How to get away with murder: leaving behind no traces of blood.

"Do NOT use bleach," says Biohazard PRO, a Massachusetts crime scene cleanup company who says that bleach is not as effective as it is suggested.

Although the title of this blog seems like bait, it is not. Below you will learn as the title describes; the basics of what it takes to make blood undetectable to CSI bio detection tests-

"Criminal investigations begin with a search for clues. Teams of investigators arrive at a crime scene armed with special fact-finding gear. They look for standard evidence like fingerprints, footprints or blood at the scene of a crime.

But scientists recently discovered something troubling. Some new household cleansers can remove all traces of blood. If criminals simply use these products to clean up after themselves, police may have a hard time gathering evidence.

To get at particularly stubborn stains, like an accident from your pet, your parents may use one of these new products called “oxy” cleaners. These cleansers use oxygen and water to attack stains, including blood. Some of the ads claim to clean “over 101 stains on multiple surfaces.” That sounds good, but scientists have identified a downside to that much cleaning power.

The oxy cleaners even go beyond getting rid of visible stains. Usually detectives’ gear can find traces of blood that are invisible to the naked eye. But these oxy cleaners make even the invisible traces of blood unrecognizable to the most common blood-detecting tests.

The three standard tests for picking up blood rely on a protein in the blood called hemoglobin. This protein loves oxygen. In the body, it's hemoglobin's job to grab onto oxygen and carry it from the lungs to the rest of the body. But the new oxy cleaners flood a blood stain with a lot of oxygen. Once the protein gets its fill of oxygen, it won’t even bother to snatch oxygen from the investigators’ blood detecting tests. This means these tests will come up negative.

When you scrape your knee, a nurse, parent, or coach may rub it with hydrogen peroxide. Hydrogen peroxide contains hydrogen and oxygen and helps stop the bleeding. The chemical causes oxygen that looks like foam to rise to the surface of your cut. There, too, hemoglobin in your blood seeks the oxygen in the hydrogen peroxide.

Common blood detectors rely on the same kind of reaction between blood’s oxygen and hydrogen peroxide. The detectors contain hydrogen peroxide that reacts with hemoglobin in a blood stain. When hemoglobin grabs some oxygen, the blood detecting test gives a positive result. Depending on the chemical in the test, a positive result might glow or turn pink.

In the name of science, a group of researchers decided to test the oxy cleaners. The scientists made their own fake crime scene by using samples of their own blood to stain a couple pieces of cloth. The team put five drops of their own blood on a soft cotton cloth, some jeans and a towel.

Then, the researchers washed part of each cloth sample in “Neutrex,” an oxy cleanser. The team thought the oxygen in Neutrex would be released upon contact with water. The large amount of oxygen would cause the hemoglobin to work overtime. This would effectively clean up the blood, but also tire out the hemoglobin so that it wouldn’t react with the tests. The scientists also washed other samples of blood-stained cloths with a traditional cleaner. All the samples were then left to air dry.

The cleaners worked as the scientists suspected. The cloths washed without oxy cleaners looked clean, but the three tests still picked up the blood traces. But after an oxy wash, the other sample fabrics looked spotless to the naked eye, and also came up clean on the blood tests. The difference: The oxygen bath given to hemoglobin exposed to the oxy cleaners. After spending time in the presence of that much oxygen and trying to snatch it, the hemoglobin couldn’t react with the investigators’ tests.

Despite the study’s results, this cleaning possibility doesn’t mean that bloody crime scenes are a thing of the past. “People committing violent crimes often don’t have time to clean up; they leave a lot of stuff behind,” says Walter Rowe, a forensic scientist, someone who examines evidence in a legal case, at George Washington University in Washington, D.C."

Definition of Murder: the unlawful premeditated killing of one human being by another.

Let it be strongly suggested that you should NOT, under any circumstance, murder anyone. This blog was for informational and scientific purposes only. Not only is it illegal but it is immoral. Committing this violation of human rights can result in life in prison and severe psychological damage.

What are bloodborne pathogens?

Here is a brief explanation made by OSHA some of the strict regulations and standards required by every biohazard remediation company:

"Bloodborne pathogens are infectious microorganisms in human blood that can cause disease in humans. These pathogens include, but are not limited to, hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV). Needlesticks and other sharps-related injuries may expose workers to bloodborne pathogens. Workers in many occupations, including first responders, housekeeping personnel in some industries, nurses and other healthcare personnel, all may be at risk for exposure to bloodborne pathogens.

What can be done to control exposure to bloodborne pathogens?

In order to reduce or eliminate the hazards of occupational exposure to bloodborne pathogens, an employer must implement an exposure control plan for the worksite with details on employee protection measures. The plan must also describe how an employer will use engineering and work practice controls, personal protective clothing and equipment, employee training, medical surveillance, hepatitis B vaccinations, and other provisions as required by OSHA's Bloodborne Pathogens Standard. Engineering controls are the primary means of eliminating or minimizing employee exposure and include the use of safer medical devices, such as needleless devices, shielded needle devices, and plastic capillary tubes."

Be sure to look for the full OSHA bloodborne pathogen regulations post to read all the details word for word that every crime scene cleanup company or biohazard remediation company is required to follow.

Who cleans up after death or other trauma when emergency responders leave?

Crіmе ѕсеnе сlеаn-uр involves рrореr collection аnd disposal of bоdу fluіdѕ such as blood, brain matter, skull fragments, and other remains. This jоb can оnlу be done рrореrlу by certified experts that have been extensively trained. Cоmраnіеѕ whо offer these kіnd оf services рrоvіdе trained tесhnісіаnѕ thаt wіll do the work fоr уоu so that you are not held psychologically or legally responsible. Mоѕt of thеm also have mеdісаl or emergency bасkgrоunds which mаkеѕ it еаѕіеr fоr them to be exposed such graphic situations since they may have had pleanty of other encounters dealing with situations like this. But although those are good qualities, it takes much more specialized and regulated training when it comes to сlеаnіng bacteria, communicable diseases, blооdborne раthоgеnѕ, and оthеr оrgаnіѕmѕ thаt may pose a dаngеr to people's health.

Whу a sympathetic nature? Bесаuѕе сrіmе scene сlеаn uр is a lоt different frоm cleaning any other type of scenario. Sometimes, fаmіlу members оf the dесеаѕеd are still рrеѕеnt while the сlеаn-uр іѕ оссurrіng. Thе сlеаnеrѕ muѕt be able to complete thеіr jоb whіlе being ѕеnѕіtіvе tо the state of the family whо has еxреrіеnсеd a loss. Therefore, crime ѕсеnе cleaners muѕt separate themselved from their work of cleaning mеѕѕу and graphic incidents and remain compassionate at the same time for when they are communicating with the customer.
