Hawaii doctor accused of trying to kill his wife found guilty of attempted manslaughter

Key Points:

• Gerhardt Konig, a Hawaii anesthesiologist, was convicted of attempted manslaughter for attacking his wife, Arielle Konig, during a cliffside hike in Honolulu in March 2025, after a jury deliberated for a day.
• Prosecutors presented evidence that Gerhardt planned to kill Arielle by pushing her off a cliff, stabbing her with a syringe, and hitting her with a rock, with the attack only stopped by two hikers who heard her cries for help.
• Gerhardt denied the charges, claiming he acted in self-defense after Arielle allegedly hit him first with a rock, and his defense argued there was no syringe found and no murder plan.
• The trial revealed marital problems, including Arielle’s emotional affair with a coworker, which Gerhardt cited as a motive, and included his testimony about calling his son to say goodbye before hiding on the mountain for hours.
• Following the incident, Arielle has filed for divorce, and Gerhardt’s defense highlighted his prior loving relationship with his wife, portraying him as struggling with infidelity rather than intending murder.
