Gerhardt Konig, a 47-year-old Maui anesthesiologist, is on trial for the attempted murder of his wife Arielle Konig during a hike on the Pali Puka trail in Oahu in 2025. Konig claims he acted in self-defense after his wife shoved him toward the cliff's edge and struck him with a rock first. Prosecutors allege Konig planned the attack and that the evidence, including testimony from his own son, contradicts his self-defense claim.

Why it matters

This case highlights the complexities of domestic violence cases, where the line between self-defense and premeditated attack can be blurred. It also raises questions about how courts should weigh circumstantial evidence and competing narratives in such high-stakes trials.

The details

According to prosecutors, Gerhardt Konig had been researching the dangerous Pali Puka trail for weeks before the incident, suggesting premeditation. However, Konig claims his wife shoved him first, causing him to fear for his life, and that he only struck her twice in self-defense after she grabbed him and hit him with a rock. The case hinges on the jury's assessment of the conflicting accounts and the physical evidence.

  • On March 24, 2025, the alleged incident occurred on the Pali Puka trail in Oahu.
  • In early December 2024, Gerhardt Konig discovered his wife Arielle had been exchanging personal messages with a co-worker, leading to months of couples therapy.
  • Gerhardt Konig booked the Oahu trip after his wife mentioned she had always wanted to visit the island.
  • Arielle Konig filed for divorce in May 2025 and is seeking custody of the couple's two children.
  • Gerhardt Konig has been held in jail since his arrest and faces a sentence of life in prison with the possibility of parole if convicted.
