Regression Analysis: Loyola Rambler's Fingerprints

Identifying who the guilty are is much easier said than done. Identification of the guilty has been an issue for a long time. Often such identifications consisted of using discriminatory categories in order to identify suspects. The police have been discriminating individuals based on their gender, skin color, race, eye color, height and weight (Ingram, 2009). However, these descriptive characteristics are not the only ones the police were using, in fact, blood typing, fingerprinting, and DNA matching, have been added to the list (Ingram, 2009). These types of identification methods cannot be disputed as easily. Of course, DNA can be tainted and people can be framed, but for the most part, it was better

According to the Federal Bureau of Investigations (1991), most of the victims found in Dahmer’s apartment were identified through fingerprint, DNA, and dental analysis (FBI, 1991). Medical Examiner, Jeffrey Jentzen visited the scene while officers and the forensic teams photographed, documented, and collected the evidence. Throughout the ordeal, Jenzen continued to work with the federal Bureau of Instigations laboratory to identify and examine the remains of the victims (IFC Films, 2014). The laboratory specialists on the case conducted DNA profiles, tool marking analyses, fingerprinting, and photographic and computer examinations on the evidence submitted (Federal Bureau of Investigations, 2016). Forensic Odonatologist, Dr. L. Thomas Johnson aided in establishing positive identifications of nine of the individual’s by examining the victim’s teeth in comparison to their previous dental records (Bennett, 1993, p.

Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA

At the scene of the crime fingerprints were also found. As a team, we concluded that the fingerprints belonged to Alex Garcia. When comparing the fingerprints at the crime scene and the suspect’s prints, we looked at the ridge pattern and the minutiae. Alex Garcia’s ridge pattern matches the ones at the crime scene, a loop. He says he was at work at the time, but he has no alibi witness. In 2008 Alex Garcia had a restraining order placed on him by his ex-girlfriend do to violence. Alex never did really go to work. If Alex’s fingerprints were at

Tashanna N Garcia is currently enrolled in the Masters of Criminal Justice, with a concentration in Forensic Science, program at Saint Leo University. Tashanna comes from a military background where she served as an officer in the United States Marine Corps. Her military training was essential to her transition into law enforcement, where she spent the last ten years working for two police departments as a patrol officer and then for the Alabama Department of Public Safety as a Traffic Homicide Investigator for the State Troopers. Tashanna hopes to return to the law enforcement field in an administrative capacity and has a passion for forensic disciplines. Correspondence concerning this paper should be addressed to Tashanna N Garcia,

How: In late 2008, the Omaha Police Department received an inquiry on the case, prompting technician Laura Casey to search the prints against IAFIS (which didn’t exist in 1978). In less than five hours, IAFIS returned possible candidates for comparison purposes. Casey spent days carefully examining the prints and came up with a positive identification, Jerry Watson, who was serving time in an Illinois prison on burglary charges.

Due to the brief period that Hodge had been allowed to see her attacker, the prosecution felt that stronger evidence was needed to prove a connection. The brief 6-second glimpse that the victim Nancy Hodge obtained during her ordeal wasn’t considered viable enough for trial purposes (Lewis). This relatively new forensic investigation technic involving the use of DNA fingerprinting was in its infancy and was pioneered by a British scientist might hold the answer to convicting the rapist.

On the other hand blood spatter on a rough surface creates a blood stain with japed edges. Also Blood strains spread more in softer surfaces. Blood usually makes a spherical shape after separating from the blood source, this shape caused by the surface tension of the blood. The blood drop to pull itself in; both horizontally and vertically due to its surface tension, and will maintain its shape until it collides with something. Blood usually will not break unless acted on by a force, and the force has to be great enough to overcome surface tension. When a drop of blood hits the floor at a 90 degree angle the spatter will be round. A low-velocity spatter will be dependent on height, when distance fallen increases the blood spatter will

Summary: This fingerprint was collected at the home where Jessica Lunsford’s body was located by the Citrus County Police at which point I photographed, lifted and collected the print, and secured it in my vehicle. After I further examined it, I gave it to the officers for them to be able to use it in the upcoming case as evidence.

For over a century fingerprints have been one of the most used tools of forensic science. Fingerprints have been used to identify criminals of small crimes

The first case of Brandon Mayfield describes a partial fingerprint found by authorities on the bag of detonators in the 2004 subway in Madrid, Spain detonations killing approximately 2,000 people. The Federal Bureau of Investigation (FBI) for generations routinely testifies as fingerprints being “infallible” with no chance of being wrong. By the same token, backed by independent expert Kenneth Moses he confirms the FBI analysis was correct. Never the less, the Spanish Police identified another individual

3. Compare the financial results from Question 1 and 2 and highlight your observation regarding contribution. Based on your calculations, what is the relationship between volume and cost?

Since the maximum value of the predictor variable (calls) is used to formulate the given regression model is 201.00, which is less than 300, we cannot use the given regression model to accurately estimate the weekly sales for weekly call of 300. So we can’t say anything about the weekly sales when weekly calls are 300.

Fingerprint Evidence. Dr. Ruxton had gone to great lengths to cut off fingers, feet, and the heads of the women. He also removed all prominent features to include, eyelids, skin around scars and birthmarks (Owen, 2009). However, investigators were still able to match the fingerprints of remains to dinnerware at the Ruxton home. This provided conclusive evidence that one of the bodies belonged to Mary Jane Rogerson (Owen,

Every time somebody touches something, they leave behind a unique signature that forever links them to that object. This link is their fingerprints, which are unique to every person, for no two people have the same set, not even family members or identical twins. Palms and toes also leave prints behind, but these are far less commonly found during crime scene investigations. Therefore, fingerprints provide an identification process that is applicable to background checks, biometric security, mass disaster identification, and most importantly, crime scene investigations. Fingerprints are so differentiated because they are made up of distinct patterns of ridges and furrows on the fingers. The ridges are the “raised” portions of the prints, and the furrows are the “recessed” portions. This perceived uniqueness has led some people to falsely accept fingerprint analysis as absolute scientific fact. Although overall fingerprints are reliable, there are definitely situations where their accuracy can come into question.
