I am sure we will find out more about what position GR and CR were in when shot, they are the 2 who were moving targets,
if I was defense, I would want to know if any prints were Bobbie Jo , if she had blood on her shoes when police confiscated her shoes at station, tested to see if she left any prints, I doubt she was worried about where she trod when she went in saw the blood ran to their bedroom and then ran out, she must have been horrified, terrified and all the fieds in between, and she followed the path that the deceased were dragged so at some point she must have stepped in blood,
LE who went in to clear the house climbed on furniture, over the treadmill to get to the deceased as there was so much blood on floor, they didn't want to disturb crime scene
