She showed two examples from the case images, the left one looks like a vehicle passing over the body and the right one is looking like a suicide case but our speaker strongly suggests to not get dependent on the facts that are visual and never let your presumptions to guide you while investigation because mostly the crime scenes are all about what is not visually depicting and here comes the role of the forensic investigator to thoroughly observe the whole scenario, check for every detail twice and collect and analyst evidence accurately and precisely.
Review of Los Angeles County Medical Examiner-Coroner
The investigating team doesn’t just contain investigators, but also a whole lot of other people. Investigators don’t work alone while investigating a crime scene.
A whole investigative team plays the backstage role in the culmination of an investigation. The team could involve detectives, first responders, criminalistics, witnesses, crime scene investigators, law investigators, medical professionals, or anyone who brings information to the particular case because not one person can do it all. The team could vary depending upon the nature of the crime scene.
As per a Los Angeles medical examiner's concern, she told that the coroner at Los Angeles is the busiest person who covers over 5000 square miles for investigation per day and conducts over 7500 autopsies per year.
Mostly in the medical examiner offices, they do not have a budget for having their staff for specific tasks regarding a case such as photography, evidence collection, or autopsy investigation. but in Los Angeles, there has been a team of corner personal which includes investigators, forensic attendants, criminalistics, photographers, evidence custodians, and autopsy technicians and other special and expert officials as per the requirement of the case.
Each coroner’s office deals with the cases on natural causes, buried bodies as well as an unnatural crime scene.
Case Study
She discussed a case of workplace death accidents of an employee of a wood chipper company. Before getting into the case details she explained about the working and instrumentation of the wood chipper which has been the main culprit in this case.
The main function of the wood chipper is to take the trimmed branches from the feed tray and pulverized them and shrugged out into another collection device.
In this case, the wood chipper was a mobile commercial machine mounted on a frame on a single axle commonly used for tree trimming.
The feed tray of this wood chipper was 55 inches with the Chute of 36 inches and a feed wheel that rotates in the direction of the operator.
It also has steel teeth engage with the material and the debris is expelled through another chute (a big truck, was the collection device in this particular case).
Case Background
Two employees of a wood chipper company were employed to clear a locality of the tree debris and branches. One of them is sitting high on top of a tree trimming the branches and the other is near the machine feeding it with the trimmed branches.
All of a sudden the worker near the machine disappeared and blood and tissue were seen at the mouth of the wood chipper. In the inception stages, it was prematurely assumed that the worker got sucked into the wood chipper without looking at any evidence.
The debris were collected from the wood chipper but it posed a challenge.
Challenges Encountered
• Other teams of experts to be called upon, to take apart the whole wood chipper.
• Uncertainty and unawareness as to the collection of such kind of evidence as all the tissue were outstretched and pulverized.
• Whether evidence obtained will be recognizable or not.
• Getting larger pieces of evidence to a processing area.
Strange Remains!
Upon detailed investigation and sifting through the tissue samples, shreds of clothing were obtained. One such shred contained a unique account number belonging to the employee under question. This proved to be an important piece of information. Also, boots with intact feet were obtained from the drum of the wood chipper, along with underwear.
These were further verified by the wife of the employee.
The worker is then declared dead upon identification through the unique account number, boots, and underwear found inside the wood chipper.
The wife of the deceased filed a suit on the wood chipper manufacturing company. The company claimed that the worker must have fed wood from the front instead of the sides of the wood chipper.
However, the wife’s team claimed that due to the lack of any safety measures and a fail-safe system, the unfortunate incident occurred.
Judgment was passed in favor of the wife, that failure to install a safety system in a wood chipper would have eventually caused such an accident.
Conclusion
No matter how big or small a role a person plays in the investigation, it should always be thorough. Whether, photography, evidence collection, sketching, report writing, etc. all should be carried out thoroughly without leaving a stone unturned. A thorough investigation will be of help in the court of law.
Personal Note
The session was full of information and a detailed description of a very interesting case where even though the story can be assumed but the assumption has not been overlaid to the detailed investigation which is very important to reach out to a certain conclusion. For a more detailed view of this case, I would recommend visiting the playlist for the International Lecture Series of SIFS India from 2020 at our YouTube Channel, forensic365.
