Tenant Wants to Terminate Lease After 1 Week

[Brendan M Hornung]

Hello all, I had my first tenant sign a 12-month lease agreement at my property in Alabama on July 1. She has already paid rent and the security deposit but is requesting to terminate the lease after 8 days because her mother passed away. She works for her mother's business and needs to move back home.

I have read that my tenant is responsible for paying the rent until a new tenant is found. 

What I should do with the security deposit? Are there any other charges or legalities I should know of?

Any other advice would be greatly appreciated!
