Lawyer requests mental evaluation for man accused of stabbing Olathe woman
An attorney representing a man charged with attempted first-degree murder in Johnson County requested court proceedings to pause in order to determine if the man is fit to stand trial.
Kwan Noble Trezvant, 27, is charged with attempted first-degree murder for his alleged involvement in the stabbing of a woman at Two Trails Park in Olathe last week.
In a motion filed in Johnson County District Court Monday, Trezvant’s public defense attorney said he has, “a good faith belief that there is reason to believe that Mr. Trezvant is suffering from a mental illness or defect which may render him incompetent to stand trial.”
Trezvant appeared in court for the first time in the case Friday afternoon and his bond was set at $500,000, according to court records. He is due back in court 10 a.m. Thursday for a preliminary hearing.
Stabbing shocks Olathe community
Officers responded around noon March 19 to the 1000 block of North Ridgeview Road after reports of an armed disurbance. Upon arrival, they found a 38-year-old woman suffering from what appeared to be a stab wound, according to Sgt. John Moncayo, a police spokesman.
A police report identified the woman stabbed as Jamie Trumpp, a mom of three children who teaches middle school music in the Olathe Schools district.
Trumpp was taken to Overland Park Regional Medical Center for treatment. Police said in an update Friday that Trumpp is expected to survive her injuries.
Since the stabbing, the Olathe community has flocked to show its support for Trumpp and her family. A Meal Train fundraiser has gathered funds for medical expenses and people volunteered to cook or purchase meals during Jamie Trumpp’s recovery.
A local grandmother who witnessed the attack described the incident as a seemingly “random act of violence,” that caused chaos at the park last week as parents scrambled for safety.
Olathe residents who live near the park said they are surprised a violent act could happen so close to home — at a park they frequent and find safe.
Trezvant’s criminal history
Kansas online court records show Trezvant has been a defendant in seven criminal cases, two of which were juvenile misdemeanor cases.
A felony drug possession charge against Trezvant was dropped by prosecutors in August 2024 when he pleaded guilty to misdemeanor battery on both law enforcement and health care workers, court records show. At the time, he was sentenced to 119 days in jail.
Trezvant was also charged with felony criminal threat in Douglas County and sentenced to a year of supervised probation from June 25, 2024 to June 25, 2025. His probation was revoked in October 2025, court records show.
In previous cases, Trezvant also faced charges for misdemeanor drug possession, criminal damage less than $1000, obstruction and criminal trespassing.
As a juvenile, Trezvant was charged with harassment by phone in 2015 and disorderly conduct in 2016, court records show.
