As Bobby lifted his 'gooney stick' axe handle above his head and swung it down with brute force for the third time, he licked his lips as the weapon smashed again into the limp head of his train boxcar companion. He savoured the moment as he watched the frantic eyes of his victim stammer to a halt and slowly drain of life. Bobby had become exceptionally good at taking lives - the lives of those who would not be missed. This is the true story of an extremely brutal and extraordinary serial killer who plagued the United States' busy freight train tracks for some fifteen years. Over the decade and a half between 1981 and 1996, Robert Joseph Silveria Junior's horrific and truly terrifying killing spree led him to ultimately take the lives of some 28 fellow travellers until being finally apprehended.
