Previous Cases: For drug processing, we will examine a case that focuses on the supply of controlled drugs. With the help of Forensic Science Service (FSS), it has been engaged in the development of the framework that provides a consistent, robust, and a balanced approach to forensic science casework (G. Booth, 2002). FSS is seen in this case. The case will compare the wraps of two suspected people. The findings are based on the maximum value, clarity, and balance of the product. Although for fingerprinting cases we will inspect the Mayfield case and People v. Collins. Mayfield was a case about the Madrid bombers (Dror & Mnookin, 2010). Somehow there was a similarity between one portion of one of his fingers and the portion of the latent print …show more content…

Some of the steps for them, we will focus on anything drug related. That being if drugs were related to the cause of death. By checking the personal belongings, even in the crease of skin for evidence of drugs. Afterward, check the body for possible needle marks either in plain view or hidden. If it was a suspected overdose they reveal of pills or chalky white materials could be found in the stomach. Collect and retain samples of bodily fluid for potential toxicological analysis is always appropriate in every autopsy that is undertaken to determine the cause of a person 's death (Gregory G Davis, 2014). Urine is ideally suited for a rapid screening, but blood or even brain matter is also suitable samples for …show more content…

Ways to collect the prints is through photographs or type. Submit the intentionally recorded prints of everyone who may have handled the evidence, including the suspects and victims to help narrow down or eliminate to find the right person (FBI Laboratory Publications, 2013). Tying in the drug processing and fingerprinting, you can search for a latent print on a drug packaging materials. The drug item should be separated from the original packaging when it is reasonable to do

We came to this conclusion not after our recordings of our observation, we also added drops of various indicators to each substance sample. By doing this, we were able to see the various reactions with each indicator to see which substance matched the reactions of the unknown substance found at the crime scene. The substance at the crime scene reacted with bubbling when each indicator, as did the Acetylsalicylic Acid, confirming the identity of the substance At the crime scene we also found a series of blood spatters as well as a pool of blood near Anna’s head. Not only did the blood provide us with DNA evidence, we were able to conduct a series of tests allowing us to figure out whether Anna fell and started bleeding or was already on the

The reasoning was because the cuticle and the medullas are similar in comparison. The unknown substance found at the crime scene turned out to be Acetylsalicylic acid because it had the same appearance and reaction as an acid. The time of death of Anna Garcia was approximately at 7:00 am. The blood spatter lab concluded that as the height of the blood droplet increases, then the diameter of the blood spatter increases. The DNA found at the crime scene was Anna’s DNA.

The primary types of forensic evidence found at Ramírez’s crime scenes were fingerprints and bodily fluids. Unfortunately, DNA profiling for use in the criminal justice field was still very new in the mid-1980s (Waring) so bodily fluids found at the crime scenes were not as helpful as they would be today. However, Ramírez’s fingerprints proved to be very effective when presented to the jury as evidence and have largely been credited as key to his conviction

Among them were things like distinguishing slash wounds in five murders across the victim's necks, similar handcuff marks on various victims' wrists and blunt force head trauma to half of the victims (Chen, 1989.) Shoe prints were also left at the scene of two murders, the shoe prints had to be either a visible print, plastic print or latent print. Examiners use several methods in the collection of shoe prints depending on the type of impression that is left at the scene of the crime. For collections in soil, which was where the print was found in the Ramirez case, casting is the most commonly used collection method for analyzation. The evaluation and comparison of impression evidence is usually performed by a trained footwear and tire mark examiner (NFSTC, 2013).

It is necessary to lay down statutory guidelines regarding the procedure to be followed by the law enforcement officials during investigation of the criminal offences so that they do not resort to illegal arrests, unlawful searches and seizures, coercive interrogation and illicit means to collect evidence. Procedural norms are essential for regulating the proceedings in the court of law. The procedural provisions are indispensable components of any penal statue. In the Narcotics Drugs and Psychotropic Substances Act, all the procedures required to be followed by the enforcement officials during the investigation have been exhaustively dealt with.

In present-day scenario hair has become a vital biological sample, substitute to the usual samples blood and urine which are found at the crime scene, for drug testing in the different fields like forensic toxicology, clinical toxicology and clinical chemistry. Furthermore, hair-testing is now extensively used in workplace testing and at legal cases, historical research etc. Hair structure and the mechanisms of drug incorporation into it are discussed. The usual training and withdrawal methods as well as the analytical techniques of hair samples are offered. The conclusions of hair analysis have been reviewed for the following categories: drugs of abuse (opiates, cocaine and related, amphetamines, cannabinoids), benzodiazepines, official drugs, pesticides and biological pollutants, doping agents and other drugs or substances.

Also, some chemicals used to process fingerprints deteriorate with time. The deteriorated prints would not be reliable in the event they are needed years down the line for possible retrials or appeals. At the crime scene, I would collect prints from any items that I believe the print would be damaged while being transported, fragile items, or items that cannot be taken to the laboratory. For nonporous items, I would use latent print powders or cyanoacrylate fuming. Cyanoacrylate fuming can be used on nonporous surfaces before and after packaging to develop the fingerprints contained on them.

Next, they make sketches of the crime scenes. Then, they must record observations and findings such as location and position of the evidence. Next, they collect evidence which includes weapons, fingerprints, and bodily fluids. Last but not least they catalog and preserve evidence for transfer to crime labs. Once to the lab they, perform chemical, biological, and microscopic analyses on evidence taken from crime scenes.

Crime Myths Most crimes are solved by fingerprints and DNA. This is a prime example of a crime myth. The truth is less than 1 percent of all serious crimes are solved by DNA, and fingerprints do only slightly better. As mentioned in USA Today titled "Crime and the media: Myths and reality", it discusses some of the important insight to crime in the media causing myths. Another source that covers this topic is in an Irish Times article by O’ Toole, Fintan entitled “Myths that conceal the truth about roots of crime: [CITY EDITION]” it goes over the many aspects that relate to myths that are contributing to the truth about roots of crime.

We have gone from throwing a little dusk around, taking some photographs, or maybe picking up something discarded to having to know the temperature in which an item can be stored in a refrigerator (Fantino, J. (2016, 04/02/2016). The elements of forensics, especially the relevance and application has become so sophisticated that most law enforcement personnel would not know heads or tails of one type of particular science to another. The education of the responding officer as to the procedures of gathering evidence should be of the utmost priority, as it sets the foundation for the criminal
