Kyle Flack, accused in a 2013 quadruple homicide in Franklin County, listens to defense attorney Tim Frieden during a hearing on Friday, Aug. 29, 2014.

Ottawa ? A jail therapist testified Tuesday that an eastern Kansas man convicted of four 2013 killings once wrote that he wanted to die in a suitcase, but that he couldn’t remember penning that when she questioned him in jail.

Robin Burgess recounted her interviews of Kyle Flack while testifying during the penalty phase of Flack’s Franklin County trial, the Topeka Capital-Journal reported.

Flack, 30, last week was convicted of capital murder in the 2013 shooting deaths of Kaylie Bailey and her toddler daughter, Lana. Flack also was found guilty in the deaths of Bailey’s boyfriend, Andrew Stout, and his roommate, Steven White, at a rural Ottawa farmhouse.

It’s unclear what led to the shootings, which detectives believe happened on separate days in the spring of 2013. The toddler’s body was found in a suitcase in a creek.

Jurors will decide whether to recommend the death penalty or life in prison for Flack.

Burgess, who also was Flack’s therapist in a 2005 shooting case that resulted in Flack’s conviction of attempted murder, testified that she understood after Flack’s 2013 arrest that an older brother of his found some notes in which Kyle Flack wrote of wishing he would “dye in a suitcase.”

Burgess said she asked Flack about that and that he “did not remember anything about that.”

Burgess also testified that the brother had been mean or abusive to Flack, and she wondered whether the suitcase remark was linked to trauma perhaps inflicted upon Flack.
