Gerhardt Konig, the Hawaii anesthesiologist on trial for the attempted murder of his wife Arielle Konig, told a jury that he looked through her phone and downloaded her messages in the months leading up to the alleged attack.

According to testimony in court, the couple was navigating a shaky marriage in the months leading up to the incident due to what Gerhardt believed was an affair Arielle had with her co-worker.

In a temporary petitioning order filed immediately after the alleged attack, Arielle accused of Gerhardt of having “extreme jealousy,” trying to control her and sexually abusing her in the months before.

During cross-examination this week, Gerhardt told the jury after he suspected Arielle of an affair in late 2024, he went into “detective mode” and snooped around her phone and communications with the co-worker.

In October 2024, he testified during cross-examination, he became “suspicious” of Arielle’s communication with the co-worker and eventually logged into her Whatsapp account to see her messages.

He told the jury that on at least one occasion, he was logged into her account for a period of 48-hours and monitored some of the messages “as they were being sent.”

He also downloaded some of her Whatsapp chat messages and and took screenshots of her chats, he testified, adding that he “took notes” on the messages he saw, and calculated how long she was on the app.

Later in his testimony, Gerhardt said he also ended up looking through her emails, “mostly with her consent.”

Arielle said in court last week she’d had an “emotional affair” with the co-worker. At the time of the alleged attack, she said, they were working through this bump in their marriage.

The high-profile trial has so far seen testimonies from Arielle herself, her stepson and Gerhardt’s son Emile Konig, a first responder and a witness.

 

Arielle testified Gerhardt told her, “Nobody’s coming to save you,” as he tried to inject her with an unknown substance and attempted to drag her to the edge of the cliff. He then allegedly bashed her head with a rock, she told the jury.

 

Emile testified earlier this week that Gerhardt called him on FaceTime after the alleged attack, with blood splatters visible on him, and said he’d “tried to kill” Arielle.

Gerhardt also claimed he attacked Arielle in self-defense after she allegedly attacked him; Arielle has never been charged in connection to his claims of assault.

 

Emile testified during cross-examination that Gerhardt made no claims of self-defense during that call immediately after the alleged attack.
