Theoretical Problem #2

You are extremely close with a high-profile drug dealer,
though you don't know how high-profile. You have known
him since childhood. He has never done anything out of
malice. You are awoken by a phone call just after 3 in the
morning. It is your friend. You can barely make out what
he is saying. You quickly get dressed and drive out to his
place. The door is locked. You knock continuously. You end
up having to climb in through a window. You enter the livingroom
and see about a pint's worth of blood splattered on the floor.
You call your friend's name. He answers from the bathroom.
You rush in and find him hovering over a female body that is
draped over the tub's edge. Her hair is matted with blood,
and her skin looks inhumanly pale. Your friend is completely
distraught. He keeps mumbling through sobs about how he
tried to save her, but she overdosed. You immediately go to
phone an ambulance. He rushes out and stops you, staring
frantically and repeating that you can't, he'll get caught, his business
associates will kill him, and that you have to help him get rid of her.
What do you do?
