the only reason they might be innocent of murder would be if they did rape her, and actually did push her out of the car, and the guards were there to pick her up.....
however, even that doesn't hold water because wouldn't they be all over the island looking for her night and day.....
case closed.......however, I have been wrong before...( there, I said...LOL)
LOL
Poor guards....I bet they'd love to get their hands on Urine and the Kal-pooies (Nancy Grace pronunciation)
My current theory is that she is buried at the hotel under renovation where the two guards were employed.
Bobcat on site? Concrete on site?
That would be the first place that I'd take the ground penetrating radar.
