A U.S. judge in Nevada unsealed the documents showing some of what federal agents learned about in the week after the Las Vegas shooting.
According to the documents, Stephen Paddock’s girlfriend told investigators they would probably find her fingerprints on bullets because she helped him load ammunition magazines.
Marilou Danley may not have been present when Paddock unleashed a furious barrage of bullets down on a crowd of 20,000 at a Las Vegas country music festival, murdering 58 people and wounding more than 500 others, but her links to his life seemed to be everywhere.
Prosecutors also show that agents sought the email, Facebook and Instagram accounts of Paddock’s girlfriend, Marilou Danley. They revealed an exchange about a money wire transfer. Danley returned from a trip to the Philippines days after the shooting, but wasn’t arrested when she arrived in the United States.
Inside his hotel room, investigators found two unlocked cell phones. “Neither contained significant information that allowed investigators to determine the full scope of Stephen Paddock’s planning and preparation for the attack,” the documents said.
A third cell phone, which was locked, could not be accessed, according to the Los Angeles Times.
Investigators said he used anonymous communications devices, including a prepaid cellphone, to cover his tracks and employed a “level of sophistication which is commonly found in mass casualty events.”
Also unveiled on Friday: Emails Paddock had exchanged about buying rifles and bump stocks months before he carried out the mass shooting.
Paddock’s email address and the Gmail address had similar names, leading investigators to suspect that he may have been emailing himself, although they couldn’t figure out why.
FBI agents reportedly knew that Paddock had left behind big caches of guns, ammunition and explosives when they sought warrants to search his properties and online accounts, according to the documents.
Las Vegas Police Officer Aden Ocampo Gomez and FBI spokeswoman Sandra Breault said Friday that they had no update about Paddock’s motive.
Both called it an ongoing investigation.
