What about voicemails that were deleted? Maybe that's why he kept checking them...or whoever did, to make sure that certain messages were deleted. Maybe that is how they were communicating...by voicemail. Voicemail is deleted once deleted and cannot be retrieved. Makes sense why the last call would be to voicemail.
Also, I LOVE that GW made sure to let Naegle know he WAS at church. Almost like he made sure he was. Couldn't make the meeting, but made a point to make the church meeting. Hmmm why not just stay away for the day???
I have to say I agree with you. Its seems there are a few of us that agree that GW was somehow involved. For what reason, I do not know. Probably LOTS of DELETED MESSAGES. Things that were private.
