A doctor who tried to push his wife off a cliff in Hawaii was found guilty of attempted manslaughter following a contentious trial.
Gerhardt Konig, 47, was accused of trying to kill his nuclear engineer wife, Arielle Konig, on her birthday in Oahu on March 24, 2025.
Prosecutors claimed that Gerhardt pushed her near the edge of the Pali Puka Trail and beat her multiple times with a rock.
The anesthesiologist previously pleaded not guilty to second-degree attempted murder charges, claiming he acted in self-defense.
The jury convicted him of a lesser charge on Wednesday based on mental or emotional disturbance, reported ABC News.
Gerhardt’s lawyers claimed that Arielle attacked her husband first. They said the incident was a case of ‘he said, she said.’
During three weeks of testimony, Arielle said she had been trying to repair the couple’s marriage after Gerhardt found ‘flirty messages’ between her and a coworker.
She described the relationship as a three-month-long ’emotional affair’ with her coworker Jeff Miller.

The couple went hiking in Oahu last spring after Gerhardt uncovered messages of his wife’s ’emotional affair.’
‘I was apologetic,’ she testified. ‘He was obviously hurt. I was committed to my marriage, to rebuild. It felt like an affair to him. It was an emotional affair to him.’
Arielle claimed that after her husband wrestled her to the ground, he pulled out a vial and a syringe before beating her with a rock.
The defense has noted that police never found a syringe at the scene or evidence that he tried to inject his wife with any substance.
She told the court that she screamed, ‘Please help, he’s trying to kill me’ as her husband attacked her.
Arielle testified that she was treated for ‘severe scalp lacerations’ following the incident and showed picture evidence of her injuries during the trial.
Gerhardt told the court that the couple had gotten into an argument over their affair and that she struck him with a rock first before they wrestled one another to the ground.
He admitted to striking her with a rock but denied that he had any syringes. Gerhardt also dispelled accusations that he attempted to push his wife toward the cliff’s edge.

Gerhardt expressed remorse for the incident.
‘I felt horrified about what I did to her, that I had caused this to her, that I had resorted to violence against my wife, the person whom I love the most in the world,’ he said. ‘And I just kind of felt hopeless in terms of our relationship, too.’
Prosecutors claimed Gerhardt came up with a plan to kill his wife to avoid a divorce amid their marital issues.
It was also revealed that Gerhardt stood to gain $250,000 from a life insurance policy in the event of Arielle’s death.
Arielle filed for divorce in May 2025 and sought full custody of the couple’s children.
Gerhardt has been in jail since his arrest in March 2025, roughly eight hours after he attacked his wife. His medical staff privileges at Maui Health were revoked.
His sentencing is scheduled for August 13.
