Snipped from the story linked above:
"In one phone call, Teresa Banfield told Peres Magalhaes she’d been texting with one of the defense attorneys, who offered to make a delivery during a jail visit, according to the search warrant. The document states Teresa Banfield then read the text aloud to Juliana. “Hi Tess. I will be going to visit Juliana this morning. Expected to be there around 9. If I, you know, if I have anything I’d give it to her," the affidavit said."
If I understand the news story correctly, the prosecution just has a RECORDING of the jailhouse phone call where TB reads JPM a text *allegedly sent* by one of the defense attorneys. For all we know, TB was just making up the contents of the text to convince JPM that the Banfields were fully on her side and doing all they could to get her off the hook for the murders.
IMO only: The way that TB is reported to have read this "text" to JPM sounds to me like she could have been just fabricating it as she went--"If I, you know, if I have anything I'd give it to her." Also, if TB and this attorney were friendly enough that the attorney referred to TB by her nickname (Tess, rather than her given name of Teresa) AND they were communicating via text rather than via the more "official" route of email, it seems a bit odd to me that the attorney would start a text message with "Hi Tess."
