Today I arrived home from a longs day of work to find that my home has been burglarized. The officers were contacted by a neighbor that seen someone running from my home earlier today. Forensics was there collecting evidence and advised me to stay out of the home. The neighbor was not able to provide a description of the perpetrator. Officer Stone interviewed me and asked if I had any enemies or if I had seen anyone around that was not from the neighborhood. I have not noticed any suspicious activity in the neighborhood. I thought all was lost and they would never catch the person that has broken into my home. Officer Stone explained that forensics located some evidence that would help us. They bagged up a discarded piece of gum, hair …show more content…
I requested to speak to the head of forensics. CSI Mavis Jones said that she would be glad to assist me. I really wanted to know the process of analyzing and investigating the evidence. Jones stated the gum that was found could provide us with an abundance of information. She said gum could provide dental information of the perp. We most likely would be able to determine the sex of the perp. This technique would be based on the sizes of the teeth. Enamel protein is different in women and …show more content…
The hair that was found at the scene was gold. She said they will be able to find out even more from this evidence. She said the examination of human hairs in the forensic laboratory is typically conducted using light microscopy. This examination routinely involves a two-step process the identification of questioned hairs and the comparison of questioned and known hairs. (Deedrick, July 2000, FBI Unit Chief) They can determine where the hair has come from (what body part) and if it is human or not. They could also determine the race, age and sex from a single strand of hair with root
A common tool that forensic units use is the ultra violet or UV light. Ultra violet light can detect different areas that contain blood that might not be able to be seen in other conditions. Another common tool is the blood reagent test that forensics use on scene. These tests determine if the blood is human or animal. Renee Blake - "The 'Renee Blake'" There are different types of bloodstain patterns that give a sense of what happened at the scene.
... tested hairs and other parts for DNA and concluded that they fit into our family tree. “ Those hair samples that could not be identified as known animal or human were subsequently screened using DNA testing, beginning with sequencing of mitochondrial DNA followed by sequencing nuclear DNA to determine where these individuals fit in the tree of life” (Ketchum 2013).
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
A forensic evaluation is a comprehensive and elaborate process that incorporates collection, analysis, and integration of information form multiple sources. Child welfare related evaluations are one of the most complex types of forensic evaluations requiring expert opinion and recommendations on matters pertaining to child custody and visitation, parental fitness and termination of parental rights, and evaluation of adoptive and foster parents. The primary purpose of these evaluations is to inform the court and facilitate decision-making process in child welfare cases. During a child custody evaluation the main doctrine to uphold is the “best interest of the child.” The safety of the child is of paramount consideration. This along with well-being
If i was an investigator i would be looking for fingerprints on the subject. You know things that will help me find the murderer who killed that person.
Risk assessment is the process of understanding a hazard such that its potential negative impact can be limited. In forensic services, violence risk assessment and management are critical elements of the delivery of services by professionals from various disciplines including psychology, psychiatry, nursing, social work, and occupational therapy (Hart, 2001; Doyle & Dolan, 2002). These professionals hold an ethical and legal responsibility to prevent or limit future violence by their clients. This serves to ensure not only the safety of the public from violent acts, but also that of healthcare professionals who may be involved in the care of potentially violent individuals, and the clients from self-harmful consequences of violence (Hart & Logan, 2011).
These hairs may be of evidentiary value to show contact between two people. With an adequate hair standard, a trace chemist will be able to microscopically compare an unknown hair to a standard collection and determine if the unknown hair could have come from the individual under investigation. Hair comparisons can not identify hair as coming from one individual to the exclusion of anyone else. DNA testing can strengthen any possible association with the hairs." - Locard.... ... middle of paper ... ...
The Forensic interview technique is a result of the increasing awareness of child abuse and neglect cases in the United States in the last quarter of the 20th century (Newlin et al, 2015). Forensic interviewing has come a long way from when it was first being developed and has continuously evolved to have the best outcome for children. The purpose of Forensic interviewing is to be more child friendly, to consider the age and development of the child, and to be cognizant of a child’s trauma which is specified in the “Purpose of the Child Forensic Interview” and “Considerations Regarding the Child” sections of the Newlin article. Forensic interviewing has become more specialized and developed since it first began to be utilized. It has developed
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.
Strands of human hair situated at the crime scene gives exceptionally solid sign that an individual was at that area, yet it can likewise be useless if the fibres were found outside and, subsequently subject to the elements such as wind, and if the full length of the strand is not present (Dasgupta, 2007). Hair without anyone else 's input is essential, but rather the most imperative DNA evidence connected with hair fibres originates from the cellular material at the root of the hair strand. In a way, the microscopic particles of follicle give the most solid proof. The protein called keratin is the key substance that goes with the follicle, and that gives the best distinguishing proof. On the off chance that the hair is taken off by the root, for example that could happen when an individual is guarding him or herself against an attacker, then the hair fibres are essential (Innes, 2000). Hair that does exclude follicular material is a great deal less dependable. Hair fibres that do exclude keratin are helpful in distinguishing a category of individual into which a suspect may fit, however they are not complete evidence that the hair originated from the suspect (Innes, 2000). Therefore, personally, hair fibres are less important than fingerprints and DNA evidence acquired from saliva or blood. Fingerprints are not DNA evidence, but still they are extremely dependable types of evidence. DNA obtained from bodily fluids, in any case, is the most profitable type of evidence
Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice
In regards to hair analysis, it must be presented along other evidence, as it is class evidence. Therefore, a person can not be indicted solely on hair analysis due to it being circumstantial evidence. When analyzing it, the areas
Jury, I am Natalie Wright and I am here to inform and describe to you about the specifics, analyzation, and documentation of hair that is collected. Hair that is collected is sent into the lab for precise analyzations on what foreign toxins could be possibly discovered in the specific specimen and where the hair could have originated. Hair is such a common thing that it would seem almost unnecessary and trivalent to spend time analyzing over. Although, hair aids us in finding extremely important information of the people we could possibly be dealing with since it contains the DNA of the individual. It’s a precise method of identification, which is why I am here to explain and prove my point correct to all of you.
