before dawn on the last Saturday of June 2013, an employee at a Toys ‘R’ Us store in upstate New York was working in the stock room, when suddenly he heard an alarm going off somewhere inside the store. He radioed his manager to turn off that alarm, but the manager didn’t respond. Another employee went to the front office to check on the manager, and they found him unconscious and bleeding from a hole in his chest. Police and paramedics responded and rushed the man to the hospital, but sadly, he was dead on arrival. The store had been locked all morning, and the four surviving employees had been working in separate parts of the store. Each of them claimed to have seen nothing out of the ordinary that morning. And all investigators had to help them find the manager’s killer was surveillance footage of a shadowy figure moving in and out of the security camera’s view
