Before any crime scene cleanup crews can begin work, the police investigation teams conduct a thorough investigation and baggage and tag all evidence. However, while providing their scene remediation services, professional technicians are careful to look out for and preserve any potential evidence, especially anything that might be of use to the forensics teams.
After a successful robbery at a convenience store, the robber fled to his car and drove off. The injured clerk, who was bleeding profusely, called the police. Emergency response teams arrived at the store in minutes and quickly ordered an ambulance to take the clerk for medical help. The store clerk who was injured was able give detailed descriptions to police detectives. Police were also able review surveillance videotape. Death Scene Cleanup
After a thorough examination of the crime scene by the CSI team, a professional clean up company, called in by the police, begin to clean the mess left by the robbery. As they were cleaning the area by the counter, one of the technicians noticed a small speck of blood that had been missed by the police as it was so small. Apparently, the robber had scratched himself on a metal appendage attached to the counter when he drew his gun.
Police detectives were notified of the discovery. One of the cleanup technicians showed it to the police. As this company frequently conducts suicide scene, meth lab, odor removal and other death scene cleanups as well as blood and trauma scene cleanups, they have experience working with police and identifying substances.
The blood was tested for DNA by the police and the samples were compared to those in the county jail. A previous defendant whose photograph matched the image in the convenient store's video footage was identified. An address for the man was found at the courthouse and the perpetrator was arrested and convicted.
While this is not a common occurrence, one of the primary qualifications necessary for trauma scene remediation work is an attention to detail. It is not the same as janitorial services. Professional biohazard cleaner teams are tasked with eliminating potential hazards from blood and bodily fluids, wherever they happen to land. For this reason alone, these cleanup teams are required to thorough and pay special attention to details. However, if it a source of great pride whenever something like this happens and the team is able to assist the police in their investigation.
