Well. A jury of wise, middle age folk are going to have to decide if a man who:
Was having an obssessive affair with wife's best friend
Lied about it
Amended, but still lied about it ('tryst', once) Actually, I believe it was his PR rep who put out the idea of a one-time, alcohol-fueled tryst to Joe Mahoney. I don't know if this is what GR conveyed to her or if she just made it up
May well have known his wife had made an appointment with a divorce lawyer
Lied (via very unsubtle hints) about wife's drug use/betrayal etc (hinted to media; screamed about it to his in-laws several days after she went missing; tried to show them naked pictures of Jen and a bag of medications he said she was abusing)
Appeared to know she was missing and in danger far, far too early
But then contradicted that caring attitude by ....appearing not to care much at all
Did not search for her
But searched for her phone, and miraculously found it
Had money troubles and stood to gain from her death
Lied about working when she went missing, and the route he took to get to the Y.
Unless this jury turn out to be a Casey Anthony remix, they will surely convict.
