Tenant who's not paying rent wants to leave. They want to terminate early

[Rufaro Chirewa]

My tenant is late on rent, and I found out they may be a scam as they gave me a fake name. (just found out)

They reached out saying that they want to leave and we can prorate the deposit for the days they haven't paid rent, then we can return the remainder of the deposit. I would rather do this than go the long eviction route, if possible, as I also want them out.

I want to make sure that if I do this I am not breaking the law, and they can't come back to try and sue or mess with me. 

If this is possible how would we legally terminate the lease? I am okay with waiving the early termination fee, I just want them to go.
