How to get rid of a creepy stalker guy? o.e?

well, a little over a week ago this guy found me on facebook (i think hes a friend of a friend) and he keeps sending me gross messages about how he wants to do stuff with me and pictures of... well.. body parts.. and wont stop. i deleted his msgs and blocked him but he got my email and now he sends them there.. he lives in the same state i live in and im a little creeped out by this. any ways to get rid of him? thanks :D
