OTTAWA, Kan. (AP) — A judge has ruled that statements from the suspect in a quadruple homicide in Kansas can be used at his trial.

Franklin County District Court Judge Eric Godderz ruled Friday that statements from 29-year-old Kyle Flack will be admitted during his trial in September 2015.

Flack is charged in the deaths of two men, one woman and the woman’s 18-month-old daughter in May 2013. The adults’ bodies were found outside Ottawa. The child’s body was found in nearby Osage County. Prosecutors are seeking the death penalty.

The Topeka Capital-Journal reports Flack made the statements during questioning by investigators.

The defense contended the questioning should have ended at least twice because Flack twice mentioned legal representation. . Godderz ruled that the statements appeared to be voluntary.
