That doesn't make any sense...

...I've never heard of anyone being forced to accept immunity. And forcing her to accept immunity doesn't force her to testify anyway, even if she can't plead to the 5th, she can still say "I do not recall."

This is just my speculation, but it sounds like she made a deal to testify against her compatriots in exchange for immunity, and has now backed out of that deal for some reason, and is remaining silent to avoid perjuring herself, having previously given a statement to the DA.
