Gunshot Residue And The Effects on Your Health

The Curious Case of Nancy Ann

Magnum GunshotIt had all the hallmarks of a typical gun-fueled homicide. Police found the appropriate gunshot residues matching a .45 magnum (which by the way, leaves ALOT of dust). The blood splatters across the wall accurately place and angle of shooting, and give a correct body fall placement. Although the time stamping of the blood placed time of bullet entry, thereby the bullet exit, at approximately 8.45pm. The bullet missed the cerebral cortex by 1.7cm but still penetrated the skull.

 

Amazingly, Nancy Ann did not die on the spot. Coroners placed her time of death at closer to 11pm.

 

How was Nancy Ann able to keep her brain alive for more than 2 hours? The secret lies in the autopsy report, which indicated Nancy Ann had taken twice the standard dosage of Armodafinil, or generic Nuvigil, a drug aimed to cure excessive daytime sleepiness.

Examining a Gunshot Residue

blueswabThe importance of knowing the appearance of gunpowder is very important. It is designed to its ability to have a quick burn and has a rapid production when it comes to its expansion of the gas that is confined in the space. Knowing more about the effects of gunshot residues is very essential when it comes to bringing out the best of what a gun can give.  There are indeed many ways for you to be able to classify a gunpowder, here a just three ways:

Regressive burning gunpowder – this comes in a variety of forms such as sticks, balls, flakes that can affect the surface as it decreases continuously while grains are consumed.

Burning neutral gunpowder – it is perforated and surfaces are burned wherein its areas are constant.

Progressive burning gunpowder – in comparison to single perforation, this has a multi-perforation that gives out a burning surface as this gives an increase continuous grains which are consumed.

Take note that there are even gun powders that are not burned as you can recognize different colors, shape and even the size of the grains.

 

When it comes to examining a gun residue you need to be definite with the details that you are to impart especially when you are investigating a crime scene. Every gun residue matters to the series of the events. It is important that you able to identify the type of gun residue that is used accordingly by the said situation. There are two types of residue and that is the organic and inorganic.


Difference between the organic and inorganic

Inorganic – this consists of chemical elements such as barium, lead and antimony. If you are going to compare it with the organic gunshot residue that may come primarily with derived materials that is found at its propellant. Most of its compounds are classified in its explosives, which are based on the composition of each chemical. Nitroglycerin is considered to be an explosive. There are many ways that gunshot residue can be found in different areas, such as at the skin or clothing, who basically fired the gun and have made an entrance towards the skin making a hole.

Organic- this can be detected in several hours through the use of hands despite the losses that has evaporated to the air and has permeated the skin as well.

Detection of the gunshot residue – based on Analytical and its qualitative. These two methods are commonly used to collect any adhesive stub. Aside from these, there will be other evidences to be taken as well, such as takfor111ing of pictures. It is important that you are able to deliver the exact contents when it comes to evidence and case presentation. There are other ways for a team of crime scene professionals to get more evidence and this can truly help in the extent of making it everything visible during in the time of court trial appearances.

What Are The Effects Of A Gunshot Residue

2000px-solidrocketmotor-svgThe gunshot residue is divided accordingly to categories wherein the result are more precise by the time case presentation is needed in the court trial.

 

First category

The pattern of the gunshot residue is found on the garment and the ammunition and firearms are basically questioned first and recovered as well. This would mean that everything is questioned prior to what you want to know more about the situation. It is important that every details counts and recorded. All the things that you have collected during the first twenty hours of the crime up to the succeeding days should have a focus. Moreover, as you see a residue over to a garment, it is noted that you need to take it as an evidence. Make sure that you are able to document all the necessary details to every result that you have gathered. If you are going to report regarding the details of what have seen on the garment, it should be based on the gunshot residue.

 

Second category

The pattern of the gunshot residue is found on the garment with its ammunition and firearms are not recovered- this is basically a pattern in which there is a near gunshot in which the clothing 2338051_1445995461088may have a hole from the bullet and at the same time it’s almost like a missed hit. This also most likely is a physical effect on the person who almost died on a gunshot such as in shock. The effect on this gunshot turns out to have more impact compared to the first category. It is known that firearms can tear down not only things that can easily be broken, but also the clothing. The gunshot residue has created a big impact when it comes to the bullet hits either a soft or hard surface. The chemicals found in the gunpowder can easily be melted. This would also mean that the gunshot powder is very visible to the naked eye.


Third category

It has no result of gunshot residue and it only has a series of trace amounts that should be found on the garment- this is not easily seen by the naked eye and most of the residue in this case are barely to nothing at all. If you are to assess a crime scene with this type of category, you will see a bullet entrance right straight across the chest making a hole within the area. You will find its consistency as to how each are deposited in an intermediate variation range of the gunshot residue.

What does it mean if you can not find any bullet residues at which it has created a hole?

This only means several things, but this is broken down into the following:

headerimage-ballisticsFirearm is too distant in which it didn’t able to reach the garment.

There is an object distance between the firearm and preventing the garment to have the residue stains that will reach the clothing.

The residues are removed with handling it severely with heavy bleeding and others

Identifying Gunshot Particles of A Single Gunpowder

 

There are many ways to identify gunshot residue wherein only skilled professionals can do the job. If you are new to this particular level, you need to observe first the people who are mentoring you in becoming one of the finest forensic members and or investigators in a crime scene. It is important that you are able to identify gunshot residue or particles that happened in a crime scene. However, this particular job needs a lot of full time attention when you are going to investigate. You need to be SMART in doing all the tasks

 

Here is a method wherein you can fully adjust to the extent of the case and identifying gunshot residue.

 

Specific – Part of the assessment is the specifications of every movement of the entire case scenario. It is important that you are able to deliver this in a concrete task. The method of every case is focused mainly on the evidence that is collected by the investigator as per where the crime scene took place
.

Measurable – As soon as you have the case ready for further investigation it is important to set goals in aiming to solve the situation. Cases are given full extent of service when it comes to investigating both on the scene and the people that was involved. There should be enough evidence to suit a case that through a gunshot residue.

 

Attainable – Another factor for you to identify gunshot residue is done every time there is a shooting case scenario. This will clearly give a much evidence once it is confirmed by the investigators.

gsr-icon2

Realistic – Of course, cases like these are for real and should not be taken less or even for granted, quick action should be followed immediately. However, there may be instances that a prolong rescue is made, investigators should take note on the specimens that can be found on the premises of the case scene and if there are gunshots involved, it is important to estimate the credibility and time frame as to how fast things had happened.

 

Time-bounded – The smarter the test, the more you are able to figure out the events of the scene, the heavier the case of the crime. This does not only involve one gunshot; you’ll see the wasted elements. A part of the testing should include the following stabilizers and the plasticizers.

 

Smarter testing created a more diverse element or component in finding the residue of gunpowder. You must also understand that when an opponent fires the gun, there are gun powders that gsrproduces an enormous pressure of gases that are most of the time present on the hands of the owner of the gun.

 

However, there would always be a time wherein being specific in investigating a gun powder residue are basically modified which leads to a more prolonged investigation. One thing that you need to be confident about is for you to have a good structured report while you are still doing the case. Determining and identifying the case should always resolve a more serious way in taking out resources from the crime scene.

Tips in Removing Gunshot Residue

tn_h2000168looking_for_gunshot_residue_46In order to detect if a certain person has fired a gun weapon, the police uses a technology that checks the gunshot residues on the suspect’s hands, clothes, arms, pants and even hair. Once you have fired a gun, the lead particles will eventually be scattered around your body and there is no way that you can erase the evidence because it is just almost everywhere. However, if you really wanted to remove gunshot residue, here are some tips that you need to consider:


Avoid it getting to you

Technically, gunshot residues are very difficult to remove. The best way not to deal with it is making sure that you are covered with something when you fire the gun. In that way, a coat will serve as your protection from getting it into your clothes, you might want to wear some gloves too and if you can, hide your body behind a door or something. In that way, there is less gunshot residue that will stick around you after you have fired the weapon.

 

 

Urinate on your hands

You should know too well that a simple shower will not remove the gunshot residue, so urinating on your hands can also be your option. Though there is no scientific explanation that proves that urine can really remove the gunshot residue, you might as well give it a try because it seems to be effective on other people.


Shower thoroughly

After you have discharged the firearm, make sure that you escape and then go somewhere where you can dispose your clothes. Even burn them in order to make sure that there are no traces of evidence. After that, take a shower and rub every inch of your body thoroughly. As much as possible, avoid using mild soaps and shower gels because it cannot help you in removing the gunshot residue on your body. Put some lotion on, wash your hair thoroughly because it can even get into your hair and even if it gets red and itchy, scrub it as hard as you can. There are times when these lead particles seep into your pores that is why you should make sure that you immediately take a bath right after you pulled the trigger.

36-6243-gunshot-residue-presumptive-test-kit-lActually, the best way to remove gunshot residue is not becoming a suspect. Do not just pull the trigger on your gun just because someone didn’t paid you their loan or you wanted to have revenge on someone. That is just so wrong in so many ways. While the fact remains that there are only few ways to remove a gunshot residue, you should just avoid touching and firing the gun. Most of the police nowadays will now depend on the gunshot residue to identify whether or not you are the suspect that they are investigating.

Gunshot residue is definitely hard to remove, but you can give these tips a try in order to see if it works on you too.

Facts About Gunshot Residue

svc_crim_gsrDuring a crime scene, everything is investigated and the entire affected premises should be kept to a minimal wherein only those who are authorized to do the task are allowed. This is strictly prohibited to outsiders who are not involved and even those who wants to do interviews, such as the reporters, are obliged to ask permission from the authorities to do an interview and a glimpse of a crime scene. There are many things that you need to consider when it comes to the different types of crime scenes and there are many types as well in investigating a crime scene. This takes a series of time to be able to come up with a solution of every crime that is under covered by an official.

Depending on the crime scene and the accessories that has been used such as a knife, an axe, perhaps a gun and its residue are collected to detect any finger prints that was hand held by the defendant and these are counted as an evidence in every crime scene. Anything that is involved are collected and can be used during presentations of evidences in the trial court.


Gunshot residue

In every piece that a detective and or other official that is handling the case, it is important to them to be able to analyze and come up with an analysis with the piece that was collected. Gun shot residues are most likely to be found in a crime scene. This can either be used by the victim or the defendant. The science behind gunshot residue is brought about the investigation that is in the process of analyzing how each step happened. This will enable one crime scene to open and lead to another until there is enough evidence of the crime. This also means that decisions are made accordingly, especially if it is found guilty of the crime done.

 

How is gunshot residue investigated

As someone pulls off the trigger there is an absolute reaction that will chain through causing it to strike the pin wherein the cap that is near the cartridge. When this happens the it will cause a reaction that will lead to an ignition of the gunpowder and as it is ignited there is an increase in temperature, thus pressure occurs immediately causing the the gun to fire the bullet out to its direct opponent. Elements such as the barium, antimony, and lead are the first elements in the gun that escapes out from the gun and form vapor that is called plume.

 

Finding evidence using the gunshot residue

gsrfig1-092712If there is an involvement of a gun, absolutely firing the gun is present in the scene as well either its a hit to the opponent or a miss hit. But the point of the investigation is the evidence that’s needed to be sought while solving an exposed evidence. Although there are other reasons to assumed the crime because it may have elapsed the time, the surrounding activity, there is an ammunition that was not good and many more.

There are scenarios wherein one or two particles are found in its analysis. In this type of crime scene there could be involvement of other resources such as nail guns, pyrotechnics and battery. All throughout the investigation other collaborations from other professional are also needed in order to solve a case and justice is given to the deserving. Such having laboratory work ups of the case, the evidence that was collected. A probative evidence is a process wherein there is no further thoughts about the case that is why it is still called a probative evidence.
