Las Vegas shooter's partner returns to US

The FBI is still stumped over what motivated Stephen Paddock to commit the worst mass shooting in modern American history. But they're hopeful the gunman's girlfriend, Marilou Danley, who has just returned to the US from the Philippines, will provide them with some more answers. In an exclusive interview with Australia's Seven Network, Ms Danley's sisters said she was "sent away" by Paddock so she wouldn't interfere in his plans. US correspondent Patrice Howard is in Las Vegas and joins us with the latest news from the city.
