Attorney: Slender Man Stabber's Confession Should Not Have Been Allowed in Trial

Nick Bohr, ABC12 WISN •

Her appeal challenges whether she really had the ability to waive her rights against incriminating herself.

"When she said she would give a statement waiving her rights, she didn't have any comprehension of what those rights were," Geyser's attorney, Matthew Pinx, said.

This week, the appeal gained some allies, with the Philadelphia-based Juvenile Law Center among those filing a supporting brief.

"We are deeply concerned that this was simply not a lawful or constitutional waiver of her rights," said Marsha Levick of the Juvenile Law Center.
