However, new questions were raised after a US judge in Nevada unsealed the documents revealing some of what federal agents had learned about shooter Stephen Paddock in the week after the Las Vegas attack.
The FBI search warrants shed new light on the degree to which the gunman, who killed 58 people and wounded more than 500 others when he opened fire on a crowd from a hotel room in October, planned the attack and prepared for the aftermath.
An hour before Las Vegas cops released Stephen Paddock's name, Danley deleted her Facebook account, according to newly released documents about the October 1 mass murder of 58 people attending an outdoor country music concert on the Strip.
Stephen Paddock's emails were disclosed in affidavits unsealed Friday after several media organizations, including The Associated Press, fought for their release.
The documents also showed that Paddock's girlfriend, Marilou Danley, told investigators before they searched a house the two shared that they might find her fingerprints on ammunition "because she occasionally participated in loading magazines", the Las Vegas Review-Journal reported.
Authorities released Paddock's name about an hour after Danley deleted her account.
The documents detail how he attempted to thwart authorities.
Stephen Paddock, 64, attacked the Route 91 Harvest music festival in a mass shooting in Las Vegas, killing 58 people.
Officials with the Las Vegas Metropolitan Police Department did not return a request for comment. Agents said their initial search found "a large quantity of ammunition and multiple firearms" on the property. By 5 a.m., she had been located and identified as "a person of interest" in the shooting.
Netanyahu arrives in India, greeted on tarmac by PM Modi
Netanyahu's visit comes days after India voted against Israel at the United Nations on the Jerusalem issue. Before leaving for his six-day trip to India, Netanyahu promised to "sign very many agreements".
On Friday, U.S. District Judge Jennifer Dorsey said she saw no reason to keep the warrants sealed, especially since lawyers with the federal government did not oppose the unsealing, with some minor redactions.
The warrants released Friday also produced a puzzling email exchange that Paddock appeared to have with himself.
Paddock also set up cameras in the hallway outside the room.
Then Paddock sent an email to centralpark4804gmail.com that read: "for a thrill try out bumpfire ar's with 100 round magazine". Receiving a search warrant for that account "will lead investigators to determine the full scope of Stephen Paddock's plan", an F.B.I agent wrote to the judge.
Within Paddock's email accounts, investigators had identified a July 6 thread that appears to contain messages sent by Paddock to himself.
Investigators said the exchange could be "related to the eventual attack that occurred at the Mandalay Bay in Las Vegas".
Inside his hotel room, investigators found two unlocked cell phones.
In their requests for data from Instagram, investigators said they were seeking "evidence showing the possession, use, purchase or sale of firearms, firearms accessories, ammunition or explosives by Paddock". "Conversely, if the Target Account was not controlled by Stephen Paddock, investigators need to determine who was communicating with him about weapons that were used in the attack", according to a warrant.
