(AP) — State prosecutors are seeking mental health and prison records of an Ottawa man charged with killing four people on an eastern Kansas farm in May.

The subpoenas were mentioned at a brief hearing Thursday in Franklin County District Court for 28-year-old Kyle T. Flack, who is charged in the deaths of Andrew Adam Stout, Steven Eugene White, Kaylie Kathleen Bailey and Bailey’s 18-month-old daughter, Lana-Leigh in rural Franklin County.

Flack is charged with capital murder, first-degree murder, rape and criminal possession of a firearm.

Prosecutors filed subpoenas under seal for undisclosed business records. The defense attorney Ron Evans said prosecutors were seeking mental health and prison records. A spokesman for the state’s attorney general’s office said the state wouldn’t comments about motions filed under seal.
