A Saline County teen accused of stabbing her sister to death last summer will be prosecuted as an adult. Sierra Niehaus, who was 14-years-old at the time, is accused of stabbing her 13-year-old sister to death back in August.

The Saline County Attorney’s Office had filed a motion to prosecute Sierra, who is now 15-years-old, as an adult.

After hearing several days of testimony over the past several weeks, and then closing arguments Tuesday morning, District Court Judge Patrick Thompson made a decision. Saline County Attorney Ellen Mitchell tells KSAL News that the judge determined that Sierra will be tried as an adult.

The case stems from the death of 13-year-old Galazia Niehaus. The Saline County Sheriff’s Office was notified of a stabbing at about 1:45 in the morning on Friday, August 1st. When deputies arrived at the scene in Northwest Saline County they found the body of Galazia, who had been stabbed to death.

Sierra was being held in the Regional Juvenile Detention Center in Junction City. Following Tuesday’s ruling, she was transferred to the Saline County Jail.

Mitchell says that Sierra is being held in the Salina jail on a million dollar bond. Her juvenile counsel has been relieved, and she will now get a public defender. She will next appear in court, as an adult, later this month.
