Hawaii doctor accused of trying to kill his wife found guilty of attempted manslaughter

Prosecutors alleged Gerhardt Konig, 47, had planned to kill Arielle Konig during a birthday trip to Honolulu

A Hawaii anesthesiologist who was accused of trying to murder his wife on a cliffside hike last year has been convicted of attempted manslaughter, a lesser charge.

A Honolulu jury returned the verdict against Gerhardt Konig, 47, on Wednesday after a day of deliberations.

Konig had planned to kill his wife, Arielle Konig, during a weekend trip to Honolulu for her birthday in March 2025, prosecutors said. They said he tried to push her off a cliff and stab her with a syringe, and then struck her with a rock before the attack was interrupted by two hikers who heard her cries for help.

The defendant testified that it was his wife who first hit him with a rock, and he hit her back in self-defense.
