According to a senior FBI official, authorities became suspicions by the extreme amount of gunpowder residue found on Campos’ hands and inconsistencies in his timeline of events. “We believe he killed Paddock, shot holes through the door and his own arm to produce physical evidence for his cover story, then went and lay next to the elevator,” the FBI official told CNN.
An anonymous source working on the investigation told CNN that authorities are now in possession of security footage showing Campos smuggling the firearms used in the massacre in through a Mandalay Bay loading dock in the days leading up to the event.
