Dna Fingerprint Case Study

350 Words2 Pages

Describe how a technician would collect a fingerprint from a weapon that could possibly have touch DNA on it as well as fingerprints. How would you collect the possible DNA? Which would you collect first? As we go about our day we inadvertently leave behind our unique friction ridge impressions in items we come in contact with. Within those impressions, sebaceous secretions, eccrine sweat and apocrine sweat reside on our pores containing our individualized DNA. Therefore, small traces of DNA in one’s skin cells are transferred to the items we come in contact with. With the recent advances in DNA technology, only seven or eight cells from the outermost layer of our skin is required to process the DNA. When collecting samples from fingerprints

    In 2003, the Innocence Project filed a motion for DNA testing on skin cells collected at autopsy from underneath the victim’s fingernails. Because she has defense wounds on her hands the biological evidence form the attacker could be under her fingernails. She had defense wounds on her hands, meaning that biological evidence from the attacker could be under her fingernails. The DNA test results showed that male DNA under Tina’s fingernails did not come from Chad or Jeremy Heins. Additional testing in 2005 showed that the profile from the hairs was consistent with the DNA from the fingernails, all belonging to a single, unknown male.

    The leader of this group, named Deirdre, said that scanning extra objects for DNA is important, ”When I talked to DNA experts that they were saying, ‘Yeah, I mean, if you swab that and get some skin cells or saliva and it’s just random, you get no hit on anybody, well then it neither here nor there.’ But they were saying, ‘but if put it in and you get a hit on a serial killer… well now you got enough to charge and convict somebody.’ So what you call relevant and irrelevant you can only do once you have a test result” (111). Deirdre likes to test anything that could possibly lead them to another suspect in the crime. Not everyone in the detective business is, however, not like her.

    The DNA is loaded into wells in the gel that are made when creating the gel. Since DNA is negatively charged it will repel the negative charge in the gel box, and move towards the positive end. This will separate the bands to make a pattern. Then the pattern created will be used to analyze other DNA samples to find the suspect. If every single band matches between 2 DNA well tests, that means that they came from the same person.

    Fingerprint analysis is a method of identifying individuals based on the unique patterns of ridges and valleys on their fingertips. In Dahmer's case, investigators were able to use fingerprints to identify the remains of his victims and link them to specific crime scenes. Fingerprint analysis has been used in forensic investigations for over a century and is considered to be a highly reliable method of identification. It is based on the fact that no two individuals have the same fingerprint patterns and that these patterns remain consistent throughout a person's life. In Dahmer's case, fingerprint analysis was used to identify the remains of several of his victims, including Anthony Sears and Ernest Miller.

  • The Pros And Cons Of Fingerprinting

    1172 Words  | 5 Pages

    Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

    DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
