Wife Testifies Against Anesthesiologist Husband Who Allegedly Pushed Her Off Hawaii Cliff

Arielle Konig calmly recounted the hike while on the stand in the ongoing trial in Honolulu on Tuesday, which marked exactly one year since the incident and fell on her birthday. She testified that her husband was on top of her, "trying to get me closer to the cliff," and that he then produced a syringe, saying, "Hold still," before she batted it away.

Gerhardt Konig, a Maui anesthesiologist, is charged with second-degree attempted murder for the alleged assault on his wife, Arielle Konig, at the Pali Lookout on March 24, 2025. He will admit to striking his nuclear engineer wife on her head with a rock on the trail, but his lawyer told jurors during opening statements that he did not intend to kill her.

Gerhardt Konig is accused of beating his wife with a rock on the Pali Puka Trail on Oahu on March 24, 2025. He has pleaded not guilty to second-degree attempted murder. The two had traveled to Oahu from their home in Maui to celebrate her birthday.

According to Deputy Prosecuting Attorney Joel Garner, Gerhardt grabbed Arielle by the shoulders and pushed her backwards after she refused to stand at the cliff's edge for a selfie. She fell, and they began wrestling. Gerhardt got on top of her, straddling her, at which point she saw a syringe in his hand, hit it, and it fell away. Arielle testified he told her, "F you, you're done. I'm so, so sick of your s , so done with you," while holding her down, and that he produced a vial before telling her, "Shut the f up. Nobody's gonna hear you out here, nobody's coming to save you."

Two nurses, Sarah Buchsbaum and Amanda Morris, witnessed Arielle being attacked when they happened upon the scene while out hiking. They did not know the Konig couple. Buchsbaum's 911 call, played for the jury, captured her saying: "911? Hi. Someone's currently being attacked on the top of Pali Puka. 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."

Amanda Morris testified she and a friend were just minutes into their hike when they heard screams, thinking someone had fallen, only to see a man standing over a woman. When the prosecutor asked if she could see the man doing anything, Morris responded: "Yes, he was hitting her with a rock."

Prosecutors told the jury that after the attack, Gerhardt called his 19-year-old son, Emile, on FaceTime and told him: "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." Prosecutors called the conversation a confession.

Defense attorney Thomas Otake framed the case in starkly different terms during opening statements, telling jurors: "This human story can be summarized best in three words: Unfaithful, unwilling and untrue," and that he would share "the complex human interactions between Gerhardt and his wife" between December and March. Otake claimed Arielle started what he called an "unplanned, unanticipated scuffle" and hit her husband with the rock first, during an argument stemming from her affair.

Arielle was taken to an area hospital in critical but stable condition with multiple face lacerations. Following the attack, she secured a 180-day restraining order and filed for divorce, accusing him in the petition of sexual assault. She filed for divorce in May 2025, seeking full custody of the couple's two young children.

Gerhardt Konig has been in jail since his arrest. A judge denied his motion to dismiss the indictment last month. The Pali Puka Trail sits above the Nuuanu Pali Lookout, a short, steep, and exposed ridge hike on Oahu's east side. Hikers who know the trail describe portions where one is "literally on the edge of a straight drop-off cliff." The trial is expected to last until mid-April.
