OTTAWA, Kan. (AP) — Jurors have convicted an eastern Kansas man in the fatal shootings of three adults and a toddler in 2013.

Franklin County court officials say the jury found 30-year-old Kyle Flack guilty of capital murder on Wednesday for the deaths of Kaylie Bailey and her 18-month-old daughter, Lana. That means Flack could face the death penalty when sentenced next week.

He 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.

It’s unclear what led to the shootings. Investigators say Flack at one point told detectives that two drug dealers may have been involved, but detectives determined those people didn’t exist.

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