Former UPMC Doctor Convicted of Attempted Manslaughter After Hawaii Hiking Attack
A Honolulu jury has reached a verdict in the trial of Gerhardt Konig, a 47-year-old former UPMC anesthesiologist, finding him guilty of attempted manslaughter. The conviction follows a three-week trial centered on a violent encounter between Konig and his wife, Arielle Konig, during a birthday trip to Oahu in March 2025.
The Verdict and Legal Implications
On Wednesday, April 8, 2026, the jury delivered a unanimous verdict convicting Gerhardt Konig of attempted manslaughter based upon extreme mental or emotional disturbance. The jury declined to convict him on the more severe charge of second-degree attempted murder, stating that the evidence did not sufficiently prove he intended to murder his wife. According to NBC News, the jury deliberated for more than eight hours before reaching this decision.
Konig currently faces a maximum sentence of 20 years in prison. He will be held at the O’ahu Community Correctional Center until his sentencing hearing, which is scheduled for August 13. His defense attorney, Thomas Otake, has indicated that the defense intends to appeal the ruling.
Details of the March 2025 Incident
The attack occurred on March 24, 2025, while the couple was hiking on an Oahu trail to celebrate Arielle Konig’s birthday. Prosecutors presented evidence that the attack was motivated by the doctor’s distress after learning about his wife’s alleged relationship with a coworker. According to reports from WTAE and US Magazine, the assault involved several violent acts:
- Pushing Arielle Konig toward the edge of a cliff.
- Striking her with a rock.
- Attempting to stab her with a syringe.
The violence only ceased when two other hikers heard Arielle screaming and intervened.
Contrasting Defense and Prosecution Arguments
The trial featured sharply contrasting testimonies from the husband and wife. The prosecution argued that the doctor’s actions were a targeted attack stemming from jealousy. In contrast, the defense claimed that Arielle Konig had attacked her husband first and that Gerhardt Konig struck her with the rock in self-defense.
