post 24 hours notice to enter (assuming your state requires 24 hours. some require 48 I think). then go in. if the locks have been changed, drill them out and replace them. bill this to your tenant. you should also stress to the outgoing tenant, that the illegal tenants possession of the property works the same as if the tenant never left and the original tenant is jointly responsible for anything the illegal occupant does. stress that you cannot force him out without a lengthy eviction, but him and his brother should do everything in their power to get him out ASAP. continue your eviction process, and do not stop until you have full possession.
