Nothing quoted in the article discussed the deliberations but rather the significance of the evidence in general terms. If you read the section I quoted you will see that the press asking about deliberations would also violate the section you can't solicit such information from jurors.
You should also take note of the substance behind the quashing in that case.
1) the defendant didn't have time to wash or change before being picked up by police
2) the defendant only had a single particle of GSR on him
3) the prosecution argued that the single particle linked him to the murder
On appeal and retrial it was brought out that:
A) if he had committed the murders he would have had far more than just 1 particle of GSR on him because he had no time to change and all but 1 particle of GSR would not have transferred from his body and clothing in such a short period of time
B) that is is quite easy for a single particle to transfer
Not surprisingly the prosecution retrial flopped since they had zilch to link him to the crime. The same way there is zero physical evidence to link Sheila to the crimes. She had no reason to wash and change but more importantly no ability to change without the clothing she wore being found if she had changed. Naturally she had no ability to change out of the clothing she was killed in period. That clothing lacked GSR that would have been present had she shot herself sans moderator and her blood would have been found in the rifle had she shot herself sans moderator.
