Investigators are taking a harder look at the Las Vegas shooter's girlfriend, with the Clark County sheriff naming her a "person of interest".
A law enforcement official says the girlfriend of Stephen Paddock has arrived in the US and was met by federal agents at Los Angeles airport.

Authorities are trying to determine why Paddock, 64, killed 59 people in the deadliest mass shooting in modern US history.
They have been speaking with girlfriend Marilou Danley, 62, who was out the country at the time of the shooting and in the Philippines.
Authorities today released police body camera video that showed the chaos of the attack on Sunday night (local time) as officers tried to figure out the location of the shooter and shuttle people to safety.
Amid sirens and volleys of gunfire, people yelled "they're shooting right at us" while officers shouted "go that way!"
Clark County Undersheriff Kevin McMahill said the shooting spanned between nine and 11 minutes.
Paddock, a high-stakes gambler and retired accountant,killed himself before police stormed his 32nd-floor room of the Mandalay Bay Resort and Casino.
Paddock transferred $100,000 to the Philippines in the days before the shooting, a US official told AP.
Investigators are still trying to trace that money and also looking into a least a dozen financial reports over the past several weeks that said Paddock gambled more than $10,000 per day, the official said.
