The death toll from what is said to be the deadliest mass shooting in modern US history has climbed to at least 58.
More than 500 people are injured.
The shooting took place during a country music festival on the Las Vegas Strip on Sunday night.
The gunman, 64 year-old local resident Stephen Paddock died from a self inflicted gunshot wound.
Paddock shot into the crowd of concert-goers from his 32nd floor hotel room at the Mandalay Bay.
So called Islamic State later claimed that it was behind the attack, saying that Paddock had converted to Islam some months ago.
However, the Federal Bureau of Investigations (FBI) disputed this, stating: "We have determined to this point no connection with an international terrorist group."
President Donald Trump has ordered all US flags on public grounds to be flown at half-staff until sunset Friday.
The order also applies to flags at US embassies and other US facilities abroad, such as military facilities and naval vessels.
In the meantime, Las Vegas Sheriff Joe Lombardo gave an update on reports that a woman was taken into custody in connection with the shooting.
He told a news conference this morning that the woman had been located outside the United States and was not thought to have played any role.
She is believed to have lived with Paddock who used some of her identity documents to check in to the hotel.
Paddock was found with as much as 10 weapons in the hotel room from which he carried out the attack.
But his brother, who said the family was "shocked, horrified and completely dumb-founded" by the incident, told CNN that Paddock was "not an avid gun guy at all".
In an address from the White House, President Donald Trump described the attack as "pure evil". He announced he would be visiting Las Vegas on Wednesday.
Meanwhile, Russian President Vladimir Putin sent condolences to President Trump following the shooting. He wrote that the crime that took the lives of dozens of civilians is shocking in its cruelty.
