You seem to have forgotten something:
Innocent people do not claim they are waiting for the supposedly 'missing' person to come home by SELLING THE "MISSING" PERSON'S CAR THE FIRST CHANCE THEY GET, changing their hair color and growing a goatee, grabbing a bunch of cash and RUNNING to Mexico.
How about innocent people don't tell people that their wife is missing/dead two weeks before they actually disappear.
Innocent people who are waiting for their loved one to return don't try to sell their home FURNISHED within 30 days.
Oh - and don't forget that Scott had also contacted a realtor about selling the house. Couldn't do it thought; the house was joint property, and since Laci was still missing and hand't been declared dead, he couldn't sell the house.
