Not sure how I missed this, but on Dec. 25 (four days after Sticca was trying to contact Roig regarding her missing phone), we have this email from Apple security to Sticca. Notice that Apple says "...regarding an iPhone that is in your possession as evidence".

Does this mean that Sticca found one of the 2 missing iphones, which we are to assume, is either teacher [x]'s Verizon phone, or Roig's Sprint phone? Or, maybe some other person's phone?
