yes, like in the previously available court documents (like the Maryland indictment which was basis for the prosecutors to mention the charges) pretty much everything about the murders comes from those agents (actually mainly from the one of them). The transcript doesn't contain anything to add to the previously available documents, it just basically summarizes and mentions what has been already stated elsewhere.

No, this is not the case, and is in fact something you can only say if you haven't read the transcript of the sentencing hearing.
