Yeah, I wonder if all the incriminating texts were deleted shortly after they had been exchanged, or if he deleted many shortly before he killed himself. I mean, I know that he obviously was deleting along the way, considering this was goign on for 7 years, but I just wonder if he was sitting there that morning cleaning up the last bit of evidence on his phone. Maybe he had fleeting thoughts about committing suicide, but not to the point of planning it all out until just the morning of. He knew that they were about to find out about everything he had been doing with the Explorers money, and he may have just made the decision to kill himself that morning. That would explain not removing the coke packets from his desk, since he didn't go in to the station that morning.
So he kills himself and then leaves his family holding the bag, so to speak. You can't tell me that with that many years in LE he didn't know they could retrieve deleted texts. I mean, honestly! You don't even have to be in LE to know that! Hopefully we will soon hear the extent of his family's knowledge of all of this.
