I am brand new here, but I have been itching to get my opinion posted. I though 20 phone calls showed guilt, but 90? I think he told Misty to turn off the phone to keep anyone from dropping by and realizing Haleigh was already gone. After leaving for work, he thought of all the reasons he needed to talk to Misty and enlisted her brother to go to his house to check on her. Misty, as instructed by Ronald, did not answer the door. If you aren't able to reach the babysitter, and your truly are worried, wouldn't you call your mom, your grandmother, or 911? Especially after calling the next door neighbor, (Misty's brother) and getting a report there was no one at home? I think you would, unless you knew what was going on.
Another thing that bothers me is the fact that LE believes he was at work the entire night. I worked for an Airline, and although we didn't punch time cards, we signed into our keypads. At Christmas when the traffic was at a standstill, we would call ahead to get a co-worker to sign in for us (to keep from being late for the start of our shift.) Why couldn't you use this tactic to leave your shift early, or to take a long lunch break? Maybe this is such an everyday occurrence at his job, no one deemed this suspicious. Maybe they have had second thoughts but are afraid of losing their job because of it. Where I worked, if you admitted to doing this, you would be fired on the spot. Where is a good place to post my theory as to what took place that night? I have some other observations I haven't seen posted that I would like to discuss
One problem with this theory is that Haleigh was seen by several neighbors after Ron went to work. She was out playing with other kids in the neighborhood.
