A Hawaii doctor was found guilty Wednesday of attempted manslaughter for assaulting his wife during a cliffside hike on Oahu in March 2025. Gerhardt Konig, 47, an anesthesiologist based in Maui, faced a three-week trial in Honolulu after being charged with second-degree attempted murder.
The jury convicted Konig of the lesser charge of attempted manslaughter based on extreme mental or emotional disturbance, which carries a maximum prison sentence of 20 years. Konig had pleaded not guilty to the more serious attempted murder charge.
According to court testimony, the incident occurred along the Pali Puka trail, a remote hiking path with steep cliffs. Arielle Konig, the victim and Gerhardt Konig’s wife at the time, testified that her husband assaulted her by attempting to stab her with a syringe and striking her head with a rock. She told the jury she believed he intended to knock her unconscious before pushing her off the cliff.
Two hikers witnessed the attack, which prompted Konig to stop and flee the scene. He was apprehended after a six-hour manhunt. Witnesses corroborated Arielle Konig’s account, describing seeing Gerhardt Konig hit her with a rock and noting her face was covered in blood. One witness called emergency services during the assault.
Arielle Konig testified that her husband was angry over her alleged affair, which she said motivated the attack. Konig’s 19-year-old son, Emile, also testified that his father admitted during a FaceTime call that he had tried to kill Arielle because of her infidelity.
Gerhardt Konig testified in his own defense, claiming he acted in self-defense after his wife allegedly grabbed his wrists, threw herself to the ground, and hit him with a rock. He denied planning to harm her and said he was upset but not angry over the suspected affair.
Prior to his arrest, Konig worked as an anesthesiologist with Anesthesia Medical Group in Hawaii and previously held a position at the University of Pittsburgh Medical Center, where he was also an assistant professor.
Konig’s defense attorney announced plans to file an appeal, citing several appellate issues and disputed judicial rulings during the trial. Prosecutors expressed respect for the jury’s decision but declined to comment on whether they were disappointed the more severe conviction was not reached.
Why it matters
The case highlights legal distinctions between attempted murder and attempted manslaughter based on emotional disturbance, which may influence sentencing and future prosecutions involving domestic violence and extreme mental states. The conviction emphasizes the judicial outcome in a high-profile domestic assault involving a medical professional and raises questions about mental health considerations in violent crimes.
