I find it a little confusing following so many different reporters who can only give 140 characters worth of info at a time, I am finding that most focus on exactly the same things and so must be not really listening to what is happening while they are typing, and I sometimes think I may have missed something.
Here, for example, I am also sure that I read both that the witness said that the phone came on and started pinging, and also that she also said it was plugged in and started pinging when turned on according to different reporters. I think I even remember reading that he was questioned by the defence in whether or not it needed to be charged and I believe that she said that she couldn't remember. Then I also recall reading that she didn't initially know how to turn it on as she does not have a Samsung phone, so I think if she did charge it, she must have had a charger in common.
I want to think that if she cleaned off the phone that she would have noticed any blood among the dirt and bird poop, or that the cop who visited her dug the thing she used to clean it with out of the trash to check for DNA. I also like to think that the phone was thoroughly searched by forensics in every crack and crevice that would not be removed by an ordinary cleaning. Maybe that will be introduced later? Or maybe the phone managed to stay clean, which I would find hard to believe whether it was kept in a shirt pocket or jeans pocket. Do we know which pocket he tended to keep his phone in?
