her home at around 9:56 am. The EMT and police were notified by Anna’s neighbor, who called 911 because she wasn’t answering her phone or the door. It was determined that her approximate time of death was 7:00 am. CSI team canvassed the scene and found a syringe, orange liquid (assumed to be orange juice) by her left hand, as well as hair and blood on a fallen table to her left. Several people were persons of interest in this case. They include Anna’s former husband (Alex Garcia), the neighbour that called 911 and was recently involved with her (Doug Greene), her ex-husband’s new wife (Erica Piedmont), and her friend/business partner (Lucy Leffingwell).
Crime is a common public issue for people living in the inner city, but is not limited to only urban or highly populated cities as it can undoubtedly happen in small community and rural areas as well. In The Real CSI, the documentary exemplified many way in which experts used forensic science as evidence in trial cases to argue and to prove whether a person is innocent or guilty. In this paper, I explained the difference in fingerprinting technology depicted between television shows and in reality, how DNA technology change the way forensics evidence is used in the court proceedings, and how forensic evidence can be misused in the United States adversarial legal system.
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
Trace evidence is a study that identifies and compares specific types of evidence that can be transferred as a trace material during the commission of a brutal crime. Trace materials include animal hair, human hair, textured fibers and fabric, rope, feathers, soil, grass, and building materials. For animal hair and human hair, examinations are done to determine if the hair is either human or animal. If the hair is animal, then the species and breed can be determined. If the hair is human, racial characteristics, body area, length, root type, treatment, and dam...
In here I will clarify each potential evidences of the crime and explain of the application of the identified forensic procedure to the facts of the case. One of the perpetrators cuts his hand when trying to drag of the witness in the crime scene. Thus, in this case blood stains would be the one of the potential evidence. The precipitin test might be applied to bloodstains in a numerous ways. It conduct...
Ed Gein was the center of attention in the most infamous way imaginable. The scenes he left after his crimes were not that far from the typical murder. The first crime scene attributed to him was a local tavern owned by Mary Hogan, a middle aged woman who resembled Ed’s mother but had a foul mouth in comparison; blood stains and an empty .22 bullet casing on the floor were the only evidence there. Gein later confessed to drinking with her that day, then closing the blinds and shooting her in the head with a .22 caliber gun (Ed Gein, 2009). The other crime scene Gein confessed to was a harvest products shop where he killed owner, and mother to deputy Frank Worden, Bernice Worden, 58. There sheriffs found
Collecting evidence from a crime scene is a crucial aspect of solving crimes. Before evidence can be seized, there must first be a court order approving the search of the crime scene and the seizure of the evidence found at the scene. Standard protocol for officers is for them to always use latex gloves, avoid plastic bags, double wrap small objects, package each object separately, and to collect as much evidence as possible. It is better to have too much evidence than to not have enough. There are countless amounts of evidence that can be found at a crime scene.
Crime Scene Investigation For my assignment, I will be looking into the case of James Bulger, aged 2 years old, who was kidnapped and murdered by John Venables and Robert Thompson on February 12th 1993. Through evidence found at the crime scene and testimonial statements, the police saw that the two boys, ages 11, abducted James from Bootle Strand Shopping Center, Liverpool. They took him on a long, aimless walk where they brutally attacked him and left him for dead. In my assignment I will show how work done by the police, forensic scientists and Investigators helped to convict Jon and Robert.
There are several steps that need to be taken in order to process a crime scene. Some of the steps include: securing the scene, a detailed search, documenting the crime scene, collecting and preserving evidence, and finally releasing the scene. All of the following steps are crucial to avoid any possible contamination or otherwise compromise the scene before it can be released. Few, if any additional opportunities exist when processing a crime scene, so the first time is most pertinent.
