THE PHONE (SW's)
Thanks again to everyone who responded to my earlier post about the phone. You gave me a lot to think about. I've formed an opinion I believe covers all the facts,
CW had SW's phone after he murdered her. He would want to know who called and he would want to search the phone, when he had time, to see who she had talked to (an atty maybe?), texts, etc. It would also tell him who was calling or texting SW that day, looking for her. NUA then shows up at the house forcing CW to race home where NUA and LE are waiting. Perhaps if CW hadn't been in a panic to get home, he would have dumped the phone on the way home. Or maybe he really wanted to search the phone before he dumped or destroyed it and figured all he had to do was deal with NUA. On his way home LE called for the code and he knows they're there. SW's phone wasn't just for personal, but also for business and it was always with her. Leaving it behind messes up his "she left with the girls and disappeared" story and maybe that's why he later hinted at a kidnapping scenario. So, he's at the house, with the phone, NUA and LE. At the first opportunity he hides the phone, by shoving it behind cushions or pillows on the sofa. Or maybe he just tossed it there. He knew he had to get rid of it and he probably knew someone was going to suggest calling or pinging the phone, since SW didn't or couldn't answer. It had to be done quickly, before more LE showed up (which they did) and he was more closely watched. I have to believe the first officers at the house were more interested in, and distracted by, looking for evidence of a crime, than watching CW.
Your comments made me think about how important SW's phone would have been to CW as a source of information (calls, texts, downloads, etc.) and as a forewarning (who's calling SW, how many times, etc.) which leads me to believe that one of the first things he did after the murder, was to acquire the phone. It was a little over three (3) hours from the time that SW entered the house until CW backed the truck into the garage. If he spent time searching the phone, that would explain why other things weren't done, like the dealing with the bedding, suitcase, etc. He could easily spend hours searching her phone, and not just for info about her, but to see what she may have communicated about him, and if she tried to track him on SM, etc. I have no doubt he's paranoid. It would explain how the time was used after the murder(s), if they took place early.
If this scenario is true, then his fingerprints would be all over her phone obscuring and covering other prints. I would think this could be evidence. I would also think that LE could tell if anything was removed/erased (by him) from her phone and might be restored.
