Upon further analysis of the woman’s bedroom, the forensic officers used a chemical called amido black. Amido black is a protein dye that is sensitive to the protein in blood and when it makes contact stains a latent blue-black colour. It is used for revealing fingerprints, trace evidence, and fibers that may be in the crime scene. This technique was not useful for the officers because they could not find any prints or evidence. The forensic officers also performed an ultraviolet light test which was used to reveal trace evidence such as vaginal fluid, urine, semen, or saliva. The ultraviolet test is usually done before using chemicals such as luminol to see if there are any fibers to be found and used first. However the officers were not able to find anything, but this method was useful to them because they could not find any evidence to prove that

There are three types of environments in which cells are located which include isotonic, hypotonic and hypertonic. In an isotonic environment, the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell, the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of water on the outside of the cell and a high amount of solute inside the cell, water will be drawn inside of the cell creating a hypotonic solution. The increase in water inside the cell causes the cell to become engorged and erupt. In a

Hospital acquired infections (HAIs) affect over 1.7 million patients each year, causing almost 100,000 deaths annually in the United States alone (Johnson, 2010). According to the World Health Organization, HAIs are the most frequent adverse event in the healthcare industry. Fortunately, most of these infections can be prevented with one single intervention, proper hand hygiene (“The Evidence,” n.d.). Four out of five pathogens that cause illness are spread by direct contact. Proper hand hygiene eliminates these pathogens and helps to prevent cross-contamination and HAIs (Linton, 2015; “Hand Hygiene,” n.d.). Reduction of cross-contamination and HAIs improves patient outcomes, increases employee wellness, and lowers health care costs. Adherence to proper hand hygiene is the single most important safety measure in the health care setting. However, for many years compliance to proper hand hygiene in the healthcare industry has been dismally low. New and inventive measures must be implemented to increase compliance to proper hand hygiene and lower the rate of hospital-acquired infections.

The world of Forensic Scientist is an amazing and fascinating place. There are so many aspects that go into forensic science but in this paper we are only covering bloodstain spatter patterns. Bloodstain spatter patterns are not solely used to solve crimes but I do feel it is one of the most important. Bloodstains never lie.

This test is used to detect the hemolytic activity in the bacteria. A darkish green color on the media around the bacteria would represent incomplete hemolysis. A transparent media around the bacteria colony represents complete lysis of the red blood cells. If no change is observed around the bacteria colony then the bacteria is non-hemolytic. For my

Beginning in the mid-1980s, the development of DNA analysis technology has revolutionised the field of forensic science within the criminal justice system. As the refinement of procedures and technology continues, even minute samples of biological material (including blood, saliva, semen and skin cells) are able to be analysed and used to link or acquit perpetrators of crimes. (Whitney, R n.d.)

The Louisiana State Police Crime Laboratory was developed to provide the highest quality of professional forensic services to the State of Louisiana. The commitment of the agency includes applying sound scientific principles in all analyses, being responsive to our customers, conducting our operations in a fair and objective manner, and being a leader in advancing forensic science. The mission of the laboratory is to assist all of the local, state, and federal law enforcement agencies in Louisiana in the investigation of criminal activity (Office of Public Safety Services, 2015). The agency is also committed to providing accurate and timely scientific analysis of items of physical evidence and reporting the results of those analyses to appropriate entities in the criminal justice community.

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,

Bloodstain pattern analysis (BPA), known in the criminal justice field as blood splatter analysis, has been studied since the 1890s. Blood splatter, or bloodstain pattern constructional readings, is a technique that seeks to piece together the incident that caused an individual’s bleeding. Understanding blood splatter on a wall or various surfaces can be instrumental in formulating if a crime was committed and if the blood discovered at the crime scene can be used as evidence. The first documentation of blood splatter research occurred at the Institute for Forensic Medicine in Poland, by Dr. Eduard Piotrowski . During Dr. Piotrowski’s research and documentation period, where he used live bunnies to research blood splatter from head

Forensic science is a key aspect of Criminal Justice that helps rid the streets of lunatics and murderers. One of the most important fields of forensic science is blood spatter analysis. Under the Crime Scene Investigation, analysts gather the information that could eventually lead to a victim’s killer. Basic and complex information can be found when analyzing blood. We can learn what kind of weapon was used, the time of death of a victim and other important facts that can help a case. The pattern that the blood gives off give forensic scientists the tools that they need to help solve cases.

The book gives a general overview of the field of forensic science. The sections of the book include “The Scene of the Crime; Working the Scene--The Evidence; Working the Scene of the Body Human;

Hands were wet by a running tap and antiseptic detergents or liquid soap (5ml was poured onto the hands, the technique consisted of five backwards and forwards strokes in the motion of; palm to palm, each palm over the other hand’s back, interlocking palm to palm, each palm over the other hand’s back interlocked and then the rotational scrubbing of the fingers into each palm finalised by the rubbing of the wrists during a 30-second time span. Then the hands were rinsed with water for 15-seconds and dried with two paper towels for 15-seconds. (Ayliffe et all, 1978) Whilst this technique has strict timescales the WHO elects the timescale of roughly the time taken to sing “Happy Birthday” twice. This raises concerns over the approximates as this will differ from person to person. The procedure itself remains nearly exact except from the addition of turning the tap off with a towel to avoid recontamination and the exact timings are lost. This technique only stated to use running water, however no temperature was specified. Hand Washing for Life (200-) advises that water should not be above 110F as this temperature would cause hands become damaged by loosing delicate tissues on the skin. This can cause bacteria to become trapped and more difficult to remove, as well as cause pain to the worker. It is a legal requirement for health professions to take the necessary measures to

People who watched crime-based television shows understand that DNA evidence is not always noticeable at first glance. In fact, in some cases, it can be impossible to detect visually. Take semen, for example. In large amounts, seminal fluid is easy to detect. It leaves a noticeable crusty stain on most fabric. However, if that fabric is washed then the stain is gone. Presumably, the evidence is washed away. This is not the case necessarily. There are several methods forensic scientists use to find traces of semen to identify a male’s identity. The Acid Phosphatase Color Test is widely regarded as the most effective way to both locate and characterize a seminal stain.

Today, more than ever, the quality of evidence in criminal cases is scrutinized because of contamination. Contamination is the introduction of something that physically corrupts a substance at a crime scene that was not previously there; it comes in many forms and most often times comes from the humans who investigate a crime scene. It is imperative that prevention of cross-contamination is implemented when gathering evidence. Several of the more sensitive forensic techniques such as trace analysis, bloodspatter interpretation, and DNA comparison are not being used to their fullest potential. Items of physical crime scene evidence are not always visible to the naked eye and may be easily overlooked so deliberate and methodical approach to collection and preservation of evidence is essential. Prosecutors have lost cases due to crime scene contamination; this could be prevented by simple and productive behaviors. The U.S. Supreme Court, in a leading case on physical evidence, stated:

Personal hygiene is a major part of your everyday life. It includes brushing your teeth, taking a shower, applying deodorant, wearing clean clothes, cooking your food properly, and washing your hands when necessary. There are many different types of hygiene and different ways of doing them. The types of hygiene are food and cooking hygiene, medical hygiene, and personal hygiene, there is even such a thing as excessive hygiene. Excessive hygiene may cause allergic diseases. Some parts of the body like the ear canal, or inside of the vagina are mostly better left alone for the body's own cleaning systems. Also, excessive application of soaps, creams, and ointments can adversely affect certain of the body's natural processes. For example,
