A Hawaii anesthesiologist, Gerhardt Konig, 47, has been convicted of attempted manslaughter in connection with an alleged attack on his wife during a hiking trip in March 2025. The Honolulu jury deliberated for a day before returning the verdict, which carries a maximum sentence of 20 years in prison. Konig was initially charged with second-degree attempted murder but was found guilty of the lesser offense, which includes the element of extreme mental or emotional disturbance.
Prosecutors alleged that Konig planned to kill his wife, Arielle Konig, during a birthday trip to Honolulu. They claimed he tried to push her off a cliff, stab her with a syringe, and strike her with a rock before two hikers intervened. Deputy prosecutor Joel Garner argued that Konig had multiple backup plans to ensure his wife's death. However, Konig’s defense maintained that he acted in self-defense after his wife allegedly attacked him first with a rock.
The trial, which lasted three weeks, featured contrasting testimonies from both Konig and his wife. Arielle Konig testified that she believed her husband wanted to render her unconscious before pushing her off the cliff. She suffered critical injuries and has since filed for divorce. Witnesses corroborated her account, and prosecutors noted that the attack ended only when hikers saw the assault and intervened. Konig fled the scene and was arrested after a six-hour manhunt.
Defense attorney Thomas Otake argued that the case was a matter of "he said, she said" and questioned the prosecution's evidence. He suggested that if Konig had intended to kill his wife, he would have used the syringe first rather than engaging in a physical struggle. The defense also highlighted Konig’s testimony that he was devastated by his wife’s emotional affair with a co-worker, which occurred three months before the incident. Konig claimed his wife minimized the affair and refused to take accountability.
Sentencing is scheduled for August 13, 2026. Konig’s legal team has confirmed plans to appeal the verdict.
