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.

Jurors convicted an eastern Kansas man on Wednesday in the fatal 2013 shootings of three adults and an 18-month-old girl whose body was found in a suitcase in a rural creek.

Kyle Flack, 30, was found guilty of capital murder in the deaths of Kaylie Bailey and her toddler daughter, Lana, meaning he could face the death penalty when sentenced next week, according to Franklin County District Court Administrator John Steelman.

Flack also was convicted in the deaths of Bailey’s boyfriend, Andrew Stout, and his roommate, Steven White, who lived in a rural farmhouse where Flack sometimes stayed in Ottawa, about 50 miles southwest of Kansas City.

It’s unclear what led to the shootings, which detectives believe happened on separate days in the spring of 2013. Investigators said Flack told detectives that two drug dealers may have been involved, but detectives determined those people didn’t exist. Authorities also say he indicated Stout killed White during a dispute over rent, but that the interview ended after Flack asked for an attorney.

The defense called no witnesses during the trial. Jurors began deliberating Wednesday morning.

Prosecutors said investigators believe White was killed first, around April 20, 2013. The 31-year-old’s body was later found under a tarp in an outbuilding near the farmhouse. Authorities believe Stout, 30, was shot on April 29; his body was found in his bedroom under a pile of clothes, the Kansas City Star reported.

Investigators said Bailey’s body also was found in a bedroom, partially clothed with her hands bound behind her back. Investigators believe the 21-year-old mother and her daughter were killed on May 1, 2013.

The adults’ bodies were found about a week later at the farm. Search crews found the child’s body in a suitcase floating in the Tequa Creek about a week later, the newspaper reported.

Prosecutors presented two weeks of testimony from dozens of witnesses and hundreds of exhibits during the trial.
