Amber Russell, 19, of Lenexa, pleaded guilty Monday in juvenile court to first-degree murder, aggravated kidnapping and aggravated robbery for her participation in the Nov. 11, 2005, murder of Robin Bell at a Bonner Springs Dollar General. Bell lived in Tonganoxie, and managed the store.

Russell, who was 15 at the time of the murder, made a deal with the Wyandotte County District Attorney’s Office that she would be tried as a minor in exchange for her truthful testimony in the trials of Robert Haberlein and John Backus. Both men were convicted and have been sentenced to life in prison for their involvement in the murder.

Sentencing for Russell is scheduled for 9 a.m. May 13.
