A Hawaii jury has found a Maui anesthesiologist guilty of trying to kill his wife during a cliffside hike in Oahu—but stopped short of convicting on the most serious charge, NBC News reports. Dr. Gerhardt Konig was convicted Wednesday of attempted manslaughter under a provision involving extreme mental or emotional disturbance, avoiding a second-degree attempted murder conviction that could have meant life in prison. The unanimous verdict followed more than eight hours of deliberation and capped a three-week trial over the March 24, 2025, incident on the Pali Puka Trail, northeast of Honolulu. Konig, who faces up to 20 years behind bars, will be sentenced Aug. 13 and held at the Oahu Community Correctional Center until then.

Prosecutors said Konig, distraught over his wife Arielle's "emotional affair" with a co-worker, tried to shove her off a cliff, then attacked her with a syringe and a rock, stopping only when hikers came upon the struggle and called 911. Arielle testified she was told, "Nobody's going to hear you out here." Konig denied trying to inject or push her, saying he acted in self-defense after she attacked him. His attorney called the case a "she said, he said" and vowed to appeal, while Honolulu prosecutor Steve Alm labeled the verdict "a good day for the good guys."

As the AP reports, Hawaii law requires jurors to reduce the charge to attempted manslaughter if they believe the defendant acted while under the influence of an extreme mental or emotional disturbance for which there was a reasonable explanation. The jury foreperson said jurors concluded Arielle's alleged relationship with a co-worker was reasonable to cause such a disturbance. Fox News reports prosecutors painted a picture of months of obsession with the alleged relationship leading up to Konig's actions on the trail; he had used keywords including "kill," "death," "cliff," and "fall" to search for remote hiking locations.
