Yes, of course. Especially in that hot climate.
And I believe you are right about the way it went down. I dont believe they set out to kill her but she fought them I am sure. Then the little cowards killed her and panicked and called Daddy for help.They then spent the dark hours before dawn covering their tracks and disposing of Natalees' body. I believe they buried her INITIALLY at the grave that Tim Miller mentioned and then went back for her later and put her someplace that had already been searched, like the landfill. All four of them should hang.
