Kansas man charged with attempted murder after unprovoked park stabbing

Olathe Man Charged with Attempted Murder in Unprovoked Park Stabbing of Local Teacher

A 27-year-old man, Kwan Noble Trezvant, is in custody and facing charges of attempted first-degree murder following a stabbing at Two Trails Park in Olathe, Kansas, on Thursday, March 20, 2026. The victim, 38-year-old Jamie Trumpp, a choir teacher at Indian Trail Middle School, was reportedly attacked while at the park around noon and is expected to survive her injuries. The attack, according to police, was “completely unprovoked.”

The Johnson County District Attorney’s Office alleges that Trezvant intentionally cut Trumpp with a knife, constituting an attempt to unlawfully and with premeditation kill another person. This definition, as outlined in court documents, requires proof of intent to kill, even if the attempt failed or was interrupted. Trezvant is currently being held on a $500,000 bond and is scheduled to appear in court again on March 26.

A Random Act of Violence Shakes the Olathe Community

The incident has deeply affected the Olathe community, particularly those connected to Indian Trail Middle School and Olathe West High School, where Trumpp’s husband, Matt Trumpp, coaches soccer. Following the attack, community members quickly organized a meal train to support the Trumpp family during Jamie’s recovery. This outpouring of support highlights the close-knit nature of the area and the shock felt by residents.

Prior Legal Issues for the Suspect

Court records reveal that Trezvant has a prior criminal history in Johnson County. In August 2024, he pleaded guilty to misdemeanor battery of a law enforcement officer, resulting in a nearly four-month jail sentence. In November 2020, he pleaded guilty to obstructing the legal process and possession of drug paraphernalia, receiving a sentence of time served. These previous convictions raise questions about potential contributing factors to the alleged attack and the existing support systems available to Trezvant.

Understanding Attempted First-Degree Murder in Kansas

The charge of attempted first-degree murder carries significant weight under Kansas law. The legal definition, as stated in court documents, requires prosecutors to demonstrate that Trezvant acted “unlawfully, feloniously, intentionally and with premeditation” to kill Jamie Trumpp. Successfully proving premeditation – that the act was planned and not simply impulsive – will be a key element of the prosecution’s case.

What Happens Next in the Legal Process

Following his initial court appearance on Friday, Trezvant awaits his preliminary hearing on March 26. This hearing will determine if there is enough evidence to proceed to trial. If the judge finds probable cause, the case will move forward, potentially involving further investigation, evidence gathering, and a jury trial. The process can be lengthy, and Trezvant is presumed innocent until proven guilty beyond a reasonable doubt.
