The doctor accused of trying to kill his wife while hiking in Hawaii only stopped his rock-beating, syringe-wielding attack when fellow hikers came by, according to court documents revealed Thursday.
Dr. Gerhardt Konig, a 46-year-old Maui anesthesiologist, and wife Arielle Konig were on Pali Puka Trail in Honolulu on Monday when he asked her to snap of a photo of them, according to court documents supporting his arrest.

"She mentioned that while on the trail, Gerhardt was standing close to the edge and asked her to take a selfie with him,” a Honolulu police declaration said.
"Arielle expressed that she did not feel comfortable taking a picture with him that close to the edge, so she declined and began to walk back."
Konig yelled at her to return and she refused, prompting him to push the victim into bushes, she told police.
That's when Konig picked up a rock and struck her on the head about 10 times “while also grabbing the back of her hair and smashing her face into the ground,” according to the document.
The 36-year-old wife reported to police that Konig took "out two syringes from his bag and attempt to use them on her, but she was able to get them away from him,” the police declaration said.
The attack subsided only as other hikers came upon the scene.
The first hiker, identified only as "Amanda," told police she started up Pali Pula at 10:28 a.m. Monday and less than 10 minutes into the stroll when she heard a woman screaming, "Help! Help me!' she told police.
Amanda then saw Arielle Honig on her back "with a man on top of her hitting her on the head," the court affidavit said.
"Amanda described that the man had a rock in his hand and when he saw her, he stopped and got off of the woman," according to the police narrative.
"Amanda recalled that the woman, later identified as Arielle. stated, 'He is trying to kill me. He is hitting me in the head with a rock.' "
The witness' hiking partner called 911 as Dr. Konig fled and was caught at 6:10 p.m. following a brief foot chase, officials said.
A judge set Konig’s bail at $5 million and a preliminary hearing in the attempted murder charge was scheduled for Monday.
A lawyer for Konig could not be immediately reached for comment Friday.
