Yeah I thought about that too.... him just knocking her out quickly.... but then he was really lucky to get her to his car (since she was going to hers...unless she asked him to walk her to her car and he said just a minute let me do something in my car and she followed him..not wanting to be alone and that way he lures her to his car)...so if he managed to get her to his car, I still think, even a knock out... I mean still there would probably of been some blood, tissue or something...and if not, then still he would of had to pop his trunk and lift her up and get her in there, pick up all her stuff and then leave... seems even if it happened quickly, if he was able to just do that so quick, it still wouldnt be minutes... from the time they were walking to him driving out, minutes...didn't they say the time frame was reasonable for him to of walked to his car, gotten in and driven out? In my mind.... there is this thought...but I dont believe it...but, I had this thought of....what if she planned with him for her to just disappear.... she agreed to get into the trunk...for him to drive her home and help her disappear to Mexico..... DNA in the trunk was just maybe from crying.... saliva, tears...kinda the same .... I do not think she would ever do that to her mom... maybe in the moment she thought it sounded good...without really realizing all the pain and suffering it would cause because in that moment her pain was great and she just wanted to get away... maybe she mentioned she wanted to just disappear and he told her he could make that happen. Of course at this point it seems he would of already said thats what happened if it did.... but I think it sounds good to wish she is alive in Mexico.
