The iPhone does not have any special value, but a great deal of sentimental value. It belongs to Brooke's mother, Mackenzie Robinson, and holds many photos of Brooke, including the last ones that were taken.
A family friend contacted me earlier this evening and asked if I could post something. It is not believed that the phone was stolen, but that it was misplaced during all of the confusion last week.
Anyone with any information about the phone can send me an e-mail at firstname.lastname@example.org and I will pass it along to the family friend.
