Do you find it odd that he calls her work and asks.. 'How's Lori?'.. instead of 'Is Lori there?', or 'Is Lori busy?' or 'Can I speak to Lori?'.
Well, given that both he and he co-workers would have known that she had left work very upset on Friday afternoon after receiving a disturbing phone call, not as odd as it might be. A husband who saw his wife leave for work still upset about something which had caused her to leave work early the previous work day, might well ask her co-worker how she's doing. But still odd, given what we know.
I do. If he killed her Sunday night, why did he call her work that morning and pull the disappeared jogger routine so soon? Why didn't this jerk go about his business Monday and act as if he didn't know she was missing until Monday night when she was supposed to get home from work? He would have had a lot more time to get his story straight.
VERY ODD, since his next statement is that he is looking at her work clothes still at home!!! He isn't as clever as old Scotty boy~!
