One of the two Wisconsin girls accused of trying to kill a classmate to appease a fictional horror character called Slender Man is appealing a judge's decision that keeps her in a secure facility.

A petition filed with the Court of Appeals says the decision against allowing the 13-year-old girl to live with her grandparents under strict monitoring amounts to excessive bail because she's no longer dangerous. The Journal Sentinel reports that the petition says the $500,000 bail is way beyond what's needed to secure her appearance in court.

A Waukesha County judge last month refused to reduce the bond for the girl and the 14-year-old charged with nearly killing a classmate by stabbing her 19 times.

The appeals court did not indicate Tuesday if it will consider the petition.
