A jury has delivered a verdict in the case of a physician from Hawaii accused of attempting to murder his spouse on a hiking trail last year.

Dr. Gerhardt Konig, 47, faced charges of second-degree attempted murder. Prosecutors claimed that the anesthesiologist assaulted his wife, Arielle Konig, near a cliff on the Pali Puka Trail on Oahu during her birthday celebration on March 24, 2025, by pushing her close to the edge and striking her multiple times with a rock.

The defense contended that Arielle Konig initiated the confrontation, asserting that Dr. Konig acted in self-defense when he struck her with the rock, framing the situation as a matter of conflicting testimonies.

Deliberations by the jury commenced Tuesday afternoon after three weeks of witness testimonies in the Honolulu courtroom.

Dr. Gerhardt Konig pleaded not guilty to the charges.

If the jury did not find him guilty of second-degree attempted murder, they would then evaluate his culpability regarding attempted manslaughter due to extreme emotional distress, first-degree attempted assault, second-degree assault, or third-degree assault.

Both Dr. Konig and his wife provided testimony during the trial, and their accounts of the hiking incident were vastly different.

Arielle Konig testified that the couple traveled from their home in Maui to Oahu to celebrate her birthday. She described their efforts to mend their marriage after her husband discovered what she termed “flirty” messages exchanged with a colleague in December 2024, which she referred to as an “emotional affair.”

During her testimony, she recounted that her husband pushed her toward the cliff’s edge. While they struggled on the ground, and he had her pinned down, he allegedly produced a syringe and vial.

Arielle further stated that Dr. Konig struck her with a rock up to ten times, believing he intended to render her unconscious to drag her over the cliff. She recalled screaming for help, stating, “Please help, he’s trying to kill me,” and that when two passersby approached, her husband “froze,” allowing her to escape.

In his defense, Dr. Gerhardt Konig testified over two days, asserting that he never meant to harm his wife and that his actions were in self-defense. He claimed that after an argument about her alleged affair, she pushed him close to the cliff’s edge and struck him with a rock first during their struggle. He admitted to hitting her with the rock while restraining her but denied possessing any syringes or attempting to pull her toward the cliff.

Dr. Konig expressed feelings of hopelessness following the incident, stating, “I just felt hopeless at that point in terms of everything,” and he was horrified by the violence he had inflicted on his wife, whom he loved dearly.

In closing arguments, prosecutor Joel Garner characterized Arielle Konig’s testimony as “straightforward” and “coherent,” stating it was supported by physical evidence from the scene, the severity of her injuries, digital communications, and witness accounts, including those of the two women who encountered the couple.

Garner suggested that Dr. Gerhardt Konig had devised a plan to eliminate his wife on the treacherous Pali Puka Trail to evade a costly divorce, dismissing the defendant’s claims of self-defense as “unbelievable.”

The prosecution also highlighted testimony from Dr. Konig’s older son from a previous marriage, who indicated that his father confessed to attempting to kill Arielle. Emile Konig recounted a FaceTime call in which his father expressed that he would not return to Maui and urged him to care for the younger siblings, admitting, “Ari, my stepmom, had been cheating on him, and that he tried to kill her.”

During the defense’s closing argument, attorney Thomas Otake emphasized that there was “reasonable doubt” throughout the case. He challenged the prosecutor’s narrative and questioned Arielle Konig’s credibility, describing her as “deceptive” and noting her deletion of messages with her colleague.

Otake contended that the conversation between Dr. Konig and his son occurred in a highly emotional context, and Emile Konig could not accurately recall the exact wording of their exchange.

Dr. Gerhardt Konig was apprehended following an extensive manhunt, according to prosecutors.

Arielle Konig testified that she required hospitalization for “severe complex scalp lacerations” and displayed scarring to the court.

In May 2025, she filed for divorce, seeking full custody of their two young children.

Since his arrest, Dr. Gerhardt Konig, who served as an anesthesiologist in Maui, has remained in custody. Following the incident, Maui Health announced that his privileges at Maui Memorial Medical Center have been suspended pending further investigation.
