Gory body cam footage released of Arielle Konig being helps down the O'ahu's Pali Puka trail after being smashed in the head by a rock. It's part of the attempted murder trial of Maui anesthesiologist, Dr. Gerhardt Konig. Each side is describing O'ahu's Pali Puka trail, but have different stories of what happened there almost exactly a year ago. Arielle says her husband dragged her toward the cliff’s edge, attempted to inject her with “an unknown substance” using a syringe, and hit her “repeatedly on the head” with a rock. Konig claims he was NOT trying to kill his wife, and acted in self-defense after Arielle attacked him when he threatened to expose an alleged affair with a married co-worker. Jurors hear a witness's 911 call, and watch that body camera footage from a responding officer. Arielle's brutal injuries visible as blood pours from her head wounds. Konig's adult son is expected to testify about a video call his father made after the attack that prosecutors are calling a confession.
