Legal studies is a good path if you are interested in law :)
Not only that, but you can use it for public administration, public affairs, business, and political science. It is not the easiest, but it is worth it if you are interested in anything of the above. Studying law is as hard as you make it. In my opinion, it is definitely worth it due to the fact that its a great stepping stone for high level government positions.
I would ask what has happen between the two in the last month. What harsh stuff the murdered person has done. Ask the personality of the victim. And see if there is negative responses in his answers.
