Deposit returns for inherited tenants?

[Dustin Beam]

Hello Beautiful people of BP,

So I had 3 tenants vacate at the end of last month.  One was evicted,  so no deposit return there,  the other two left after their leases ended.  

One of the two left the apartment disgusting.  She did not take all her property out,  nothing cleaned,  animal feces and feces stains on the floor,  carpet ruined.  I do not intend to return the deposit to her. 

The other tenant actually did a good job cleaning,  but living room carpet has big dark spot in it,  I assume it can't be removed.  But more to he point,  the main entry door jamb is trashed. So is the upstairs bedroom door jamb,  and the main floor bedroom door is jacked to the point it can't close. This tenant has inquired about the deposit return,  and did clean it well (carpets excepted). For the record,  lots of pics were taken. 

So my question is how to handle the last tenant. I have no proof of the condition the apartment was in when they moved in.  I can't believe the doors were in that bad of shape. I've heard from other tenants that her and her boyfriend fought often and loudly and I suspect that's how the doors got damaged. If I pay someone to fix those doors,  that alone would probably take the deposit.  

How would you handle a situation like that?
