This is how I understand the much asked question about "Why did Jayme change schools?"
I have read the Wisconsin policy on open enrollment and it appears to have been a transportation issue. Although the sheriff said that Jayme transferred to Barron because Jayme's caretaker moved TO BARRON, I believe it is more accurate to say she had to transfer because her caretaker moved OUT OF the CAMERON DISTRICT (regardless of where she might have moved to.)
It seems likely that the aunt was Jayme's babysitter from the time she was born. So where would Jayme start school? Although you can send your child to a school outside your district, you must a) either drive them there yourself, or b) have a designated relative or caretaker living in that district where their bus can pickup and drop off your child. So it worked well for Jayme's parents to take her, or continue taking her, to the aunt's house in Cameron and have her start school there.
As Jayme got older, she didn't necessarily need a babysitter anymore, but as many have pointed out here, changing schools is a big deal, so she continued attending Cameron.
But, when the aunt moved out of the Cameron district, the only option for Jayme continuing school there was for either the Closs's or the aunt to drive her each day.
So apparently, the pros of moving Jayme outweighed the cons for the family. And although at times, Jayme may still have gone to the aunt's house after school/activities she didn't "need" a caretaker anymore, and was regularly picked up at the Closs home (per sheriff saying Jayme was alone at home for a time before her bus came) and dropped off (per neighbor.)
