9 Shocking Claims from Hawaii Doctor on Trial for Wife's Murder Plot

Ariel Koig testified that her husband, Ghart, attacked her on a mountaintop in Oahu on her birthday. She recounted Ghart telling her, 'Shut the up. Nobody's going to hear you out here. Nobody's coming to save you,' and 'You're done. We're done with you. We don't need you anymore. You're done. You're done.' She claimed he then started hitting her with a rock after a brief pause when she mentioned their kids and his family.

Ariel's direct testimony in court. Her recollection of Ghart's statements during the attack and the rock assault.

Ghart Koig's oldest son, Emil, from a previous marriage, testified for the prosecution. He stated that Ghart called him via FaceTime, saying he wouldn't be returning to Maui, to take care of the younger kids, and that Ariel had been cheating on him and he 'tried to kill her.' Ghart later acknowledged in court that the word 'kill' likely came up and that Emil could have gotten that impression, but denied intent.

Emil's testimony about the FaceTime call and Ghart's statements. Ghart's cross-examination where he admits the word 'kill' was used.

Ghart Koig testified that Ariel was the aggressor. He claimed she shoved him towards the cliff edge, then pulled him to the ground, wrapped her leg(s) around him, grabbed his testicles, and repeatedly hit him with a rock. He stated he wrestled the rock from her and hit her twice in the head in self-defense because he could not safely retreat while she held his testicles.

Ghart's direct testimony detailing Ariel's alleged actions: the shove, pulling him down, holding his testicles, and hitting him with a rock. His claim of hitting her twice in self-defense.

The prosecution challenged Ghart's narrative, portraying him as controlling. They highlighted his desire for Ariel to move out with their young children, quit her remote nuclear scientist job (making her financially dependent), and 'proactively give up privacy' by allowing him constant access to her communications. They also noted that Ghart had increased Ariel's life insurance by $500,000 to $1.5 million just before the incident.

Prosecution's cross-examination of Ghart regarding his demands for Ariel to quit her job, give up privacy, and his admission of increasing her life insurance. Ghart's admission of being bigger and stronger than Ariel.
