A Hawaii doctor's attempted murder trial took a stark turn Tuesday as his 19-year-old son told jurors his father confessed during a FaceTime call, NBC News reports. Emile Konig testified that on March 24, 2025, the day prosecutors say anesthesiologist Gerhardt Konig tried to kill his wife on a popular Oahu trail, his father said on the call that she had been unfaithful, admitted he'd tried to kill her, and declared he wouldn't be returning to Maui. Emile said Konig, who had blood on his clothes, told him to look after his younger siblings and said he planned to jump from a cliff; Emile testified he asked him not to. He said he has not spoken to his father, whom he referred to as the defendant, since that day, Hawaii News Now reports.
Prosecutors allege Konig, 47, lured wife Arielle on a birthday hike, steered her toward a cliff on the Pali Puka Trail, then pushed her, tried to inject her with a syringe, and struck her head with a rock. Arielle testified that he told her, "Nobody's coming to save you," before she fought him off and fled when another hiker said 911 was being called. Konig has pleaded not guilty to second-degree attempted murder and claims he acted in self-defense—an account his son undercut on the stand, saying his father never mentioned defending himself during the call. Arielle is Emile's stepmother and the mother of his two younger stepsiblings, KITV reports.
