Trial ending for Hawaii doctor accused of trying to kill his wife

Key Points:

• An attempted murder trial is concluding for Gerhardt Konig, an anesthesiologist accused of trying to kill his wife, Arielle Konig, during a hike on the Pali Puka trail in Honolulu, with closing arguments expected Tuesday.
• The incident occurred in March 2025 during a birthday trip, where prosecutors say Gerhardt tried to push Arielle off a cliff, struck her with a rock, and attempted to stab her with a syringe; Gerhardt has pleaded not guilty and denies these allegations.
• Testimonies revealed marital strife, including Gerhardt’s claim of Arielle’s emotional affair, and conflicting accounts of the physical altercation on the trail, with Arielle describing a violent attack and Gerhardt asserting self-defense.
• The trail where the incident occurred is officially closed for safety reasons, but hikers often trespass; two hikers assisted Arielle after hearing her screams.
• After the attack, Gerhardt allegedly confessed to his adult son about the attempt, which he denies, and eventually surrendered to police; Arielle has since filed for divorce.
