You are to use your textbook, chapter 31, as a guide in profiling a criminal. You should also use the Internet, or books you have read in the past/are currently reading, to assist with devising your explanation of your serial killer. There are countless reasons as to why people kill people. Your job is to not solve the crime or evaluate the case proceedings.
