Lawyers for a man accused of killing four people in eastern Kansas have filed motions focused on the death penalty.

Kyle Trevor Flack is charged with capital murder in the 2013 slayings of Kaylie Smith Bailey and her daughter. He’s also charged with premeditated first-degree murder in the deaths of Andrew A. Stout, and Steven White. If convicted, Flack could face the death penalty.

The Topeka Capital Journal reports that Flack’s attorneys filed a motion asking the judge to explain to prospective jurors that they can sentence Flack to life in prison, rather than impose the death penalty. They also asked to question potential jurors about their views on the costs of execution versus lifetime imprisonment.

Flack is set to appear at a motion hearing in district court Tuesday.
