A Maui anesthesiologist, Dr. Gerhardt Konig, on trial for allegedly trying to murder his wife during a hike in Honolulu, testified in his own defense, claiming he was acting in self-defense. The incident occurred on March 24, 2025, coinciding with his wife Arielle Konig’s birthday.
Prosecutors accuse Dr. Konig of attempting to push Arielle off a cliff and then assaulting her with a rock. During his testimony on April 2, 2026, Dr. Konig described how his wife allegedly grabbed his wrists, threw herself to the ground, and struck him with a rock first. He said he reacted “in the heat of the moment” to defend himself.
Prosecutors challenged this account, suggesting Dr. Konig’s actions were motivated by anger after discovering text messages he believed indicated an affair. However, Dr. Konig denied being angry, stating he was merely upset, not mad, when confronting his wife.
Arielle Konig, who was critically injured but survived, has filed for divorce and testified last week that her husband tried to stab her with a syringe before striking her with a rock. Witnesses, including nurses Amanda Morris and Sarah Buchsbaum, corroborated her testimony describing the attack and the extent of her injuries, with Buchsbaum noting Arielle’s face was covered in blood.
Dr. Konig expressed remorse for Arielle’s injuries during his testimony. His 19-year-old son Emile referred to his father as “the defendant” and recounted a FaceTime call shortly after the incident in which Dr. Konig said he would not return to Maui and accused Arielle of infidelity, adding that he had tried to kill her.
Dr. Konig denied any intent to harm his wife during his testimony. Before his arrest, he worked as an anesthesiologist with the Anesthesia Medical Group in Hawaii and had professional experience at the University of Pittsburgh Medical Center as an anesthesiologist and assistant professor.
If convicted of second-degree attempted murder, Dr. Konig faces a possible life sentence.
