Hawaii Doctor Claims Self-Defence in Attempted Murder Trial Over Wife's Affair
A Hawaii doctor on trial for the attempted murder of his wife has claimed he acted out of self-defence after a violent confrontation erupted over her alleged affair with a co-worker. Gerhartdt Konig, a 47-year-old anesthesiologist, admits to striking his wife Arielle, 37, with a rock at an Oahu beauty spot in March 2025, but his attorney asserts she attacked him first during opening statements this week.
Emotional Courtroom Scenes and Conflicting Accounts
The renowned medical professional broke down in tears as his trial commenced, with jurors hearing a distressing call he made to his son immediately after the incident. In the recording, Konig confessed to attacking his wife and declared his intention to end his own life. The court was presented with a graphic image of Arielle following the alleged assault, showing blood seeping from her head and facial injuries sustained from the rock attack.
Defence attorney Thomas Otake argued that the injuries were less severe than they appeared, describing only a small laceration to her eyebrow. He contended the case should be tried as assault rather than attempted murder, telling jurors: 'She picks up a rock and hits him in the face with it, and he quickly reacts, human reaction, grabs the rock, hits her twice, and stops.'
Prosecution's Allegations of Premeditated Violence
Prosecutors presented a dramatically different narrative, alleging Konig attempted to push his wife off a ledge on the Nuʻuanu Pali Lookout hiking trail before trying to stab her with a syringe and repeatedly bashing her head with a jagged rock. Deputy prosecuting attorney Joel Garner described the attack, stating: 'He starts to take that rock and bash her in the head multiple times. "Help, help, help" is what Arielle says while the defendant is hitting her.'
Garner revealed Arielle is scheduled to testify next week on the one-year anniversary of the alleged attack, where she will admit to a three-month affair with co-worker Jeffrey Miller. According to prosecutors, she had previously confessed to the infidelity and believed the couple had moved forward, attending couples counselling and planning a romantic Oahu trip for her birthday.
Financial Disputes and Marital Breakdown
The defence presented evidence of escalating marital tensions, with Otake claiming Arielle withdrew $130,000 without her husband's knowledge, prompting Konig to file a temporary restraining order. This legal action reportedly led her to file for divorce before the couple attempted therapy. Prosecutors countered that Konig meticulously planned the Oahu trip, including researching the cliffside hike where the summit drops several hundred feet.
Eyewitness Testimony and Dramatic 911 Call
Eyewitness Sarah Buchsbaum testified that she and a friend observed the doctor on top of his wife during the struggle. Jurors heard her frantic 911 call from the scene: 'There’s a man trying to kill her. She has blood all over her face. We heard her screaming "help, help, help me, help me" and then we saw a man over her, and then she crawled out with blood on her face. He tried to kill her.'
Prosecutors alleged the attack only ceased when the two female hikers intervened, after which Arielle scrambled away and Konig fled into the forest. The subsequent eight-hour manhunt concluded when police officers spotted him emerging from the woodland and arrested him after a brief foot pursuit.
Disturbing Phone Call and Suicide Threat
During the emotional courtroom proceedings, audio was played of Konig's FaceTime call to his 19-year-old son Emile, where he confessed: 'I’m not going to make it back. I tried to kill Ari, but she got away. She’s been cheating on me for the last several months. I’m at the end of my rope. I’m going to jump. I gotta hang up, so the police don’t find me.'
The defence countered prosecution claims about the syringe, arguing police never found such evidence or proof of attempted injection. The couple, married since 2018, share a $1.5 million home in Maui. Konig has pleaded not guilty, with his trial expected to continue until mid-April as both sides present their conflicting versions of events on that fateful hiking trail.
