The Las Vegas gunman's girlfriend returned to the US overnight after a week-long trip abroad and was met by investigators seeking to question her for clues to what drove Stephen Paddock to slaughter 59 people from his high-rise hotel suite.

More than two days after the deadliest mass shooting in modern US history, the question of why someone with no known record of violence or crime would open fire on a country music festival was unanswered.
Paddock's girlfriend, Marilou Danley, 62, who was in the Philippines at the time of the bloodbath, was met by FBI agents at the Los Angeles airport according to a law enforcement official.
Sheriff Joseph Lombardo, who has called Danley a "person of interest" in the attack, said that "we anticipate some information from her shortly" and that he is "absolutely" confident authorities will find out what set off Paddock.
