The local police chief (or was it sheriff?) had already said he would open an investigation if asked to. Most opinions I read here on DU seemed to think the local DA would not take the case. However, if a legitimate FBI investigation, along with the huge amount of publicity related to it, were to take place would that possibly change the thinking of local authorities?
I think it is possible.

Would they then be able to subpoena the thousands of pages of documents that the Repubs refused to release?

I noticed they had Flaccavento t-shirts on. Before they said a word I told them not to worry about me. I am already planning on voting for him. Anthony Flaccavento (D) running against carpetbagger Trumpist Morgan Griffith (R) in VA 9th district.

They put a sign in my yard for me!
