And Christina Parcell knew that the only person who had possession of these photos of her was John Mello. And they were taken when they were dating back in 2010 or 2011, when she was much younger. And there was also included in there a photocopy of an escort site. And it was claiming that Christina Parcell had been posting on an escort site as a prostitute looking for business.

None of the photos were connected to the escort site. They basically took a screenshot of an escort site and then copied and pasted the URL onto some private pictures that Christina and John had shared years ago.

These packages all came from Greenville or Tennessee. And so we knew the person who sent them out or who put them in the mailbox and prepared them had to be living in the Greenville area. John Mello was in Italy.

They texted, and then he attempted to call her with no answer, which is the reason that he came to the house. And by looking at his phone, as well as Christina's phone, we were able to confirm that he was, in fact, telling the truth. Because normally when she leaves somewhere, she'll send me a text or something on my way back, and I didn't hear from her.
