Temperature Synthesis Essay

605 Words3 Pages

For 10 tests, a total of 180 samples are used on 3 different surfaces and under 6 different temperatures for each test. Four tests have been performed quarterly and a total of 720 samples are prepared. In order to prevent mixing of samples and contamination, information about volunteers were written on labels.
Temperature Values:
Samples taken out from test environment were exposed to temperatures of 50oC, 90oC, 110oC, 150oC, 200oC, 300oC for 3 minutes at each degree.
Fingerprint Development Process: Out of the samples which were exposed to different temperatures; "Super Glue" and "SPR" method is applied to metal and glass samples and "Ninhydrin" method is applied to paper samples to investigate whether fingerprints would develop or …show more content…

"Super Glue" method is used for metal and glass samples and "Ninhydrin" method is used for paper samples which have been exposed to different temperatures to investigate whether fingerprints would develop or not. High quality scaled photo shooting and image intensifying (Photoshop) process is applied to each sample in order to assess if they are suitable for identification or not.
Results of fingerprint samples on different surfaces belonging to each volunteer are classified basing on the classification system used in Turkey and taking at least 13 fingerprint characteristics with regard to they are classifiable or not.
When we assess the study in terms of fingerprint development:
· It is determined that fingerprints on glass surfaces are more suitable for comparison than the ones on metal and paper surfaces..

Chart 1: Assessment of fingerprints with regard to surface types and time

· When the total number of comparable fingerprints is considered; it is found that the number of comparable fingerprints decreases from month 0 to month

    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.

    There is powerful verification that fingerprints aren’t foolproof. In “ Forensic Science: Evidence, Clues, and Investigation” by Andrea Campbell, she gives a strong explanation of how forensic science plays a vital role in solving criminal cases. Campbell has shown that forensic evidence is unquestionably the most dominant type of evidence to present at a trial. In the same way, “...unless the criminals take something away from the crime scene, hard evidence does not leave.

While this reaction is not a common occurrence for most of us in our daily life and work, it is in a forensic science lab. This chemical reaction is just one of the many techniques used to unveil fingerprints in a crime scene. Unfortunately, fingerprints are not always left or able to be found. In that case, new chemical procedures must take place.

Student two’s DNA matched exactly with the suspects DNA; the other two student’s DNA did not resemble the suspects DNA at all. (Choi, et al, 2008) DNA fingerprinting is used a lot in determining who committed a crime.

    Fingerprint analysis can be collected in different ways, some forensic scientists use tape lift, where they place the tape on the can and they can get the fingerprint, but others use a different method, depending on the situation. In the article called “Fingerprint on beer can helps solve nearly three-decade old case,” by Zack Peterson: “A fingerprint on a beer can put a 49-year-old Alabama man in jail Wednesday for his role in a homicide nearly three decades ago (2017).” Once they interrogated Reeves, at which point he had already had a lawyer with him, he then confessed to the crime, he said that it was out of passion, in 2016, they finally announced that he was a match, and the only thing Reeves had left was confessing and he did. He served already a year in Silverdale Correctional Facility, and the rest is going to be served at home, through probation. Grand jury was used in this case, and that was how the case was resolved, he was first sentenced to 7 years but since he had minimal prior criminal record he was given around a year and then the rest was served with probation.

  • Richard Ramirez Analysis

    1776 Words  | 8 Pages

    The Richard Ramirez "Night Stalker" case was one of the first major cases to use automated fingerprinting technology (Frese, 2011). Today, the fingerprinting database gives various probable identifications, then a trained fingerprint expert must compare the prints to find a likely identification. Considering that Ramirez's prints were found on the mirror of a stolen vehicle we can conclude that his fingerprints were two-dimensional, therefore the prints are termed as latent or residue prints. The authorities at the crime scene power-dusted his prints considering that is the best physical method for collecting fingerprints. Once analyzed using the ACE-V (analysis, comparison, evaluation and verification) method, the fingerprint expert was able to identify them as belonging to Ramirez.

  • 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).
