Yep. Crazy mom was already blaming it on a classroom para and lunchroom assistant.
Here's a crazy mom(s) story.
Our middle school sits on the border of another district and the two closest middle schools in that district tend to be not-very-highly regarded so a lot of families want to open enroll at our school. It's become so full that our school has limited open enrollment.
One girl tried to open enroll there and mom brought in her ID but the address wasn't in our district so she was rejected.
The next day, a different lady that claimed to be the girl's mom came in with a piece of mail showing that she lived in the district and claimed that she was actually the girl's real mom. The "mail" evidence was rejected because it wasn't the correct type of mail (i.e. it needs to be something like an utility bill).
The third day, another different lady that claimed to be the girl's mom came in with a utility bill showing that she lived in the district and claimed that the other two ladies weren't the real mom but she was. This evidence was brought to the enrollment specialist and, even after having it pointed out that this was the 3rd lady that claimed to be the real mom, she accepted it. She said they would look into the "real mom" thing later because if they rejected her and this was actually the real mom the school could get sued.
There are two big short-term problems with this. First, as you might expect, this child was not the best behaved child in the world. Second, once a child is accepted at an open enrollment school it is really difficult to get them transferred back to their correct school if the parents don't want them at the school.
