MGM Resorts International spokeswoman Debra DeShong said in a statement Tuesday that Jesus Campos will tell his story when he is ready.
MGM Resorts owns the Mandalay Bay hotel, where Paddock shot Campos before he opened fire on country music concertgoers from his 32nd-floor suite and killed 58 people.
DeShong made the statement after a representative for Campos' union said he prepared last Thursday for TV appearances but went to a health clinic instead and then disappeared.
Security, Police, and Fire Professionals of America leader David Hickey said Tuesday he last heard about Campos' whereabouts from a union member who messaged that he was with Campos.
Campos talked with police but hasn't spoken publicly about the Oct. 1 massacre.
