VAWA (Violence Against Women Act) protects women who are in an abusive relationship from enduring further dangerous conditions. However, there are some provisions a woman must make before being released from her rental obligation. She needs to get an Order of Protection and bring the copy to the office for her file. And, she must put into writing a request to be released from the lease. The property cannot necessarily banish the male leaseholder from the property since he still retains his lease.
As a landlord, I suggest you make all attempts to contact the male leaseholder by certified letter, any emergency contact address listed, email, phone, etc. and inform him that he is still obligated to the rental contract. You can tell him you intend to declare the unit to be abandoned within 48-72 hours (or whatever your company policy is) and that all remaining valuables will be held for 30-days. You can then, also, to be fully compliant, go through the eviction process so you can legally gain possession and change the locks. Since the woman theoretically satisfied her obligation to fulfill your policies, she is released free and clear and owes you nothing - if you released her from the lease.
Please consult your property's lawyer.
