I don't believe the jury was "shuffled" to get a guilty verdict, as you say.
The woman who was released did her own research as others have said. Big no-no. Juror number five, the doctor-lawyer foreman asked to be taken off and told the judge he couldn't render a verdict.
I agree with you here, but remember the Jury also did an "experiment" with the boat which is also "Usually" a no-no, but the Judge didnt call a mistrial. Another example of the guy wanting the case to get over with.
