Yes, he was found to be in a state of delusion….one that was brought on by extreme fear. The state psych witness confirmed for the jury it was right for them to accept Simring’s conclusions that the delusions were brought on by LK’s actions.
Just because a jury is charged to find things a certain way doesn’t mean they always do. That is the basis for jury nullification. One way is for a jury to completely disregard jury instructions on how to find a verdict and do their own thing. For all you know, they thought he was straight up NG on all charges but felt obligated to ensure he got mental health treatment for the damage LK did to him and that is why they came up with NGRI.
