The official was not authorized to discuss the case publicly and spoke on condition of anonymity after being briefed on the investigation.

Federal Bureau of Investigation agents interviewed Marilou Danley, Paddock's girlfriend, hoping she could provide insight into the shooting, but she has said she knew nothing of his plans or potential for such violence.
Discerning Paddock's motive has proven especially baffling as he had no criminal record, no known history of mental illness and no outward signs of social disaffection, political discontent or extremist ideology, police said.

It is unusual to have so few hints of a motive five days after a mass shooting.
Three of the police officers who closed in on Paddock's room as he turned his gun on himself told "60 Minutes" correspondent Bill Whitaker that they found the note near one of the windows Paddock had smashed out.

Paddock bought Danley a plane ticket to her native Philippines before the shooting and made sure she was there during the shooting.
On Wednesday, Paddock girlfriend's attorney, Marilou Danley, said she did not know of any plans for him to commit the massacre. TMZ's sources said that Paddock allegedly requested both his rooms be a "view rooms" that face the park.
