I think she was likely dragged on some of the swimsuits, since they had both smeared blood and sand on them. That would most likely either point to Amdi or to someone trying to frame him, right? He would have only been able to move her by dragging her, and if he did it by using the swimsuits as... sort of a sleigh or wagon, I guess, there wouldn't have been bite marks on Lena or her clothes like there would have been otherwise.
