Hundreds of pages of court documents unsealed Friday in the case of Las Vegas gunman Stephen Paddock offer a blueprint of investigators' pursuits in determining how and why the reclusive high-stakes gambler carried out the deadliest shooting in modern US history.
Bump stocks believed to be used in the massacre were found in the 32nd-floor hotel room from where Stephen Paddock fired down on a crowd gathered on a Sunday night for the finale of a country music festival held on the Las Vegas Strip.
Newly unsealed search warrants show that investigators trying to piece together the details of the deadly mass shooting in Las Vegas have not yet found a motive.
The documents also showed that Paddock's girlfriend, Marilou Danley, told investigators before they searched a house that the two shared that they might find her fingerprints on ammunition "because she occasionally participated in loading magazines", the Las Vegas Review-Journal reported.
Stephen Paddock's emails were disclosed in affidavits unsealed Friday after several media organizations, including The Associated Press, fought for their release.
An FBI agent tells a judge in warrant documents made public Friday that Marilou Danley wasn't arrested when she returned to the US from the Philippines days after the October 1 shooting, and that she was cooperating with investigators.
If there was a second person involved in the communications, an Federal Bureau of Investigation agent wrote, "investigators need to determine who was communicating with him about weapons that were used in the attack". "With the shooter dead and no indication that co-conspirators were involved, authorities have no legitimate reason to lock down records related to their investigations".
NFL to consider Cam Newton knee injury during concussion protocol investigation
The Panthers quarterback went to the ground as he left the field but quickly returned to the game after missing only one play. Newton said after the game Sunday that "precautionary concussion protocol things" happened, but "it wasn't my head.
Warrants also showed that investigators found an email address identified by investigators as Paddock's where he received a message from an account identified as CentralPark4804@gmail.com that read, "for a thrill try out bumpfire ar's with 100 round magazine".
In the days after the shootings, authorities called Danley a "person of interest".
Investigators have said that Paddock meticulously planned his attack and intentionally concealed his actions. The FBI special agent who signed the affidavit argued that since only that phone was locked, any information related to a criminal conspiracy would be found on it. But it notes that while investigators had not found "any conclusive evidence" that she helped Paddock, knew about his plans in advance or lied to law enforcement, that remained "the subject of intensive review".
Clark County Sheriff Joe Lombardo later said that October 2 search found 19 guns and several pounds of potentially explosive materials.
Authorities wrote in one filing that they believe Paddock was controlling two email accounts that were exchanging messages discussing weapons used in the attack.
Police and the Federal Bureau of Investigation say Paddock acted alone and killed himself.
