The New York Times has reported that the girlfriend of the Las Vegas gunman, Marilou Danley, has arrived back in the US.
Ms Danley, 62, was overseas at the time of the shooting, which saw Stephen Paddock kill 59 people and injure over 500 from a Las Vegas hotel.
She is considered a 'person of interest' in the investigation of the attack, according to Sheriff Joseph Lombardo of the Las Vegas Metropolitan Police Department. She has not been charged with any crime, and the term 'person of interest' does not necessarily indicate that the person is suspected of committing a crime.
It is unclear what knowledge - if any - Ms Danley had of Mr Paddock's plan.
Ms Danley was met at Los Angeles International Airport by authorities after her return from Manila.
