Drunk tenant problem

[Jason Vermeulen]

All, 

I'm curious what you would do in my situation.

Tonight one of my tenants got drunk and started fighting with her boyfriend. It ended with physical violence and she hit her boyfriend and he got a busted head. the cops were called and they took her away. Likely neither will post charges.

She is on a month to month lease. Im planning to terminate her lease. Would you do that in my case? How should i go about terminating her lease? Other than this situation she has been nothing but a good tenant. 

thanks in advance
