Wells informed Schoenfield, Jastremski, and McNally that he was going to have a 3rd party (Brad Maryman) execute search terms on their phones' text messages. There was nothing to stop them from deleting the texts prior to the search. Furthermore, AT&T's letter to Brady explicitly said the incoming and outgoing text messages from 9/1/14 through 3/15/15 could not be retrieved. So if any evidence did exist, it was either deleted before Maryman's search or lost forever since AT&T can't retrieve texts within 72 hours. Use common sense, if you're Schoenfield, Jastremski, and McNally you are going to delete any evidence off the phone within a minute of it being sent to protect your superstar. Nobody is dumb enough to leave that on their phone.
Not to mention that Brady claimed he always destroys his old cell phones yet still had his phone from 2014, prior to 9/1/14. His story simply didn't add up and they didn't have the evidence from the time of the incident since the phone with evidence from 9/1/14-3/15/15 was missing. 2nd Circuit judges wouldn't be admonishing Brady if the story added up. The evidence simply doesn't exist that Brady is innocent.
