LOS ANGELES (CBSLA/AP) — The Las Vegas shooter’s girlfriend arrived at Los Angeles International Airport Tuesday night and was met by federal agents at the airport for what is expected to be intense questioning.

Investigators are taking a harder look at Marilou Danley and what she might have known about the attack at the country music festival on Sunday.

Clark County Sheriff Joseph Lombardo said Danley is considered a “person of interest” after her boyfriend, Stephen Paddock, opened fire from his hotel room, killing 59 people at a musical performance and injuring over 500 others.

“We anticipate some information from her shortly,” Lombardo said.

A law enforcement official said Danley arrived at Los Angeles International Airport Tuesday night and was met by FBI agents.

The official wasn’t authorized to publicly discuss the matter and spoke to The Associated Press on condition of anonymity.

Danley, 62, was out the country at the time of the shooting and in the Philippines on Tuesday.

The high-stakes gambler and retired accountant who opened fire on the concertgoers, killing 59, and then taking his own life, had transferred $100,000 to the Philippines in the days before the attack, a U.S. official said.
