I just read through the investigation report. Frankly, it is incredible that Meyer is not fired. Several times, the report explicitly doubts Meyer's (and his wife's) truthfulness when it comes to their statements regarding (1) what they knew about the 2009 incident, including Meyer's claim that she recanted the allegations--even Zach Smith himself denies this recant meeting and (2) how much the Meyers knew and the amount of information they shared with each other in 2015. Shelly Meyer claims she told Urban nothing about the texts, pictures, etc. and also states that she didn't believe Courtney Smith. The investigators seem doubtful...
Not surprisingly, almost all of the Meyers' statements/positions are unsupported by evidence and are completely self-serving.
