I chose forensic investigation because I want to do something fascinating and perplexing and dynamic. What I like about forensic investigation is that it brings physics and chemistry and biology together in one place like blood splatter patterns, the identity of an unknown suspect and examining trace materials which interests me because I currently do chemistry and physics in my A-levels. I love solving a puzzle and I think of forensic investigation to be like that because every crime scene is unique with different situations every time which transforms science to be mysterious than ordinary science. I understand a forensic investigation is a significant role in policing and justice system without it the incarceration of criminals would not be possible.

When I was younger in 2011 there was a TV series on TVB channel (Hong Kong) called Forensic Heroes, which influenced me to research more about forensic investigation. It was the first time that I have experienced anything incredibly surreal at the time on the screen which made me enjoy the show and propelled my curiosity for forensic investigation but popular media generally cut the corners and creates a fictional image to the viewer that catching the criminal is simple. That is why my inquisitive mind wants to know more about the techniques and procedures used in the real world. Just trying to get into the mind of the perpetrator and understanding the logic of their crime such as what drove them to do this is truly enlightening.  I am also aware that forensic investigation involves more than lab work, there will be crime scenes to attend which can be devastating and present forensic evidence to a courtroom will be necessary. I always dreamt of helping law enforcement by devoting my time to find forensic evidence to prove, a crime has been committed, corroborate a victim’s testimony and establish the identity of persons associated with the crime.

To improve my understanding of the course, I have been watching a documentary series called Forensic Files which allowed me to understand how forensic science can unravel violent crimes and mysterious accidents. For example, I did not know DNA can be found as tiny as a single cell by removing from saliva, hair, blood or skin. Afterwards, it is taken to the lab to find a distinctive fingerprint or a repeating pattern. Once the samples of DNA match to the DNA profiles that are stored in a database it verifies that the DNA came from the same individual. In addition, innovative ways are being introduced which may even allow police to produce DNA profiles at crime scenes and increase profiling speed in the lab. Many pieces of evidence can be found in the deceased, such as examining for injuries signifying violence and cause of death. The body’s decomposing state can signify when the victim died which is simple to estimate if it is between 12 to 24 hours of death. If more than 24 hours, indirect evidence must be used for example chemical methods or insects.

Taking chemistry has further improved my analytical and scientific technique skills through lab experiments and practical reports. I took maths which enhanced my problem-solving skills by tackling questions when the question or solution is not recognisable. Whilst the study of physics has enriched my inquisitive mind.

I work at my family’s takeaway where my punctuality, reliability and honesty is tested as I deal with customers that either walk in or phone to order their meal and handle their money which expands my communication skill. In addition, I provide the quickest route for delivery drivers so that develops my organisation skill and being quick is vital such as restocking ingredients, so the chefs are ready to cook the meals instantly.

I believe that this course will challenge my intellect and evolve my skills that I need to pursue in an analytical or investigative career since forensic investigation covers many different areas and I would like to keep my opportunities open.
