1 FACTUAL AND PROCEDURAL BACKGROUND

On October 10, 2019, N.A. was home alone with her dog. At about 11 p.m., N.A. was in bed when her dog started barking at the bedroom door. She got up, turned on the bedside lamp, opened the bedroom door, and started walking toward the living room when suddenly a screaming man came running toward her from the spare bedroom.

The man, later identified as Koch, grabbed N.A. and shook her, pushing her back into her bedroom and toward her closet. As Koch was trying to force N.A. into the closet he punched her in the face, breaking her nose. N.A. tried to lunge for her phone, which was on the bedside table across the room, but Koch had ahold of her and managed to get to the phone and toss it away before she could reach it. At that point, Koch started trying to wrap an electrical cord around N.A.'s neck to strangle her, but she managed to get her arm between the cord and her neck. As Koch continued to try to strangle her, N.A. believed he intended to kill her. When Koch could not tighten the cord because N.A.'s hand was in the way, he grabbed a glass jug and repeatedly hit her with it.

At some point during the struggle, N.A. realized she might be in a fight for her life and bit Koch's forearm and wrestled the jug away from him. After spitting out a chunk of Koch's hairy arm, N.A. started fighting back, using the jug as a weapon. The pair continued to exchange blows until N.A. smashed the jug on Koch's head. Koch then stopped his attack, got up, and tried to get out of the bedroom. Koch turned around to look at N.A., and she pleaded with him, "'It's okay. I'm just gonna open the door for you.'" She opened the door and Koch fled from the bedroom and out the front door.

After she watched Koch leave, N.A. locked the front door behind him, found her cellphone, and called 911. She stayed on the line with the dispatcher until Officer Jake Shailer of the Riley County Police Department arrived. Around this time, N.A.'s boyfriend called her after noticing her talking to Shailer on a security camera they had set 2 up for their dog. Shailer called for an ambulance and asked N.A. to tell him what had happened. Shailer also spoke with N.A.'s boyfriend on her phone. Paramedics soon arrived and took N.A. to a hospital in Manhattan.

At the emergency room, N.A. explained to the doctor and nurses the details of the attack, explaining that she had been repeatedly hit in the face with fists and a glass jug, been bitten, and strangled with an electrical cord. N.A. told the doctor that she was lucky she never lost consciousness and thought the intruder was going to kill her. Shailer interviewed N.A. again after she was admitted to the hospital—their conversation was recorded on Shailer's Axon. N.A. explained the entire ordeal, including about Koch trying to wrap the electrical cord around her neck during the attack. Detective Janelle Compagnone conducted another, more detailed interview with N.A., during which N.A. indicated that she was certain that Koch was trying to kill her. Shailer left the hospital to join another officer who had followed a trail of blood leading from N.A.'s house to an apartment building a block down the street, later determined to be Koch's residence.

Shailer and other officers entered the building, a split level building with several apartments, and first spoke with Koch's downstairs neighbor, who told the officers that he had reported a break-in at his apartment earlier that evening. The officers followed the blood trail up the stairs to Koch's apartment, where they spoke to Cynthia Arganbright, Koch's ex-mother-in-law, who lived in the apartment with Koch. While Arganbright initially hesitated to let the officers inside, she relented when they mentioned the blood leading to the apartment. Although the officers found additional blood around the apartment, they did not find Koch. The officers later obtained a search warrant for the apartment and discovered items stolen from the downstairs neighbor.

Koch initially fled to the house of his drug dealer, then skipped town to his brother's house near St. Louis. Koch called his brother asking for help, but his brother

3 contacted the police and alerted them to Koch's plan. A warrant was issued for Koch's arrest and he was picked up four days later in Missouri.

On October 11, 2019, the State initially charged Koch with aggravated kidnapping, aggravated burglary, aggravated battery, residential burglary, and two counts of theft. But on November 19, 2019, the State filed an amended complaint adding a charge of attempted murder in the second degree.

The case proceeded to trial in August 2022. Following the State's presentation of its case-in-chief, Koch testified on his own behalf. He began by conceding that he had committed the charged crimes of simple residential burglary and theft relating to his neighbor's downstairs apartment. Koch explained that his motivation to commit these crimes was to support his drug habit. Koch testified that he was addicted to methamphetamine and had been using it repeatedly on the day he broke into N.A.'s residence.

Koch recalled that on the night of October 10, 2019, after either shooting or smoking methamphetamine, he left his house to buy cigarettes, when he noticed N.A.'s house was completely dark and had a keyless lock on the door. Koch knew such locks frequently malfunction and are often left unlocked. Koch discovered the door was unlocked, so he entered to look for items to steal. While moving through the house, Koch ran into N.A. and "really freaked out." Koch recalled that he began pushing N.A. and punching her: "[W]e were both moving and pushing and reacting to each other so, I mean, I'm not gonna say she was attacking me, but she was definitely defending herself." While Koch admitted to repeatedly hitting N.A. and biting her, he testified that at no point was he trying to push or confine her to any location and never gained control over her. He claimed that he never tried to strangle N.A., speculating that the electrical cord was simply tangled around them during the struggle. Koch denied having any intent to

4 kill or kidnap anyone and stated that he had believed N.A.'s home was empty when he entered. Koch thought the entire ordeal happened very fast and lasted about one minute. After N.A. bashed him with the glass jug, Koch decided it was time to flee the scene. He confirmed that N.A. had to help him open the door. At that point, he ran back to his house, where he later escaped via a window to the roof when the police arrived.
