Peter has been found dead in his hotel room. Who could have killed him? What DNA evidence can you find at the crime scene and how can you analyse it? Can you find the murderer?
DNA evidence can be found at the crime scene in the form of hair, skin cells, saliva, and blood. This evidence can be analysed using a process called DNA profiling. This process involves extracting the DNA from the evidence and comparing it to a database of known individuals. If a match is found, then the individual in question could be the murderer. However, it is important to note that DNA evidence alone is not enough to prove guilt beyond a reasonable doubt. Additional evidence such as witness testimony, CCTV footage, and other physical evidence must be collected and analysed in order to determine the identity of the murderer.
