A Saline County teen accused of stabbing her sister to death last summer was back in court Wednesday afternoon. The Saline County Attorney’s Office wants to prosecute Sierra Niehuas, who is now 15-years-old, as an adult. She is accused of stabbing her 13-year-old sister Galazia to death back in August.

Judge Patrick Thompson heard three people testify, including a Kansas Bureau of Investigation crime scene investigator, a staff member from the juvenile detention center in Junction City where Sierra is being held, and a psychologist who spent time with Sierra and her family.

The judge saw photos of blood evidence from the crime scene.

Testimony indicated that Sierra has been very respectful while incarcerated.

The psychologist indicated that Sierra has no memory of the stabbing. He said that it appears she had been a good student at school, and did not have any issues until she started spending time with some new friends, saying that there were two girls in particular.

Judge Thompson indicated that he would need  time to reach a decision once he heard closing statements, which were scheduled for next week.

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 will continue to be held in the Regional Juvenile Detention Center in Junction City.
