HONOLULU, HI — The attempted murder trial of a Hawaiian anesthesiologist began with prosecutors and defense attorneys presenting differing accounts of a violent clash on an Oahu hiking trail.
Gerhardt Konig, 47, is accused of attacking his wife, Arielle Konig, on a March 2026 birthday hike on the Pali Puka Trail. As per Hawaii News Now, prosecuting attorney Joel Garner told jurors that the defendant tried to push his wife off the trail, attempted to stab her with a syringe, and hit her multiple times with a jagged rock.
Evidence presented on the first day of the trial included a photograph of Arielle Konig with her head and face covered in blood. Garner said the victim shouted for help while the defendant repeatedly struck her in the head.
Defense attorney Thomas Otake argued that Arielle Konig attacked first. According to the defense, the defendant felt a shove and believed his wife was trying to push him off the trail.
Otake said Arielle Konig picked up a rock and hit her husband in the face. The defense attorney said the defendant reacted by grabbing the rock and hitting her twice before stopping.
Two nurses, Amanda Morris and Sarah Buchsbaum, testified they encountered the couple during the struggle. They told the court they saw the defendant on top of his wife.
The court played a 911 call placed by Buchsbaum. In the recording, as reported by KHON2, she told dispatchers a man was trying to kill a woman who was covered in blood.
“There’s a man trying to kill her. She has blood all over her face,” Buchsbaum said on the emergency call. “We heard her screaming ‘help, help, help me, help me’ and then we saw a man over her, and then she crawled out with blood on her face. He tried to kill her.”
Buchsbaum testified that she heard the woman screaming for help. She said the victim crawled away with facial injuries after the man stood over her.
The defendant wept in court as Otake described a FaceTime call Konig made to his 19-year-old son following the incident. The defense said Konig intended to say goodbye and expressed a desire to take his own life.
“He was calling him to say goodbye. He was calling him to tell him he was sorry. He was calling him to tell him he wished he was a better man,” Otake explained to the court.
Prosecutors characterized the phone call as a confession. Garner told the jury that the defendant informed his son he tried to kill his wife but she escaped.
Medical evidence is a point of contention in the case. The prosecution pointed out that Arielle Koenig was hit on the head multiple times with a sharp rock. The defense argued that Arielle Konig merely sustained a head laceration that bled heavily but was not serious.
Prosecutors and defense attorneys offered conflicting motives for the confrontation. Prosecutors said the defendant lashed out after his wife refused to take a photo during the birthday hike, while the defense claimed Arielle Konig was having an affair with a co‑worker.
Arielle Konig was expected to testify March 20. Her appearance was delayed until March 24 following a defense objection regarding a portion of her testimony. The trial is expected to go on until mid April.
Presumption of Innocence: A presumption of innocence means that any defendant in a criminal trial is presumed to be innocent until they have been proven guilty beyond a reasonable doubt in a court of law. The defendant in this case is only accused of the charges set forth in the criminal complaint. They are innocent until proven guilty.
