Every year thousands of crimes are committed that involve a crime scene investigation, usually requiring the use of fingerprint powder or blue luminol. Australian Forensic Cleaning provides clean up and restoration of properties and vehicles that contain luminol, fingerprint dust, blood and other biohazard pathogens that may be associated with crimes and trauma.
If you are responsible for cleaning or restoration of a property containing these chemicals, it’s important that you hire a professional company like Australian Forensic Cleaning to perform the restoration. Any biohazards that may be found in the car or property can be spread through the use of these chemicals. Even trace elements of blood, if not properly removed and sanitised can cause potential dangers to your health for weeks after the clean up is performed.
What is Fingerprint Dust?
One of the oldest, most common and most readily available methods for the development of latent fingerprints is that of dusting a surface with a fine powder of contrasting colour. The use of powders depends on the object upon which the search is being conducted. Fingerprint powder is applied at the crime scene on smooth, non-absorbent surfaces and, in general, only to objects that cannot be transported back to a laboratory. The powder adheres to the humid, sticky, or greasy substances in the dormant fingerprint deposit.
Most black fingerprint powders contain rosin, black ferric oxide and lampblack. Many also contain inorganic chemicals such as lead, mercury, cadmium, copper, silicon, titanium and bismuth.
What is Blue Luminol?
The search for the presence of blood at a crime scene is normally done by close visual examination. The possibility exists that blood may be present in amounts too little to see with the unaided eye, or that the blood at the scene had been “cleaned up” prior to arrival of the crime scene team. Investigators can take advantage of the luminol reaction to locate potential blood evidence that would be undetectable through visual examination. The light emitted in the luminol reaction is thought to result when an oxidizing agent, such as blood, catalyses the oxidation of luminol by hydrogen peroxide in a basic solution. The reaction is not specific to blood, however, as other agents such as bleach, certain metals, and plant peroxidases may also cause luminescence with luminol.
Comprehensive Crime Scene, Fingerprint Dust and Luminol Clean Ups
The scene left behind after the police have completed their investigation can be just as traumatic as the crime itself. After the burglars have come into and rummaged through your belongings and have torn your home apart, the police follow-up with their investigation. There is a high possibility they will use fingerprint dust or luminol to collect evidence. After they are done, they leave you to put your home back together again. The easy part may be straightening the pictures on the walls and putting items back where they belong. The harder part is removing the fingerprint dust and luminol the police leave behind.
