WASHINGTON — The girlfriend of Stephen Paddock, who opened fire on a country music festival in Las Vegas earlier this week, said Wednesday that she had no warning about his plans to carry out the massacre.
‘‘I knew Stephen Paddock as a kind, caring, quiet man,’’ Marilou Danley, Paddock’s girlfriend, said in a statement read by her attorney. ‘‘He never said anything to me or took any action that I was aware of that I understood in any way to be a warning that something horrible like this was going to happen.’’
Danley was out of the country when Paddock, 64, carried out his rampage, officials said. She returned late Tuesday to Los Angeles, where FBI agents interviewed her on Wednesday.
‘‘I am devastated by the deaths and injuries that have occurred and my prayers go out to the victims and their families and all those who have been hurt by these awful events,’’ Danley said.
Danley said that she left the country because Paddock bought her a ticket to visit her family in the Philippines. While there, she said, Paddock wired her money that he explained was meant to help her purchase a home for Danley and her family.
‘‘I was grateful, but honestly, I was worried, that first, the unexpected trip home, and then the money, was a way of breaking up with me,’’ she said. ‘‘It never occurred to me in any way whatsoever that he was planning violence against anyone.’’
Danley, who pledged to cooperate with authorities, is viewed by officials as a key part of the investigation into the deadliest mass shooting in modern American history. Paddock brought a small arsenal into a two-room suite on the 32nd floor of the Mandalay Bay Resort and Casino and began raining bullets on the thousands of concertgoers far below.
Authorities have described a chilling level of preparation but have been unable to discern a motive for the shooting. Paddock, who had set up cameras so he could monitor the approach by police, turned a gun on himself as a SWAT team closed in.
Danley is considered a critical witness in trying to decipher that motive, according to a person familiar with the probe. Police have described her as a ‘‘person of interest,’’ though they have not suggested that she is considered an accomplice or involved in any way.
Authorities expressed bafflement at what could have motivated the rampage. FBI Deputy Director Andrew McCabe said Wednesday he is surprised they have not found evidence pointing to the gunman’s motive yet.
‘‘There’s all kinds of things that surprise us in each one of these events,’’ McCabe told CNBC. ‘‘This individual and this attack didn’t leave the sort of immediately accessible thumbprints that you find on some mass casualty attacks. . . . We look for actual indicators of affiliation, of motive, of intent, and so far we’re not there. We don’t have those sort of indicators.’’
McCabe said agents have been reconstructing ‘‘the life, the behavior, the pattern of activity of this individual and anyone and everyone who may have crossed his path in the days and the weeks leading up to this horrific event.’’
So far, he said, investigators have not had any problems accessing the gunman’s computer electronic devices.
Amid a backdrop of anguish and questions, President Trump on Wednesday headed to Las Vegas to visit with survivors of the attack and law enforcement personnel. He echoed authorities in saying that they have not identified a motive.
‘‘Not yet,’’ Trump said during remarks to reporters. ‘‘We’re looking. I can tell you, it’s a very sick man. He was a very demented person. We haven’t seen that yet, but you will know very soon if we find something. We’re looking very, very hard.’’
Trump declined to speak about gun violence in America during his remarks. When he appeared with the sheriff and other officials, Trump said he was praying for the recovery of those injured, noting those in law enforcement particularly.
‘‘We grieve the loss of the law enforcement personnel who were killed in this vicious attack,’’ Trump said. ‘‘Many families tonight will go to bed in a world that is suddenly empty.’’
Piece by piece, investigators have put together a profile of Paddock, a retired accountant who made meticulous preparations for the moment when he smashed a plate-glass window in the 32nd floor of his hotel room and opened fire with a weapon, apparently modified to spew bullets with the split-second speed of an automatic rifle.
As he fired round after round during an 11-minute stretch from a suite at the Mandalay Bay, Paddock used multiple video cameras to keep an eye out for police storming his hotel room, according to Clark County Sheriff Joe Lombardo. Cameras were stashed in the suite’s peephole and in the hallway. But Lombardo said Wednesday that none of the cameras was recording.
In addition to guns found in the suite, investigators later found another 26 guns at two other properties in Nevada, as well as collections of ammunition and a chemical that can be used to make bombs.
Police have repeatedly said Paddock was the sole gunman, but they are still looking to see if he had any accomplices or help. Lombardo said, ‘‘You’ve got to make the assumption he had to have some help at some point,’’ given the amount of preparation and gear involved, but he said investigators had not identified any particular person.
Many of Paddock’s guns were purchased in recent years. Between October 2016 and Sept. 28, the day Paddock checked into the Mandalay Bay, Paddock bought 33 guns, the ‘‘majority of them rifles,’’ Jill Snyder, the special agent in charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives in San Francisco, said Wednesday in an interview with ‘‘CBS This Morning.’’
Paddock also had substantial ammunition in the room, with clips containing between 60 and 100 rounds, Snyder said.
