3. How did that blood get in the underwear? She's been wiped clean, but there is blood on the crotch panel - so she had to have had them on, been injured, wiped clean, and then the underwear put back on with the longjohns with the urine stain in the front - otherwise, how could the blood have gotten there? Which means she had that pair of underwear on, she was injured, the underwear were pulled up, and then someone thought better of it, pulled them down, wiped her clean and then pulled the underwear back up. How else could the blood have gotten on that part of the underwear?
