Prosecutors say Amber Russell was sentenced Wednesday in Wyandotte County juvenile court.
Russell was 15 at the time of the killing. She pleaded guilty last month to charges of first-degree murder, aggravated kidnapping and aggravated robbery.
Prosecutors agreed not to charge her as an adult in exchange for the plea and her testimony against co-defendants John Backus and Robert Haberlein. The two were sentenced in March to life in prison with no chance of parole for 50 years.
