Contacts

Question... So my husband went to prison back in 2007 and was released in 2012. Obviously that was before they were given tablets. We got together in 2012 3 months after he was released. During his time he was writing to two females. One was an ex girlfriend he had before he went in and another that he met while in there. Hasn't had anything to do with either one since he was released we've been married this whole time. He just touchdown at a unit about 3 weeks ago and got his tablet today. So today when he gets his tablet he calls me and says that those two females that he used to write to are listed as contacts on the tablet. He claims he has no idea how or why they are on there. Is this bullshit? I mean did TDCJ really go through all the trouble of keeping that info from snail mail and importing it onto the tablet? Please help me understand before I go left on this fool.
