The Mandalay Bay security guard who disappeared last week moments before he was scheduled to break his silence in television interviews has not been heard from since he went to a walk-in health clinic, his union president said. 
 
 David Hickey of the Security, Police, and Fire Professionals of America (SPFPA) told reporters Friday that he got a text the night before saying Jesus Campos was taken to a UMC Quick Care facility, though he did not specify where or whom the text came from. 
 
 A spokesperson at the UMC Quick Care, which has eight locations throughout the Las Vegas area, told Fox News on Monday that they had "heard nothing" about Campos visiting them. 
 
 Multiple requests from Fox News for SPFPA to comment on the matter were not returned Monday. 
 
 Hickey said he was meeting with MGM officials Thursday afternoon in the hours before Campos’ scheduled television appearances, including one with Fox News.

 But when the meeting ended, Campos had fled. 
 
 "For the past four days he's been preparing ... we had a meeting with MGM officials, and after that meeting was over, we talked about the interviews, we went to a private area, and when we came out, Mr. Campos was gone," Hickey told reporters, according to Fox 5 Las Vegas. 
 
 Hickey said Campos had requested to go public and wanted to tell his story and move on from the Oct. 1 shooting investigation. Police say he was shot just before the crazed gunman killed 58 at music festival on the Las Vegas Strip – though the sequence of events is still in dispute. 
 
 Campos was last photographed in public on Oct. 10, accepting an “SPFPA Hero Award” for bravery in the line of duty, while dining with Hickey and others at a high-end Vegas steakhouse. But soon afterward, investigators said that the security guard was shot before the massacre, raising questions about whether the hotel did enough to prevent the bloodshed. 
 
 Hickey has said that before he vanished, Campus was looking forward to telling his side of the story. 
 
 "Right now I'm just concerned where my member is, and what his condition is. It's highly unusual,” Hickey said Friday. “I'm hoping everything is OK with him and I'm sure MGM or the union will let (media) know when we hear something," he said.

 Jesus Campos, the security guard injured in the Las Vegas shooting and lauded by authorities as an "absolute hero" for his efforts assisting police officers, has apparently disappeared. 
 
 In recent days, Campos has fallen off the radar of union leaders, backed out of media interviews, and sparked concern from neighbors who say they have no idea where he is. 
 
 Campos was shot in the leg on October 1 as he approached the door of Stephen Paddock's hotel suite on the 32nd floor of the Mandalay Bay Resort and Casino shortly before Paddock opened fire on thousands of concertgoers attending the Route 91 Harvest festival across the street, according to the latest information from Las Vegas authorities. The massacre ultimately left 58 people dead and hundreds of others injured. 
 
 Campos' disappearance comes amid a wide-ranging investigation into the shooting that has so far yielded more questions than answers and prompted a proliferation of conspiracy theories. Investigators have still not determined a motive for Paddock's deadly rampage, and Las Vegas authorities have changed their version of the shooting's timeline multiple times. 
 
 Officials said Campos was "absolutely critical" to the police response to the shooting by notifying his dispatch immediately and advising officers as they arrived. 
 
 Yet as union leaders sought to coordinate interviews between Campos and multiple news outlets, Campus suddenly vanished. 
 
 David Hickey, the president of the Security, Police, and Fire Professionals of America union, told media that he was with Campos in a Las Vegas hotel suite on Thursday, ahead of scheduled interviews with CNN, ABC, NBC, CBS, and Sean Hannity's show on Fox News. 
 
 But Hickey said Campos abruptly left the suite while Hickey was meeting in a separate room with representatives from MGM Resorts, the Mandalay Bay's parent company. Another union member told Hickey that Campos was taken to a health clinic, but Hickey was unable to reach him. 
 
 "We have had no contact with him," Hickey told the Los Angeles Times, adding: "Clearly, somebody knows where he is." 
 
 A representative for UMC Quick Care, where Hickey said he was told Campos went, told Fox News they hadn't heard anything about the security guard visiting any of the clinic's eight locations in the Las Vegas area. 
 
 When Times reporters visited Campos' reported address over the weekend, they found an armed private security guard, who declined to say who had hired him, and three "no trespassing" signs on the fence and house. 
 
 "Nobody knows where he is," Campos' neighbor Jaime Ruano told the Times, adding that Campos was "a hero." 
 
 On Friday, Sheriff Joe Lombardo of the Las Vegas Metropolitan Police Department told media that Paddock most likely shot Campos around 10:05 p.m., moments before Paddock opened fire on the crowd of concertgoers through the smashed-out windows of his 32nd-floor suite. 
 
 Days earlier, Las Vegas authorities said Campos had been shot at 9:59 p.m., prompting speculation over why six minutes had supposedly elapsed between that shooting and when Paddock carried out his massacre. In his Friday news conference, Lombardo said that the 9:59 p.m. timestamp had been derived from a "human entry into a security log" and that the information was no longer considered accurate. 
 
 Lombardo also assailed accusations that law-enforcement officials were either covering up details of the shooting or had been mistaken because of ineptitude. 
 
 "In the public space, the word 'incompetence' has been brought forward, and I am absolutely offended with that characterization," he said. 
 
 Las Vegas authorities have since sought to shut down speculation about Campos' role in the shooting. 
 
 "[Campos] is not missing. He's not under arrest," Larry Hadfield, a Las Vegas police officer, told the fact-checking website Snopes. "We tell people what we know. If they don't believe it but they're going to believe whatever website, then I don't know what else to tell you."
– He's the man everybody wants to speak with in regard to the Las Vegas shooting, but security guard Jesus Campos is apparently not interested. If Campos hoped this would deflect attention, it seems to be having the opposite effect. With headlines declaring that he has "vanished,"—see here and here—and even "mysteriously vanished," the myth-debunking website Snopes decided to dig in. Its conclusion: There's a world of difference between "vanishing" and merely withdrawing from the public eye, and it puts Campos in the latter category. Campos "is not missing," a Vegas police officer tells the website, sounding frustrated at some wild conspiracy theories surfacing. "He’s not under arrest." Campos is the security guard who was shot by Vegas gunman Stephen Paddock on the 32nd floor of the Mandalay Bay hotel. Police initially said Campos had been shot in the hallway outside Paddock's room six minutes prior to Paddock's larger shooting spree—the unarmed Campos was praised as a hero—but authorities later revised the timeline to say that he had been shot about the same time Paddock began shooting at concert fans. Campos was going to address his role and any interaction with Paddock last Thursday in a spate of media interviews, but he abruptly canceled, and Campos' union president (who was helping coordinate the interviews) says he was told only that Campos ended up in a walk-in medical clinic. Reporters say a security guard is now parked outside Campos' home, and neighbors haven't seen him. "He's a hero,” one neighbor tells the Los Angeles Times, “and nobody knows where he is.”
