WICHITA, Kan. (AP) — A California woman could go on trial next spring on charges of killing of her biological son’s adoptive parents in southeast Kansas.

The Wichita Eagle reports that 36-year-old Kisha Schaberg is charged with capital murder in the killings of Roger and Melissa Bluml. The couple was shot in November 2013 as they sat in a car outside of their rural Valley Center home.

During a hearing Friday, Sedgwick County District Judge Jeffrey Goering asked attorneys to tentatively reserve April 2016 for the proceedings. The trial could last a month or more.

Schaberg has pleaded not guilty and is jailed on $2 million bond. She could face the death penalty if convicted. Her biological son and two of his friends are scheduled for trial later this year in the case.
