Why don't you just find the reason behind your expelling and take money from him? Then kill him and drop in the river. You know people afraid of death so he will give you all the money just make a good plan how to get them. Then kill him silently on night with knife and make it look like a robbery. Drop the body in the river and the water will destroy all the evidence from the body itself. Easy, simple and you do not have to bother about the dept and will even become rich. I quess this guy has a lot of money.
