A Maui doctor accused of trying to kill his wife during a scenic hike on Oahu has been found guilty of attempted manslaughter, bringing a dramatic end to a closely watched trial.
Jury Reaches Verdict After Hours of Deliberation
A jury in Honolulu County convicted Gerhardt Konig on April 8, 2026, after more than eight hours of deliberation. However, jurors declined to convict him on the more serious charge of attempted second-degree murder.
The conviction was based on extreme mental or emotional disturbance, a lesser charge that still carries significant prison time.
Konig now faces up to 20 years in prison, with sentencing scheduled for August 13. He remains in custody at a local correctional facility.
Conflicting Accounts of Birthday Hike Attack
The case centered on a violent incident involving Konig and his wife, Arielle Konig, during a March 24, 2025 hike on the Pali Puka Trail.
Prosecutors alleged that Konig:
- Tried to push his wife off a cliff
- Attempted to inject her with a syringe
- Struck her head with a rock
They argued the attack was fueled by jealousy over an emotional affair.
The assault reportedly ended when other hikers intervened and called emergency services.
Defense Claims Self-Defense
Konig’s legal team argued the case was a “he said, she said” situation, maintaining he acted in self-defense.
According to his testimony:
- His wife allegedly tried to push him off the trail
- A struggle followed, during which he struck her with a rock
- He denied attempting to use a syringe
Victim’s Testimony and Injuries
Arielle Konig told jurors the incident began when she hesitated to take a cliffside selfie. She said her husband became aggressive, grabbed her, and attacked her.
She described:
- Being threatened while alone on the trail
- Fighting off a syringe attack
- Sustaining a serious head wound, with rock fragments embedded
Medical testimony confirmed she suffered a deep skull laceration, though defense experts argued it was not life-threatening.
Jury Explains Decision
The jury foreperson said the panel did not believe there was enough evidence to prove intent to kill, leading to the lesser conviction.

- Sentencing set for August 13, 2026
