BURLINGTON, Iowa (AP) — An 18-year-old accused of fatally stabbing another woman in a fight has struck a plea deal during her trial in Burlington. The Hawk Eye reports that Kaylee Wilson pleaded guilty Friday to voluntary manslaughter and weapons charges. The deal was finalized after two days of testimony in her trial on a charge of second-degree murder. Lawyers on both sides agreed to recommend a total sentence of 15 years in prison.

Prosecutors say Wilson stabbed 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.
