length of liability

What is the name of your state? Washington State

Tenant A gave proper notice but two days before move out tenant A's son broke the glass fireplace insert in the rental home. Tenant A brought insert to dealer, had new glass installed but gave the landlord the insert to install because the seals were not dry. landlord charged for installation and gave back deposit and release.

70 days later tenant B has moved into the home and a letter sent by Landlord to tenant A that the fireplace was still messed up and tenant A was liable for the repairs.

IS tenant A responsible after 70 days? What recourse would one take?

Tenant A should sit back and see if he/she is sued. If sued, tenant A should present evidence of deposit refund and release. How does tenant A know if whether or not tenant B now broke the glass? It appears the landlord is negligent in his/her own charged back installation of the insert?
