A doctor on trial for attempted murder laughed on the stand as he described how his wife grabbed his testicles during a struggle at a Hawaii beauty spot. Gerhardt Konig, 47, admitted to striking his wife Arielle, 37, with a rock at an Oahu trail in March 2025, but claims he acted in self-defence.
Testifying on Wednesday, the anaesthesiologist told the jury that his wife pushed him from behind after an argument about her affair with a co-worker. He said she then grabbed his testicles and hit him with a rock, prompting him to wrestle the rock away and strike her twice. 'I try to free my testicles when I get both hands free,' Konig testified, adding with a laugh: 'Everything happened really quickly when she grabbed my testicles.'
Konig's wife, nuclear engineer Arielle Konig, previously testified that her husband forcefully grabbed her arms, pushed her toward a cliff, tried to inject her with a syringe, and beat her with a jagged rock. The prosecution alleges attempted murder, while the defence maintains self-defence.
During his testimony, Konig broke down in tears recalling a FaceTime call with his son Emile after the attack, saying he planned to take his own life. 'I decided to jump,' he said. 'He saved my life that day, but I put him in this position where he thinks I tried to kill her.'
Konig told the court he and Arielle met on eHarmony in 2016, married in 2018, and moved to Hawaii in 2022 for a 'safer' environment for their children. He became suspicious of an affair in December 2024 after noticing 'red flags' and unlocked her phone to find WhatsApp messages with co-worker Jeff Miller dating back to June 2024.
The trial continues.
