What evidence revealed Logan Barclay's guilt in Kirsten Hansen's murder?

District Attorney Jason Sanders details how Logan Barclay repeatedly lied to investigators, changing his story multiple times during police interviews. Initially, Barclay claimed he hoped Kirsten was just with friends, but evidence revealed he had lured her to the woods with a gun, shot her in the stomach, and left her body to be found by joggers or animals. Sanders emphasized Barclay's calculated actions - hiding evidence including Kirsten's phone, establishing a concrete plan, and refusing to acknowledge his guilt despite overwhelming evidence. This calculated behavior led Sanders to describe Barclay as the 'dungeon master' who meticulously orchestrated the entire crime.
