OTTAWA, Kan. (AP) — Lawyers for a Kansas man accused of killing four people will get more time to respond to prosecutors’ attempts to use comments the defendant made to police.

Kyle Flack is accused of killing Kaylie Bailey, her 18-month-old daughter, Lana-Leigh; Andrew Adam Stout and Steven Eugene White last spring in Franklin County. He’s charged with first-degree murder in the deaths of Stout and White. Prosecutors are seeking the death penalty against Flack for the deaths of Kaylie Bailey and her daughter.

The Lawrence Journal-World reports a detective testified that Flack told him he killed White. Flack’s lawyers contend the statement shouldn’t be used during trial because he made it after asking if he needed a lawyer.

A judge Friday set an Aug. 29 hearing to consider the issue.
