SALINA, Kan. (AP) — A judge has ruled that a 15-year-old girl will be tried as an adult in the fatal stabbing of her 13-year-old sister.

Saline County District Judge Patrick Thompson ruled Tuesday that Sierra Niehaus will be tried as an adult in the Aug. 1 death of Galazia Niehaus in northwest Saline County.

Thompson ordered that juvenile charges be dropped when an adult charge of first-degree murder is filed. Formal reading of charges is set for April 27.

The Salina Journal reports attorneys who had represented Niehaus in juvenile proceedings were dismissed and a new attorney will be appointed.

Thompson said Niehaus has shown no remorse or any other reaction to the death of her sister.

Niehaus will be transferred from juvenile detention in Junction City to the Saline County Jail.
