BURLINGTON, Iowa (AP) — An 18-year-old Burlington resident has pleaded not guilty to second-degree murder, accused of fatally stabbing another woman during a fight. Des Moines County District Court records say Kaylee Wilson entered the plea Monday. The court records say she intends to claim self-defense at her trial, which is scheduled to begin April 30.

She’s accused of stabbing 23-year-old Mallery Doak on Jan. 22 during a fight in front of Wilson’s Burlington home . A criminal complaint says the two had been arguing in instant messages over a man who’d fathered one of Doak’s children. Wilson reported that Doak threatened her for spending time with the man and said she was headed over to Wilson’s house.

Wilson told investigators that she then armed herself with a kitchen knife and hid it in her waistband awaiting Doak’s arrival.
