I am not exactly educated on the personality who steals undergarments, especially from a young teen, to wear. It is highly suggested of a distorted mind to want the used clothes of a young missing girl - it is odd, to say the least.
It is not what I think a typical transgender or gay cross-dresser would do. So to dismiss him so quickly must be based on an understanding that while this is odd, and why he just didn’t go buy pink tank tops at Wal-Mart, is likely due to the investigatory work done.
All the same, that lead has been shut down, and he is charged for stealing. That’s it.
