Speed, I beg to differ. What we are being asked to believe is that
1) Laci and Scott had an argument (about Amber)-
2) Scott left and went fishing by himself.
3) McKenzie the dog left and went for a walk by himself.
4) Laci (8 mos.pregnant) waited a few minutes and then walked 90 miles to the Bay, tied weights/anchors to her wrists and ankles and threw herself in the water.
This man proves the truth of Califormia Drug Rule #1: "Never Buy Drugs by Price Alone. Cheap Is Not Always Good!"
Now that you put it that way - I'm sold.
