If the crushing process specifically pressed on the off button, it probably would be an explicit disconection? How lucky (unlucky for us) would you have to be for this to happen?! Rather than put a phone in the crusher, still turned on, it would be simpler to just switch it off and then throw in? It really disturbs me how cold and callus the action of switching off the phone had to be... You have the mindset and thought process to perform this action, after harming another person or knowing another person had come to harm?!
Although, I do not feel it to be the case, Is there any possibility Claudia did this herself? It's been said that Claudia was very gullible, could it be possible that she had been convinced her life was in danger and she needed to leave it all behind and start afresh?
