On 17^th September 2015, 56-year-old newspaper worker Edward Lowry is found stabbed to death in a parking lot in Rapid City, South Dakota. He had left a local bar just before 2am – the last known sighting of Ed before his murder. Minutes later he would be brutally beaten, stabbed and left for dead. CCTV from Ed’s route would reveal that he was deliberately targeted and later followed by his attackers. But investigators are no closer to identifying their prime suspects until a trip to a convenience store gives them the crucial breakthrough they need to prevent Ed’s murder becoming an unsolved cold case.  But can investigators track down his killers before they strike again?
