The story seemed straightforward: The unarmed security guard approached Stephen Paddock's room on the 32nd floor of the Mandalay Bay Resort and Casino, distracting the gunman and potentially saving lives. With a gunshot wound to his leg, he helped point officers to the gunman's location and stayed behind to evacuate hotel guests. He was hailed a hero by many, even as the story changed. Twice. Now, the man that many want to honor and who can help bring clarity about the timeline of the shooting has vanished from the public eye, less than two weeks since the Oct. 1 massacre, which left 58 people dead and more than 500 others injured. David Hickey, president of the Security, Police, and Fire Professionals of America union, said it had been four days since he last saw Jesus Campos. We have had no contact with him. Clearly, somebody knows where he is," he said. Hickey said he was with Campos on Thursday, coordinating a series of interviews that the guard was scheduled to give about the attack. Hickey said he was attending a meeting with MGM representatives in one room of the suite as Campos waited with a security guard - hired by MGM - and another union member in the living room. When the meeting ended about 2 p.m., Hickey said Campos was no longer in the room. "When I got in touch with the other union member, I was told Campos was taken to the Quick Care" health clinic, Hickey said. He didn't hear from the guard afterward and announced to a scrum of reporters that night that Campos had canceled interviews.
