This is really sad.  
Per numerous district sources, Principal Lange has been displaying the same level of incompetence at Riverbend that she did at Page.  I assume that the teachers there will be accused of racism as well at the end of the school year, when all of this years complaints come out.
I also find it very interesting that Lange's sister-in-law filed an identical discrimination suit against her respective employer a couple years ago.  Same attorney, same chain of events (going on disability leave for stress), trying to cash in again via the race card.  Disappointing to say the least. 
Lange was probably a great teacher, but being an administrator takes a different skill set, and it unfortunately doesn't appear to be one Lange has.
Taking money from the district/students for a false claim of discrimination is truly despicable.  Shame on Mrs. Lange.
 I hope the settlement is worth the loss of respect and reputation it will cost you.
