Question

Let’s use the example from above regarding the carpet fibers embedded in the cuts on the body of the dead female found in the field. The main suspect is her boyfriend. He has a history of domestic violence charges against her, with the most recent one being reported with a month of her murder. The carpet fibers in the body are analyzed and their actual make-up is comprised of a specific proportion of nylon and polypropylene, and the chemicals used to dye the carpet are identified and their proportions are also known. When compared to carpet fibers in the boyfriend’s house, they are an exact match. Does the information from the test results confirm that the carpet fibers in her cuts are in fact from her boyfriend’s house? Why or why not? Fill in your answer and reason in the box provided here.

Answer 1

Answer: Yes, the information from the test confirms that the carpet fibers found in the body are from her boyfriend's house. The specific composition of chemicals and proportion in it are proved to be an exact match to the carpet in his house, and this kind of scientific information cannot be invalidated. Therefore, it is possible that the boyfriend himself was the murderer, but what is known for a fact is that the girlfriend was in his house when she was killed.
