Thought on Creepy Message: If someone was angry at her and they were close to her like family, meaning saw her daily, they could just drop hints about their anger around the house. If someone wanted to get rid of her for whatever reason, no matter how close they lived, why bother taunting her, just do it. This creepy message, (unless sent by someone to throw off LE and point the finger away from them), smacks of someone who WANTED MB and she did not want them. It hints at an intense, obsessive, fixated type of personality, who didn't have direct daily access alone with her enough to show her his/her rage, anger, sadness whatever, so they let the feelings fester and before killing her taunted her to let her know how they felt and possibly to scare her via the Internet. Maybe someone unknown to us that she met online, or maybe someone in her life that many know but had no clue that this person had feelings for MB. Maybe he/she tried something on in Austin and MB said no. I also believe that this person may have at one time fancied themselves a LEO at one point may have considered the profession and now it's just an alter-ego. Remember, we all choose Halloween costumes that we can relate to and that say something about us. I also think this person kept their feelings for MB hidden from others. This person spent time thinking about her enough to to write that creepy message, that really narrows it down.
