How to buy forclosed property from bank that no longer exists?

[Stanley Cenatus]

I am fairly new to the real estate game so pardon my poor description of this situation. My father lost his investment property in 2008 to the bank. He explained to me that the very same bank who foreclosed his property had collapsed and the bank no longer exist. So since 2008 this property has been sitting vacant. However my father still pays the taxes and still has the keys. My father is willing to sell me this property however I want to be sure that this deal doesn't come to bite me in the future. Has anyone heard of a situation similar to this? If so, how should I handle it?
