Still reeling from the worst shooting in its modern history, the US sought on Tuesday to come to grips with the fallout of the shooting that left 59 people dead in Las Vegas.
Police searched for clues that would shed light on why a retiree with a penchant for gambling but no criminal record set up a sniper’s nest in a high-rise Las Vegas hotel and poured gunfire onto a concert below, slaying dozens of people before killing himself.
The Sunday night shooting spree from a 32nd-floor window of the Mandalay Bay hotel, on the Las Vegas Strip, killed at least 59 people before the gunman turned a weapon on himself. More than 500 were injured, some trampled, in the assault.
The gunman, identified as Stephen Paddock, 64, left no immediate hint of his motive for the arsenal of high-powered weaponry he amassed, including 34 guns, or the carnage he inflicted on a crowd of 22,000 attending an outdoor country music festival.
Paddock was not known to have served in the military, or to have suffered from a history of mental illness or to have registered any inkling of social disaffection, political discontent or radical views on social media.
US officials also discounted a claim of responsibility by the ISIS terrorist group.
“We have determined to this point no connection with an international terrorist group,” Aaron Rouse, special agent in charge of the Federal Bureau of Investigation field office in Las Vegas, told reporters on Monday.
Police said they believed Paddock acted alone but were at a loss to explain what might have precipitated it.
“We have no idea what his belief system was,” Clark County Sheriff Joseph Lombardo told reporters. “I can’t get into the mind of a psychopath.”
President Donald Trump condemned the mass shooting in Las Vegas as an “act of pure evil” and declared the nation would unite behind the survivors, but he refused to get into a new debate over gun control.
“Our unity cannot be shattered by evil, our bonds cannot be broken by violence,” the president said. “We call upon the bonds that unite us: our faith, our family, and our shared values. We call upon the bonds of citizenship, the ties of community, and the comfort of our common humanity.”
In a measured statement that was revised by aides until moments before he spoke, Trump praised the first responders who he said prevented further loss of life. He said he would visit Las Vegas on Wednesday. He offered condolences to the families of those killed, saying: “We cannot fathom their pain. We cannot imagine their loss.”
Trump, who owns a hotel in Las Vegas, told associates that he feels deep ties to the city. He said in public that his visit would be “a very, very sad moment for me … for everybody no matter where you are, no matter what your thought process.”
Although police said they had no other suspects, Lombardo said investigators wanted to talk with Paddock’s girlfriend and live-in companion, Marilou Danley, who he said was traveling abroad, possibly in Tokyo.
Lombardo also said detectives were “aware of other individuals” who were involved in the sale of weapons Paddock acquired.
Still, the closest Paddock appeared to have ever come to a brush with the law was for a traffic infraction, authorities said.
The death toll, which officials said could rise, surpassed last year’s record massacre of 49 people at a gay nightclub in Orlando, Florida, by a gunman who pledged allegiance to ISIS.
Paddock, however, seemed atypical of the overtly troubled, angry young men who experts said have come to embody the profile of most mass shooters.
Public records point to an itinerant existence across the US West and Southeast, including stints as an apartment manager and aerospace industry worker. But Paddock appeared to be settling in to a quiet life when he bought a home in a Nevada retirement community a few years ago, about an hour’s drive from Las Vegas and the casinos he enjoyed.
His brother, Eric, described Stephen Paddock as financially well-off and an avid enthusiast of video poker games and cruises.
“We’re horrified. We’re bewildered, and our condolences go out to the victims,” Eric Paddock said in a telephone interview from Orlando, Florida. “We have no idea in the world.”
Las Vegas’s casinos, nightclubs and shopping draw some 3.5 million visitors from around the world each year, and the Strip was packed with visitors when the shooting started shortly after 10 p.m. local time on Sunday (0400 GMT Monday).
Police said 23 guns were found in Paddock’s suite, along with more than 10 suitcases.
Lombardo said a search of the suspect’s car turned up a supply of ammonium nitrate, a fertilizer compound that can be formed into explosives and was used in the 1995 Oklahoma City bombing of a federal office building that killed 168 people.
Police found another 19 firearms, some explosives and thousands of rounds of ammunition at Paddock’s home in Mesquite, about 90 miles (145 km) northeast of Las Vegas, along with some electronic devices, including computers.
They also obtained a warrant to search a second house connected to Paddock in Reno, Nevada, more than 400 miles (644 km) northwest of Las Vegas.
Chris Sullivan, the owner of the Guns & Guitars shop in Mesquite, issued a statement confirming that Paddock was a customer who cleared “all necessary background checks and procedures,” and said his business was cooperating with investigators.
“He never gave any indication or reason to believe he was unstable or unfit at any time,” Sullivan said. He did not say how many or the kinds of weapons Paddock purchased there.
Lombardo said investigators knew that a gun dealer had come forward to say that he had sold weapons to the suspect, but it was not clear if he was referring to Sullivan. He said police were aware of “some other individuals who were engaged in those transactions,” including at least one in Arizona.
Investigators also want to interview Danley, who police initially described as a “person of interest” but not a suspect. She is an Australian citizen who is reported to have been born in the Philippines.
Like presidents before him, Trump marked the Las Vegas shootings by ordering the American flags at all public buildings across the nation flown at half-staff, and he observed a moment of silence on the White House lawn. Unlike his predecessor, Barack Obama, who responded to mass shootings by calling for stricter gun control measures, Trump made no mention of firearms restrictions.
