Arielle Konig: She Went on a Birthday Hike. She Says Her Husband Tried to Kill Her.

On the morning of her birthday, Arielle Konig received a loving card from her husband. Hours later, she says he tried to throw her off a cliff and beat her in the head with a rock. A Hawaii jury has now found him guilty of attempted manslaughter.

The Birthday Trip

On March 24, 2025, Arielle Konig, a Maui-based nuclear engineer, traveled to Oahu with her husband, Dr. Gerhardt Konig, a Maui anesthesiologist, to celebrate her birthday. The couple had two young children, and Arielle later testified that she believed the trip was supposed to help repair their marriage.

That morning, Gerhardt gave her a necklace and a birthday card. In court, Arielle read part of the card aloud. He called her “Angel Face,” described her as the heart of their family, praised her as a mother, and wrote that he and the children had “hit the jackpot” with her. Arielle became emotional while reading it.

What Led Up to the Hike

At trial, jurors heard that the marriage had been under strain. Prosecutors said Gerhardt was upset over Arielle’s emotional involvement with a coworker, while the defense argued the confrontation on the trail was not planned in advance. The case drew intense attention because of what prosecutors say happened next: a doctor accused of trying to kill his wife on a cliffside trail during her birthday trip.

Later that day, the couple went to Pali Puka Trail near the Nuuanu Pali Lookout on Oahu. Arielle testified that she was already uneasy because the trail was narrow, steep, and close to the edge.

The Attack Arielle Described in Court

Arielle testified that Gerhardt told her to take a selfie near the cliff. She said that when she got close to the edge, he grabbed her by the arms and pushed her toward the drop. She threw herself to the ground and held onto roots and shrubs to keep from going over.

She told jurors that he then got on top of her and pulled out a syringe, telling her to hold still. She said she knocked it away. Prosecutors alleged that after that, he struck her repeatedly in the head with a rock. Arielle testified that he hit her multiple times and that she believed he was trying to knock her unconscious so he could push or drag her over the edge.

She screamed for help. At trial, jurors heard that she begged for her life and tried to get him to stop by talking about their children.

Covered in Blood

The attack left Arielle badly injured. Jurors were shown photographs and police bodycam footage that showed her with blood covering her face and head as she was helped away from the trail. Prosecutors also introduced evidence tied to a bloody rock they said was used in the assault.

Those images became some of the strongest evidence in the case. Trial coverage described Arielle as blood-soaked and injured in the moments after the attack.

The Two Hikers Who Heard Her Screams

Arielle survived because other people heard her.

Two hikers, Amanda Morris and Sarah Buchsbaum, both nurses, came upon the scene after hearing Arielle scream. A 911 call played for the jury captured one of them saying, “There’s a man trying to kill her. She has blood all over her face.” The caller also said they had heard Arielle screaming for help. Their arrival interrupted the attack.

After the Trail

Prosecutors said Gerhardt fled after the two nurses intervened. Police launched a manhunt, and he was captured about six hours later. One report said he was arrested near Nuuanu Pali Drive after a short foot chase.

The case later took another damaging turn when Gerhardt’s son and Arielle’s stepson, Emile Konig, testified for the prosecution. Emile told the jury that after the attack, his father called him on FaceTime and said he had tried to kill Arielle. He also testified that Gerhardt sounded suicidal and asked him to take care of the younger children. Emile said his father did not claim self-defense during that call.

The Verdict: Arielle Konig Case

In April 2026, after deliberations, the jury found Gerhardt Konig guilty of attempted manslaughter rather than attempted murder. According to the Associated Press, the jury concluded he acted under extreme mental or emotional disturbance, which reduced the offense. The conviction carries a potential sentence of up to 20 years in prison. Sentencing is set for August 13, 2026. His attorney said the defense plans to appeal.

Arielle was not present for the verdict. She has since filed for divorce.
