There are only three basic patterns and they are loops, arches, and whorls. Loops cover about 60-65 %, whorls cover about 25-30 % and arches cover 5-10% of all fingerprints. These classifications can be divided even further like plain and tented arches, or radial and ulnar patterns. An example would be that an examiner found a set of fingerprints on a glass. Now they will be able to compare the prints to see if it has the same print pattern as the offender, which is a loop pattern. The loop pattern is a fingerprint class type, along with the arch and…
The result for the direct motion for Danny Driver (DD) will be granted, but the direct verdict for (FF) will not be granted. The court must determine whether the hitchhiker's estate had a prima facie case for negligence and could satisfy the burden of production to prove that both DD and FF breached their duty the day of the car accident that lead to the death of the hitchhiker.…
2. Forensic Scientists examine tiny fingerprint details. These may be loops,dots, forks, islands. Several comparison points must be perfectly matched for two fingerprints to be considered identical…
- A fingerprint may be small and unnoticeable to the eye, and even look like many other peoples, but they are in fact very different. Every fingerprint has a different pattern that is unique and unlike anyone else’s. I compared two fingerprints and found that they may look alike from afar, but up close one goes one way, while the other does something else and completely different.…
A fingerprint, in the context of forensics, is an imprint left from the friction ridges of any part of a human hand. Friction ridges are raised portions of the…
Ridgeway was a prime suspect in the 1980s but professed his innocence, passed a polygraph in 1985 and because of lack of evidence, he continued to murder defenseless women for at least 15 more years.…
How are fingerprints discovered at crime scenes? usually it is easy to be seen on items like plastic prints, however scientist are using a reflected ultraviolet imaging system to aim uv light where fingerprints might be, and if there a fingerprint will reflect the light back.…
The body count continued to add up and the case was news casted nationally. Ridgway was known as The Green River Killer cause he liked to dump many of the victims into the river. Later on he started dumping the victims in special places he called…
1. What are some of the challenges with fingerprint evidence? What is science doing to make fingerprint analysis better?…
Answer: The individuality of fingerprints is due to ridge characteristics, which are ridge endings, enclosures and other details. Forensic scientists look for point-by-point comparisons in order to determine whether two fingerprints are the same.…
A fingerprint reader, or scanner, captures curves and indentations of a fingerprint. Organizations use fingerprint readers to secure doors, computers, and software. For example, a fingerprint reader can be set up to authenticate users before they can access a computer (Rossi). External fingerprint readers usually plug into a USB port. To save on desk space, some laptops include built-in fingerprint readers1.…
Months later, on November 30th, married, 52-year-old father, Gary Ridgway, is arrested as he leaves his truck-painting job. Thankfully, it is the end of the longest running serial killer investigation in U.S. history; the break in the case was connecting the DNA taken when Gary Ridgway was arrested for the relatively minor offence of ‘loitering for the purposes of soliciting prostitution’. And this wasn’t the first time Ridgway’s connection to prostitutes had come to the attention of the police. In 1980, a prostitute he’d picked up accused him of driving her to the woods and trying to strangle her. Charges were dropped when Ridgway explained it away by saying she’d started to bite him while performing oral sex, and he only choked her to make her stop. Then again, in 1982, he was stopped with a prostitute in his truck and questioned by…
The most common strategy that forensic science experts uses is that fingerprints, bite mark and ballistics for the purpose of determining the real perpetrators of the crime. The reason is that when a person is involved in an offence and touches any of the items around the scene of the offence, the person's fingerprints are reflected on the item. Hence, the forensic team has a strategy of getting the fingerprints from all items found at the scene of crime regardless of the number of people that touched anything around the area. The most unfortunate thing is that the entire fingerprint-collecting process appears to be scientific in nature as it has a process that it is used to obtain the fingerprints. However, the process has over the time proved that the process is not entirely scientific a thing that has made the process to appear pseudoscientific. The reason is that a lot of biases have been noted to be emanating from the fingerprint process. A lot of inconsistencies, contradictory, and claims that the forensic team cannot prove has been…
Fingerprints are a standard part of a booking record, and are typically entered into a nationwide database…
The current methods of fingerprinting that involve subjective comparison and matching of fingerprinting has led to disapproval of the method. Extensive testing has shown that the results of fingerprint testing are not valid (Schmalleger, 2011). Fingerprint matches are now being done by experts, those fingerprints that have been previously been examined to make identification of suspects were presented to the same experts in a different context and the results were different. Similarly, DNA evidence for identification of criminals has been marred by several problems. Surreptitious DNA collecting, presentation of partial DNA profiles, and fake DNA evidence; cast doubts on the DNA evidence presented in courts (Schmalleger, 2011).…
