Hawaii doctor learns fate after prosecutors say jealousy drove him to attack wife on cliffside hike

Hawaii anesthesiologist Gerhardt Konig has been convicted of attempted manslaughter based upon extreme mental or emotional disturbance after prosecutors said he tried to kill his wife in a brutal, bloody cliffside attack fueled by suspicions of an affair.

Jurors in the case were shown graphic police body camera video of Konig’s wife covered in blood, along with the rock prosecutors say he used to repeatedly bash her head, as they weighed explosive testimony about what unfolded on a remote Oahu hiking trail on March 24, 2025.

Prosecutors argued the attack was driven by jealousy and betrayal, pointing to what they described as a growing fixation on his wife’s alleged infidelity in the months leading up to the incident.

A forensic examiner testified investigators recovered Reddit searches and posts from Konig’s laptop focused on cheating, anger and divorce — including threads titled "Lying again," "It’s over," and "I did a horrible thing."
