Gerhardt Konig was convicted of attempted manslaughter based upon extreme mental or emotional disturbance. He claimed he acted in self-defense.

In his closing argument, prosecutor Joel Garner said Gerhardt Konig was “obsessed” with his wife’s emotional affair with a co-worker when he tried to shove her from a cliff on the Pali Puka Trail, northeast of Honolulu.

When that failed, Garner said, he tried to stab her with a syringe and bashed her head with a rock. The attack ended when two hikers came upon the scene, he said.

“The only thing that got him to stop was being caught red-handed,” Garner said.
