A Hawaii anesthesiologist accused of trying to murder his wife on a cliffside hike has been convicted of the lesser charge of attempted manslaughter. Gerhardt Konig, 47, was found guilty by a Honolulu jury of attempting to kill his wife Arielle during a trip to Oahu last year, but the jury cited an 'emotional disturbance' related to his wife's affair as a mitigating factor, reducing the charge from attempted murder.

Why it matters

The case highlights the complexities of domestic violence cases, where emotional factors can play a significant role in how charges are ultimately decided. It also raises questions about the dangers of popular but risky hiking trails in Hawaii that remain open despite safety concerns.

The details

Prosecutors said Konig planned to kill his wife during a weekend trip to Honolulu for her birthday in March 2025, after learning of her relationship with a coworker. They alleged he tried to push her off a cliff and stab her with a syringe, and when that didn't work, he struck her with a rock. The attack was interrupted by two hikers who heard her cries for help. Konig testified that his wife hit him first with a rock, and he hit her back in self-defense.

  • In March 2025, Gerhardt and Arielle Konig went on a hike on the Pali Puka trail in Honolulu that ended with Arielle bloodied and claiming her husband tried to kill her.
  • The trial started in March 2026, nearly a year after the incident on the trail.
  • The jury returned its verdict on April 8, 2026.
