I have no idea if he decided to do it 3minutes before, a minute before or weeks before..
I believe he told Amber what his subconscience really wished for..He wished to "lose" Laci, the responsibilities of fatherhood, the hiding his doublelife, the danger and complications(both imagewise and financial) in discovery and divorce...and so the time came..
He had the means (his own strength, the boat to dispose of Laci's body), the motive(freedom), the opportunity from 8:30pm the 23rd,I don't know if he made one trip or two to the bay ..
I believe it happened while she was getting ready for bed on the 23rd. The color of her pants, worn to the salon, blouse (photgraphed on 24th) in dirty clothes basket she wore to the salon and she had on a bra. Blouse found in Feb. by Amy during a search with police, wadded up in a drawer.
Great post!
And as far as the legal concept of premeditation, it can occur in only a few seconds.
