Hawaii Doctor on Trial for Attempted Murder After Birthday Hike Attack

Arielle Konig testified on Tuesday in the attempted murder trial of her husband, Dr. Gerhardt Konig, recounting a violent incident that occurred exactly one year ago during a birthday hike on the Pali Puka Trail in Oahu, Hawaii. The anesthesiologist is charged with second-degree attempted murder after allegedly trying to kill Arielle by pushing her toward a cliff, attempting to inject her with a syringe, and striking her head with a rock. The couple was celebrating Arielle’s birthday when the attack took place on March 24, 2025.

During her testimony, Arielle described how the altercation began after her husband asked her to take a selfie near the cliff’s edge. Feeling uneasy, she asked him to move so she could pass safely, but Gerhardt Konig grabbed her forcibly by the arms and pushed her back toward the cliff, repeatedly telling her to “get back over there.” She initially thought he was joking but soon realized the danger and tried to hold onto trees and shrubs to avoid falling. She testified that her husband climbed on top of her, brandishing a syringe and ordering her to hold still. She managed to fend off the syringe by screaming, biting his forearm, and squeezing his testicles.

Arielle further testified that after the syringe attempt failed, Gerhardt Konig began hitting her head and face with a rock while telling her that she was “done” and that no one would come to save her. She continued to scream until a nearby hiker, nurse Sarah Bucksbom, called 911. Bucksbom testified that Arielle’s face and head were covered in blood when she found her. Arielle showed the jury a large scar on her scalp as evidence of the injuries she sustained. She also revealed that the attack occurred three months after her husband discovered she had been involved in an emotional affair with a co-worker. The couple had sought counseling and appeared to be working on rebuilding trust before the incident.

Gerhardt Konig, who worked with the Anesthesia Medical Group in Hawaii and previously at the University of Pittsburgh Medical Center, has pleaded not guilty. His defense attorney argued that the doctor acted in self-defense, claiming Arielle attacked him first after he confronted her about the affair. The attorney also referenced a phone call Gerhardt made to his 19-year-old son after the incident, in which he expressed remorse and suggested he was contemplating suicide. Prosecutors, however, described the call as a confession, citing Gerhardt’s statement that he tried to kill Arielle but she escaped. The trial continues, with the possibility that Gerhardt or his son may testify. If convicted, Gerhardt Konig faces a potential life sentence.
