Prosecutors allege that before pushing Arielle off a cliff during a hike, Gerhardt Konig threatened her, saying, “No one is going to save you.” This cruel statement was used to connect the crime to the horrific crime scene photographic evidence that was shown to the jury

Graphic body camera video and a bloodstained rock prosecutors say was used in a brutal cliffside attack were shown to jurors Wednesday as the attempted murder trial of Hawaii doctor Gerhardt Konig entered a critical new phase.

An evidence specialist and responding officers testified on the fourth day of Konig’s trial, walking jurors through the alleged attack and the immediate aftermath, including video showing Arielle Konig bloodied and disoriented.

The video played in court showed people helping Arielle, who had blood dripping down her face and a bandage on her head after she was allegedly attacked by her husband. Jurors also viewed the rock that Gerhardt Konig allegedly used to hit his wife in an attempt to force her off a cliff.

The testimony followed a dramatic day in court Tuesday, when Arielle Konig told jurors her husband attacked her during a birthday hike, tried to push her off a cliff and struck her repeatedly in the head with a rock.

“He’s trying to kill me,” she testified.

According to her account, her husband grabbed her and tried to force her toward the cliff, leading to a struggle on the ground. During that struggle, she said she saw him holding a syringe, which she knocked away.

She testified that he then picked up a rock and struck her multiple times in the head.

At one point, she said, he told her, “Nobody’s coming to save you.”

She said she fought him off, clung to vegetation to avoid going over the edge and was able to escape when two hikers intervened and called 911.

On Wednesday, prosecutors began tying that account to physical evidence.

Jurors were shown the rock investigators say was used in the attack and watched body camera video from responding officers documenting the aftermath.

Defense attorney Thomas Otake has argued the incident was not an attempted murder but an “unplanned” confrontation that escalated, suggesting the encounter has been mischaracterized.

He has pointed to strain in the couple’s relationship, including Arielle Konig’s acknowledgment of an emotional relationship with a coworker, and suggested the incident has been overstated.

Arielle Konig rejected that claim during her testimony, telling jurors, “I would call it an attack versus a scuffle.”

As the case moves forward, jurors will be asked to weigh whether the physical evidence supports prosecutors’ claims of an intentional attempt to kill or the defense’s argument that the encounter was a fight that spiraled out of control.
