Episode notes
Wife Testifies About Hike Attack
- Ariel Koenig testified she was pushed toward a cliff, wrestled, and struck multiple times with a jagged lava rock during a Palipuka Trail hike.
- She described Gerhardt Koenig saying “shut the f*** up” and telling her nobody would come to save her as he was on top of her.
Prosecution's Escalation Theory
- Prosecution says sequence escalated from a syringe and vial to a jagged lava rock, implying premeditated intent to kill.
- Syringe and vial were never recovered, so prosecutors emphasize the rock blows and phone evidence to tie motive and action.
