Investigators still have not found a motive for the Las Vegas massacre, an F.B.I. official said Wednesday, but they hope that the gunman’s girlfriend, who officials said had returned to the United States from overseas, can provide some insight into what prompted a man with no evident criminal history to become a mass murderer.
The bureau is trying to reconstruct the actions of the gunman, including finding and interviewing “everyone and anyone who crossed his path in recent weeks,” Andrew G. McCabe, the deputy director of the F.B.I., said at a cybersecurity conference in Boston.
Interviewed outside the conference by CNBC, Mr. McCabe said: “We don’t have any immediately accessible thumbprints that would indicate the shooter’s ideology or motivation or, really, what compelled him to get there.”
The killer, Stephen Paddock, “is an individual who was not on our radar or anyone’s radar prior to the event,” he said. “So we really have a challenging bit of detective work to do here, to kind of put the pieces back together after the fact.”
• Marilou Danley, Mr. Paddock’s girlfriend, returned to the country late Tuesday night, landing at Los Angeles International Airport on a flight from the Philippines, officials said. Ms. Danley, who has been described by the sheriff of the Las Vegas police as a “person of interest” in the case, was met by F.B.I. agents, according to a law enforcement official.
• Mr. Paddock, a high-stakes gambler, wired thousands of dollars to the Philippines just days before the shooting, a federal official said. The authorities would not confirm to whom the transactions were intended.
• The police on Tuesday revised the number of victims killed on Sunday to 58. All but three of the people have been identified. These are some of their stories.
• President Trump was visiting Las Vegas on Wednesday. “We’re going to pay our respects and to see the police who have done really a fantastic job in a very short time,” he said as he left the White House on Wednesday with the first lady, Melania Trump.
The gunman’s girlfriend has returned to the U.S.
Ms. Danley boarded a flight from Manila to Los Angeles on Tuesday, according to Antonette Mangrobang, a spokeswoman for the Philippine Immigration Bureau.
The authorities, who met Ms. Danley at the Los Angeles airport, have called her a “person of interest” in the shooting investigation, which does not necessarily mean that she is suspected of committing a crime. She was out of the country when the shooting occurred.
More than three hours after her flight came in from Manila, an airport police officer confirmed that she had been taken out of the terminal through a side exit.
In an interview with ABC News, Reynaldo Bustos, Ms. Danley’s brother, said he had spoken with her after the shooting. He said she told him not to panic and that she had a “clean conscience.”
Ms. Danley met Mr. Paddock when she was working at a Nevada casino and he was a high-limit player, casino employees said. She worked at the Atlantis Casino Resort Spa in Reno from 2010 to 2013, according to her LinkedIn account.
John Weinreich, an executive casino host at the Atlantis Casino Resort Spa at the time, said he believed that Ms. Danley frequently attended to Mr. Paddock, serving him food and pointing out which machines might be ripe for a payout, eventually becoming his regular host.

Las Vegas police officers took cover and directed concertgoers to safety as gunshots rang out on Sunday, newly released body camera footage shows.
“Hey, you guys, get down,” one officer shouted at bystanders between volleys of gunfire. “Go that way. Get out of here. There are gunshots coming from over there. Go that way.”
But some people did not believe they were under attack and rebuffed orders to evacuate. “That’s fireworks,” one bystander shouted at officers. Another yelled expletives when told to take cover.
As sirens blared and gunfire crackled, the video showed, officers strained to find the source of the shots.
“Hey, they’re shooting right at us, guys,” one officer said as he and his colleagues crouched behind a wall with their weapons drawn. “Everybody stay down, stay down.
“North of the Mandalay Bay, it’s coming out of a window,” another officer says.
The three-minute video released by the police on Tuesday was a compilation of footage from the cameras of several officers at the scene.
“There’s multiple people shot up there,” someone says in one clip.
“We see muzzle blasts from the Mandalay Bay,” someone, apparently an officer, said in another clip.
The police have also confirmed the authenticity of leaked photographs of the deceased gunman with a revolver by his side and of his hotel suite, showing ammunition and rifles.
