A woman stabbed at an Olathe park last week initially thought she was hit by a ball near the playground before looking down and realizing she was bleeding from her neck — and that chaos had ensued around her — according to court documents released Wednesday.
Witness accounts of the midday attack describe how a man charged with attempted murder acted strange and left people at Two Trails park feeling uneasy before he allegedly stabbed Jamie Trumpp, an Olathe mom who teaches middle school music.
A probable cause statement filed in the case details witness interviews conducted by Olathe police describing what appears to be a random attack at the park’s shelter, and the subsequent arrest of Kwan Noble Trezvant, 27, who is accused of stabbing Trumpp on March 19.
Officers responded around noon to Two Trails Park, 1000 N. Ridgeview Road, after reports of an armed disturbance, according to the police statement. Callers reported that a man wearing all black clothing, boots, a trench coat, a hat and a backpack had just stabbed a woman at the park and was seen running from the scene toward Ridgeview Road.
At the scene, officers found a group of people surrounding Trumpp, who was sitting on the ground on the east side of the picnic table pavilion. She appeared to be bleeding from the neck, but was alert, conscious and breathing, according to court documents.
Trumpp was taken to a hospital with a 5-inch wide, 1/2 inch deep cut to her neck, according to court documents. She got internal and external stitches to the wound and stayed at the hospital overnight for treatment and observation.
In an interview with police, Trumpp told officers she remembered sitting at a picnic table and felt “a very hard blow to the side of her head,” according to court documents.
“She thought she had been hit by a ball,” an officer said in the probable cause statement. “Jamie said the blow knocked her off of the bench and onto the ground. She said people ran to her screaming and she looked down and saw blood pouring out of her neck creating a pool of blood on the ground.”
Witnesses describe attack
One witness told police he was at the park with his children near the pavilion when he saw a man, later identified by officers as Trezvant, approach the pavilion acting “weird.”
Based on Trezvant’s behavior, the witness said he suggested to others in the area, including a woman with her child, that they should leave, according to court documents.
The witness then saw Trezvant walk back to the pavilion and picnic tables, approach Trumpp, yell a profanity and stab her, according to court documents. The witness told officers he saw Trumpp drop and start bleeding. The witness said he then ran toward Trezvant, who fled west across Ridgeview.
Police interviewed multiple other witnesses, each noting that Trezvant appeared to be acting strange, agitated or aggressive prior to the attack, according to court documents.
A woman at the scene told officers she was playing tennis with her daughter at the park when she heard someone yelling, “get away from there,” and “call 911.”
She told officers that she saw a woman on the ground surrounded by people and a man dressed in all black running south of the shelter. She chased the man at a distance and saw him set down some clothing, according to court documents.
The man then allegedly noticed her and picked the clothing back up and continued running, according to court documents. By that time, police had arrived, so she flagged down officers and provided directions on where he ran.
A grandmother who spoke to The Star under the condition of anonymity said she was also at the park with her grandchildren at the time of the stabbing. She described the attack as a seemingly random act of violence that caused chaos at the park.
The grandmother said that before the stabbing, she saw a man dressed in dark clothing acting strange and that he tried to grab a child. When Trumpp intervened, that’s when she was stabbed, the grandmother said. However, the police probable cause statement makes no mention of a struggle over a child leading to the stabbing.
Trezvant’s interview with police
Officers found Trezvant sitting in a lawn chair in the backyard of a home near the area, and he was taken into custody.
While being arrested, Trezvant allegedly said to officers, “I’m sorry she kept talking to me,” “She was calling me names. I asked her over and over again to leave me alone,” “I know I’m stupid. I didn’t mean to bro, she kept fu----- with me bro.” “She kept fu----- with me, I had no choice.”
Officers searched the backyard and found a knife on the ground. It appeared to be folded in, which concealed the blade, according to court documents. Based on the handle, the blade appeared to be 5 inches long, police said.
Trezvant was transported to the Olathe Police Department for an interview. While in the interview room, he appeared to be yelling or having a conversation with people who were not present, according to court records.
“He continued to make utterances about the incident and claiming that ‘you made me stab her,’ it’s the ‘police department’s fault’ that ‘I stabbed her,’” an officer said in the probable cause statement.
During his interview with police, Trezvant allegedly admitted to stabbing Trumpp in the neck because Trumpp would not stop “fu----- with him,” according to court documents.
A public defender representing Trezvant requested court proceedings to pause this week in order to determine if he is fit for trial.
In the motion, Trezvant’s lawyer 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. He is due to appear 10 a.m. Thursday for a preliminary hearing in Division 9 of Johnson County District Court.
