There’s no doubt John Joseph Delling knew what he was doing. His carefully planned 2007 crime spree lasted weeks, covered 6,500 miles and culminated in two people dead and one seriously wounded.

He had his reasons, too. Delling, then 21, had become “a type of Jesus,” he later explained, and the men he attacked, two of them former classmates he had not seen in years, were stealing his “energy.” An MRI of his brain would have revealed the damage the men had already caused, he told authorities.
