Not possible. We wouldn't know about the 11:57 call if it didn't show up on the phone records.
Yes, it's quite possible.
Megan Wright is why we know about the 11:57 (or 8:30 as she first said) phone call. And then the FBI told Picerno and Tacopina. Why wouldn't they tell the attorneys since MW had told the world?
The FBI would have the information but as Picerno said yesterday he can't get all the info.
Phone records have NOTHING to do with how we know about it. It was strictly Megan Wright. And she was told by the FBI. Now why she initially said 8:30 and then later said 11:57 is one of the biggest mysteries imo about this case.
