Robert McIntosh, a realtor with Century 21 in North Pole, was shot four times, according to Shane Nicholson, who answered the phone at McIntosh's office. 

Nicholson says McIntosh underwent surgery and is stable; he took three shots to the chest and one in the arm. 

The shooter has been identified as 64-year-old Stephen Paddock, according to Clark County Sheriff Joseph Lombardo. Paddock was found dead in a hotel room with as many as 10 firearms. 

President Donald Trump called the shooting "an act of pure evil" in a press conference Monday morning. 

The U.S. Homeland Security Department says there is no "specific credible threat" involving other public venues in the U.S. after the shooting. 

The Islamic State of Iraq and Syria (ISIS) claimed on Monday that Paddock was acting on behalf of the group but offered no evidence. The FBI has determined no connection to an international terrorist group. 

Monday morning, Alaska Governor Bill Walker announced that all Alaska state flags will be flown at half-staff through the end of the week as the "nation mourns the loss of life in the tragedy in Las Vegas". 

"This is a heartbreaking and horrific tragedy," Governor Walker said in a statement. "Donna, Byron, Toni and my prayers and condolences are with the victims and their families."

President Trump also declared that American flags will fly at half-staff on all public buildings and grounds, all military posts and naval stations, and on all naval vessels of the federal government in the District of Columbia and throughout the United States and its territories and possessions until sunset Friday.
