Perhaps this has been previously addressed, bare with me I'm new, and hopefully not breaking any posting rules: I have researched a little and read through many articles, I'm wondering if anyone has found anything suggesting that the bloody faced picture of the poi is a selfie taken with Beverly's missing cell phone, that perhaps he took it himself, and it automatically uploaded via iCloud to the victims iPad, which was noticed by a family member?
Therefore giving cause for the arrest warrant to be issued... It does appear to be a selfie... Just reading comments and this is a rumor, not sure if it has been discussed.
Given the poi obvious narcissistic personality disorder, immaturity, and manipulative skills ( all assumed from his various posts on FB) I wouldn't put it past him to take a bloodied selfie... Just saying!
