Gerhardt Konig, an anesthesiologist, was found guilty of attempted manslaughter in a Honolulu court after being accused of attacking his wife during a cliffside hike in Oahu.

Prosecutors alleged he assaulted Arielle Konig by trying to stab her and striking her with a rock, though the jury rejected the more serious attempted murder charge.

The defense argued he acted in self-defense, while the prosecution presented witness testimony supporting the attack claims.

Arielle Konig survived with serious injuries after hikers witnessed the incident and intervened, prompting the defendant to flee before being arrested, CBS News has reported.

Konig now faces up to 20 years in prison, and his defense plans to appeal the verdict.
