What Does a Forensic Nurse Do?? - India
Forensic nursing bridges the gap between health care and law enforcement. It’s the application of the science and art of nursing to criminal and civil investigations and legal matters.
Forensic nursing is different from other types of nursing education because students acquire the in-depth knowledge and skill that interfaces nursing with the law, law enforcement, forensic science, mental health and the health care and judicial systems. In addition to learning basic theory and concepts, students are introduced to the real-world aspects of forensic nursing and interacting with the law enforcement and legal systems.
What is the work environment like for forensic nursing careers?
As far as patients go, forensic nurses can work with victims of rape, sexual assault, domestic violence, pediatric trauma, as well as victims of other violent or traumatic events.
As far as patients go, forensic nurses can work with victims of rape, sexual assault, domestic violence, pediatric trauma, as well as victims of other violent or traumatic events.
Forensic nurses often work with hospitals, prisons and law enforcement to collect and document evidence, and act as aids in a crime scene investigation. They can also provide expert testimony in court helping the police to catch and convict criminals.
Why would someone want to work in forensic nursing?
Many students in forensic nursing work full time as emergency room, critical care and/or intensive care nurses. They’re already working with victims and want to be able to assist them in a legal way.

What are some of the challenges of a forensic nursing careers?
One of the challenges of forensic nursing is to stay focused and calm in a fast-paced, chaotic and often upsetting environment. Forensic nurses need to be able to comfort victims while gathering evidence.

Forensic Serology. Description, Education, Case Study
The job of the serologist begins at the crime scene.A forensic serologist extracts DNA evidence from bodily fluids connected with a crime, including blood, semen and saliva. This identifies victims and possible suspects and can be the cornerstone of a criminal conviction.
Tests are also done to determine the blood type and Rh factor, and to figure out which antigens and antibodies are present. These new techniques help to determine whether the blood belongs to any particular suspect.Forensic serology can also be used on other bodily fluids as well. By testing the fluids it is possible to determine that a suspect is definitely not the culprit in the crime, and to give an idea of what type of person might have committed the crime.
Despite how well the crime scene may get cleaned up, even the finest trace of blood can often be detected and further tested. It is often the case that while the perpetrator may scrub down the obvious places, he can still miss between floorboards, under pipes, and inside drains. Merely by pouring water on some tiles at a murder scene and pulling them up wherever the water flowed beneath them, one detective found the only existing trace of the crime--blood.
TOXICOLOGY AND SEROLOGY:
Forensic serology also looks at toxicology factors for evidence of poisoning. It is also used to determine if wildlife has been poisoned.
Presumptive tests:
The Kastle-Meyer Color Test uses a solution of phenolphthalein and hydrogen peroxide on a piece of filter paper, and when blood of any quantity is present, it turns pink. However, it also turns pink in the presence of potatoes or horseradish, so care must be taken at the scene.
Sometimes microcrystalline tests are also performed. The two most often used are the Takayama and Teichmann tests. Both add specific chemicals to the blood to make it form crystals with hemoglobin derivatives. These tests are also sensitive to other materials that may be present in a bloodstain.
Education
- People with a bachelor's or graduate degree in forensic serology or a related field have learned to apply biological science to criminology, including the areas of genetics and DNA analysis, molecular biology, pathology, and metabolic biochemistry. Most forensic serologists work for law enforcement agencies and crime laboratories.
OJ Simpson & Forensic Serology
On the night of June 12, 1994 neighbours were woken by a dog barking. The barking led them to the scene of a bloody crime. Laying in a pool of blood was a woman named Nicole. Near Nicole was her friend. When police arrived and took a closer look, they found that the attack had left Nicole nearly decapitated.
There were many pieces of evidence at the crime scene. Not only was there a blood pool, but there was also a hat and a bloodstained left-handed glove.
After the police made their report, they set off "wake-up calls" to the homicide detectives. The police and homicide detectives met at the scene of the crime and then drove to Simpson's house. While "buzzing" the intercom a detective noticed blood on Simpson's car. Then they saw blood drips going from the car to the front door of his house. More evidence, which was recovered from Simpson's house/bedroom, consisted of a sock belonging to the victim, Nicole, who was Simpson's ex wife. Another piece of evidence was a right-handed glove, retrieved from Simpson's car. It too had blood on it.
Forensic Serology was applied in this case when it came to all of the blood evidence. The blood from the sock was tested and showed that the blood belonged to Nicole. Blood from the right-handed glove was from Simpson and both the victims. The blood trail leading from Nicole's home, to Simpson's car, and then to Simpson's house, in itself, almost proved his guilt. But Simpson's legal team was one of the best and, this ending up being a nine-month long trial, Simpson was later cleared of the murder.

FOOTWEAR EVIDENCE IN FORENSICS
Footwear track evidence can be very instrumental to the successful conclusion of a criminal investigation.Detailed examination of footwear impressions can help to link a specific piece of footwear to a footwear imprint as each shoe will have unique wear characteristics.
Photographing Footwear Evidence
Written by Dwane Hilderbrand
Taking quality examination photographs
When making quality examination photographs of the evidence prints, be sure to use the same numbered marker you used when you were showing the relationship of the print to the scene. In order for a footwear examiner to perform a quality examination, high-quality, close-up photographs are required. Since footwear evidence can come in two different forms—prints and impres-sions—the techniques of photography are slightly different. This can be easily obtained with a little time and patience. There are many types of cameras that are being used for crime-scene photo-graphy, ranging from 35 mm and 4 x 5 film cameras to digital cameras.
After the selection of the camera and the film or digital media, you will need to select an appropriate scale that will be present in all the photographs. This is very critical in order to allow for enlargement from the negative or image to make an exact duplicate of size (1:1). When no scale is utilized in the photograph, the examiner has no idea what the size of the real impression is. It then becomes difficult for the forensic photographer to print 1:1 scale photographs for examination purposes.
Types of footwear evidence
Footwear evidence can come in at least 3 forms, footwear outsole impression evidence, footwear insole impressions and footwear trace evidence.
Footwear outsole impression
Footwear outsole impressions are impressions left on an object that was caused by contact with a piece of footwear. These can left on the ground or raised surface by persons treading over it, left on doors or walls by persons attempting to kick or climb over a wall or even left on other persons after being kicked or stomped on.
Latent footwear outsole impressions:
Latent impressions are caused impressions that are not easily visible to naked eye. Such prints can be on many different surfaces such as floor tiles, concrete or even carpet. Latent impression may not be easily visible to the naked eye and its detection may require the use of additional specialized light sources such as portable UV lighting. Recovery typically includes photography as well as lifting with “gel” or “electrostatic” dust lifters.
Footwear Insole imprints
Footwear insole imprints are imprints left in the inside of footwear caused by contact from the person’s foot. Analysis of the insole imprints can be used to link a person(s) to a piece of footwear.
Footwear trace evidence
Footwear trace evidence is trace evidence that is recovered from footwear. Types of trace evidence that could be recovered include skin, glass fragments, body hair, fibres from clothing or carpets, soil particles, dust and bodily fluids.
The study of this trace evidence could be used to link a piece of footwear to a location or owner.
Detection of footwear evidence
Detection of impression in ambient lighting
Detection with forensic light sources
Detection with electrostatic lifting devices
Detection with chemical enhancement

Forensic Saliva Analysis
Body fluids, whether excreted or secreted, help our forensic experts compile detailed reports on sexual assaults, death, and the identification of attackers among other things.A forensic investigation can involve the analysis of body fluids, including saliva, for evidence of toxins and both prescription and illicit drugs.Saliva can be of forensic significance because traces of drugs that are circulating in the body can be present in saliva. The composition of the saliva accurately mirrors the proteins that are present in both the blood and the urine. Thus, testing of saliva, which is easier and less obtrusive than obtaining a blood or urine sample, can be used to reveal the presence of prescription and illicit drugs.
Saliva is presented as an alternative matrix in the establishment of drug abuse. The ultimate salivary concentration is determined by the route of administration, the salivary pH, the degree of plasma protein binding,and the physico-chemical properties of the abused drug. Since the saliva/plasma ratio can exceed 1, saliva might be a better analytical tool than blood during roadside testing of potentially intoxicated drivers
Virkler and Lednev add that Raman spectroscopy has great potential as just such a non-destructive tool. In 2008, the team reported that it could be used to identify bodily fluids at a crime scene but those experiments were carried out with just a single sample of each type of fluid. Now, the team has extended the work significantly to investigate the potential for spectroscopic differences among different “donors” of the same fluid.
The researchers have used near-infrared (NIR) Raman spectroscopy to obtain spectra for pure dried human saliva samples from several donors in a controlled laboratory environment. By applying principal component analysis (PCA) on the spectra they demonstrated that dry saliva is a particularly heterogeneous substance. However, the Raman spectra can be described as being a linear combination of a fluorescent background and three spectroscopic components.
Forensic Preliminary Testing for Saliva (amylase)
Phadebas tablet method
1. Place 50 ul of each described dilution from above into a
test tube.
2. Add 1.0 ml of water, and ¼ Phadebas tablet (cut with scalpel
or razor blade CAREFULLY). Add the ¼ tablet using
forceps, NOT fingers to handle/cut the tablet.
3. Vortex to mix thoroughly.
4. Incubate at 37C for 30 minutes.
5. Add .25 ml of 0.5 M Sodium Hydroxide to each tube to stop
the reaction.
6. Centrifuge for 5 minutes.

LATEST!!- New Forensics Tool Can Determine a Person’s Age from a Spit Sample
Researchers at UCLA have figured out how to determine age to within five years from nothing more than a saliva sample. The method relies on a process called methylation, which is a chemical change to one of the four building blocks of a person’s DNA. Methylation changes as our bodies grow older, contributing to age related diseases. In extracting DNA from saliva samples from more than 100 test subjects, the team found that it could zero in on a person’s age within five years by looking at just two of the 3 billion blocks that make up the human genome–such is the strong correlation between methylation and age.
