A Hawaii doctor is standing trial for attempted murder after admitting to striking his wife over the head with a rock at a scenic location on Oahu in March 2025.

Gerhartdt Konig, 47, has acknowledged the attack on his wife Arielle, 37, but is claiming self-defense, telling the court that she struck him first during the confrontation at the beauty spot.

According to court proceedings, the incident occurred during what prosecutors describe as a dispute over an extramarital affair. Konig's defense team is reportedly attempting to use his wife's alleged relationship with a co-worker as justification for his actions.

The case centers on the events of the March confrontation, with the prosecution arguing that Konig's actions constituted attempted murder, while the defense maintains he was acting in self-defense after being attacked first.

Details about the specific location of the incident and the extent of Arielle Konig's injuries have not been fully disclosed in available court records. The trial is ongoing as both sides present their arguments regarding the circumstances that led to the alleged assault.
