She was sent away.

Danley was slated to return to the U.S. Wednesday to discuss the mass murder. Ms Danley, 62, was not with him when he checked into the Mandalay, officers said.

"I understand USA authorities have ruled out Australian Marilou Danley as a person of interest".

"If you have any concerns for the welfare of family and friends in the Las Vegas area, you should attempt to contact them directly", a Department of Foreign Affairs and Trade spokeswoman told AAP.

"There is no reason we can imagine why Stephen would do something like this", Paddock said."We have no idea how this happened".

Marilou Danley flew out of Manila's global airport on Tuesday night for Los Angeles, immigration bureau spokeswoman Maria Antoinette Mangrobang told AFP.

Authorities have yet to identify a motive for the shooting, and said initially there was no evidence of any connection to worldwide terrorism.

Mangrobang added Danley had arrived in the Philippines from Tokyo on September 15.

When asked why the Federal Bureau of Investigation was not bringing her back to the U.S. from the Philippines the sheriff replied: "That is occurring".

Las Vegas Sheriff Joseph Lombardo told reporters earlier on Tuesday that Ms Danley was "a person of interest" and her United States arrival meant a "substantial amount" of information on Paddock's potential motives would emerge in the next 48 hours.

In the last three years alone, more than 200 reports about Paddock's activities, particularly large transactions at casinos, have been filed with law enforcement authorities, ABC News was told.

ISIS issued two claims for Paddock's attack on its news wire, Amaq, and followed those briefings with an official statement, Smith noted.

The police have also provided more information on the suspected shooter, Stephen Paddock.

A mass shooting took place on October 1, 2017, at the Route 91 Harvest country music festival on the Las Vegas Strip in Paradise, Nevada.

His typically quiet community is now overrun with police and reporters and streets are blocked off, Lipani said.

Danely lived in Australia for a number of years.

"Given the local authorities are still investigating the incident, we can not comment further on these reports".

A gunman who shot dead at least 50 people at a pop concert in Las Vegas was a member of the Islamic State group, media linked to the militants has claimed.

"There are reports her ID was used for booking the hotel or some such detail". It's unclear when the couple met. Records show that Paddock resided at 1372 Babbling Brook Court in a home he purchased in 2015. She once worked at the Atlantis Casino Resort and Spa in Reno, which said Danley left the company "several years ago".

The children of her former husband, Geary Danley, spoke out in response to the gun massacre. Eyewitnesses said that they were horrified to see what was happening. My Thoughts and prayers go out to everyone involved tonight.

"Our family doesn't know Stephen Paddock, and has no knowledge of Marilou's relationship with Mr. Paddock".
