Hawaii doctor says wife’s alleged affair sparked violent Maui hike clash — claims she attacked first

The Hawaii doctor accused of trying to kill his wife took the stand Wednesday, claiming she attacked him first in a violent struggle on a Maui hiking trail.

Gerhardt Konig is on trial for attempted murder for allegedly trying to kill his wife on March 24, 2025. On Wednesday he testified that on the day of the alleged attack, the couple had been hiking, something he said they often did together — as jurors were shown photos from the trip.

He told the court he chose the trail because it "seemed fun" after researching new hikes.
