MANILA - Investigators have cleared an Asian woman of involvement in the slaughter of at least 59 people during a Las Vegas country music festival Monday, the largest mass shooting in US history.

Marilou Danley was initially described by the police as an "Asian" and "companion" of Stephen Paddock, 64, who strafed concert-goers from the 32nd floor of the Mandalay Bay.

Several IDs of Danley were recovered among Paddock's belongings. Police and public records said Paddock lived with Danley in the Nevada retirement community.

Police later confirmed that Paddock acted alone and that Danley was travelling abroad during the shooting rampage, said Dyan Kristine Miranda-Pastrana, vice consul of the Philippine Consulate General in Los Angeles, California.

"Kinlaro na po ng Las Vegas Police Department na hindi siya sangkot sa insidente kasi wala po sya sa country noong nangyari ang insidente," Pastrana told DZMM.

(The Las Vegas Police Department clarified that she was not involved in the incident because she was not in the country when the attack occurred.)

Foreign Affairs spokesperson Robespierre Bolivar, in a statement, said there is no official confirmation so far on Danley's nationality, although some of her friends claimed that she is a Filipina.

Danley described herself as a "casino professional," as well as a mother and grandmother on social media websites, according to Reuters.

Las Vegas -- whose casinos, nightclubs and shopping district draw some 3.5 million visitors every year -- is home to some 120,000 registered Filipinos, said Pastrana.

The Philippine Consulate, she said, has not received reports of Filipinos who may have been injured or killed in the shooting rampage.

"Sa recent update po, wala pa po tayong nare-receive na news na mayroon po Filipino na nadamay. Hindi pa po ma-confirm ng Las Vegas Metropolitan Police Department ang ganoong information," said Pastrana.

(In the recent update, we have not received news that any Filipino was affected by the incident. The Las Vegas Police Department cannot confirm this information yet.)

"Very concerned po sila (Filipino community), lalo na po iyung nurses and doctors natin na nagtatrabaho sa mga ospital sa Las Vegas... They are the first responders po na nag-a-assist dito sa mga nasawi at mga injured sa insidente," the official added.

(The Filipino community there is very concerned, especially the nurses and doctors working at Las Vegas hospitals. They were the first responders who assisted those slain and injured in the incident.)

Monday's pandemonium injured some 525 people. Its preliminary death toll, which officials said could rise, surpassed last year's massacre of 49 people at a gay nightclub in Orlando, Florida, by a gunman who pledged allegiance to Islamic State.

The Islamic State militant group claimed responsibility for the Las Vegas massacre, but US officials said there was no evidence of that.
