Las Vegas shooter's girlfriend back in US; FBI to question her

Las Vegas

LAS Vegas shooter Stephen Paddock's girlfriend has returned to the United States and was met by FBI agents eager to hear whatever she might know about the motive behind the worst mass shooting in US history which left 58 people dead and more than 500 wounded.

Although the FBI wants to talk to her, Marilou Danley, 62, is not in custody - she is classified as a "person of interest" to investigators - and is free to go wherever she wants, US media reported after her arrival on Tuesday evening in Los Angeles.
