SALINA, Kan. (AP) — A 16-year-old Kansas girl has been ordered to spend nearly 16 years in prison in connection with the stabbing death of her younger sister.

Sierra Neihaus was sentenced Tuesday in Saline County. That’s where she pleaded no contest in March to amended charges of second-degree murder, felony theft, and two counts of interference with law enforcement.

Prosecutors allege Niehaus fatally stabbed her 13-year-old sister, Galazia, at the family’s rural home on Aug. 1, 2014.
