Felon guest

[Bryan Caprioli]

I have a tenant that has a felon living with her that is not on the lease. My upstairs tenant is telling me that this guy is threatening her and her their child because she has complained about the noise. Everything to this point is heresay from the upper tenant, who has been a great quiet tenant ever since she moved in. So question is, what is going to be the best way to get rid of this low life/tenant? I will start by confronting the tenant about having a guest for longer than 2 weeks, but I would love to get this done quicker than that. Any help would be greatly appreciated.
