Lathem and Warren ambushed Cornell while he was in Lathem’s bed, prosecutors said, stabbing him more than 70 times and nearly decapitating him, they said. Then the two went on the lam, during which Lathem sent a video to his family saying “I killed him, I did do it, it wasn’t an accident, it was a mistake, the biggest mistake of my life, and I regret it with every fiber of my being,” according to Thrun.
