BURLINGTON, Iowa (AP) — Authorities have arrested an 18-year-old suspected of stabbing to death a Burlington resident. Des Moines County court records say Kaylee Wilson is charged with second-degree murder. She’s being held pending $500,000 bail. She’s accused of stabbing 23-year-old Mallery Doak on Tuesday afternoon during a fight in front of Wilson’s Burlington home. The records don’t list the name of an attorney who could comment for her.

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.
