Girls weren’t killed in the car

CW’s truck forensics didn’t report any findings of the girls’ hair nor did they cite finding any bodily fluids. I find it highly improbable that CW killed the girls in the car because he stated he smothered them by pressing the blanket onto their face and pushing them back into the car seat. Bella fought. How can there be no trace of the girls’ hair when the back of their heads were pushed into the seat and there was struggle? Whilst CeCe was wearing a nappy/diaper, Bella was not. As horrible as it sounds, again, how likely is it that someone can be asphyxiated, especially a small child, and not in the very least lose control of their bladder? I think he is lying, yet again.
