Maui Doctor Gerhardt Konig on Trial for Attempted Murder of Wife
A Maui anesthesiologist is currently facing second-degree attempted murder charges after an alleged attack on his wife during a birthday hike in Honolulu. Gerhardt Konig, 47, took the stand this week to testify in his own defense, presenting a narrative that sharply contradicts the claims made by prosecutors and his wife, Arielle Konig.
The Incident at Pali Puka Trail
The events in question occurred on March 24, 2025—Arielle Konig’s birthday. The couple had traveled from their home in Maui to a trail near Honolulu. According to court testimony, a violent encounter took place on the Pali Puka Trail.
Gerhardt Konig testified that the attack was an act of self-defense. He claimed that following an argument regarding an emotional affair Arielle had with a co-worker, she attempted to push him from a cliff. Konig testified that during the subsequent scuffle, his wife grabbed him by the testicles and struck him in the head with a rock. He stated that he eventually wrestled the rock away and hit her twice with it.
Conflicting Accounts and Evidence
The defense’s version of events differs significantly from the prosecution’s case. Prosecutors allege that Gerhardt Konig pushed Arielle toward a cliff before attacking her with both a rock and a syringe. While the prosecution maintains he had a syringe during the encounter, Konig denied this under oath.
During cross-examination, jurors were presented with graphic side-by-side photos documenting Arielle Konig’s injuries, including:
- A bloody head and facial injuries.
- Injuries to her hand.
- The use of a neck brace and head bandages.
Following the incident, Konig testified that he continued up the trail in a daze and contacted his son via FaceTime. He admitted to telling his son he planned to accept his own life, though he denied telling him that he had tried to kill Arielle.
Prosecution’s Theory of Motive
Prosecutor Joel Garner has outlined a motive based on marital strife and control. The prosecution alleges that Konig confronted Arielle about an affair with a married coworker and pressured her to quit her job as a nuclear engineer and leave their home in Kahului. Prosecutors claimed Konig demanded sex every other day, a claim Konig denied during his testimony.
