Las Vegas gunman methodically sought to 'thwart' investigation of massacre


The documents suggest Danley acted quickly after the shooting to hide her relationship with Paddock, the New York Post reported. Paddock killed 58 people and injured hundreds more before killing himself.

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.

The 315 pages of Federal Bureau of Investigation affidavits provide just a glimpse of what investigators found during initial searches of Paddock's auto and home after police found him dead late October 1 in a hotel room at the Mandalay Bay resort.

The agent says in the October 3 document that there was no evidence at that time of "criminal involvement" by Danley, but that investigators had not ruled out the possibility. 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".

Danley was "adamant that she had no prior inclination of Paddock's intentions to conduct the attack", says an Federal Bureau of Investigation agent's affidavit. Investigators scoured her social media accounts and emails - one of which he, Stephen Paddock, had access to. A court document said more than 1,000 rounds of ammunition also was found.

Danley was traveling in the Philippines when Paddock unleashed the bullet barrage from the 32nd floor of the Mandalay Bay resort.

Paddock bought numerous items on the Internet during the 12 months leading up to the attack.

He spent "significant time and expense prior to the attack purchasing and caching weapons" and other items, such as glass cutters and suitcases.

Police found 23 guns in Paddock's hotel room after the horrific shooting, as well as 19 firearms and thousands of rounds of ammunition found at his home. Also found were body armor, range finders and a homemade gas mask. The authorities have said he used the glass cutters so he could fire out of his hotel window at the people below, who were attending a country music concert. "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.

But investigators said the use of bump stocks on the night of the shooting allowed Paddock to fire rifles nearly as though they were automatic weapons.

At 2:46 a.m., her account was deleted, said the documents.

One instance where investigators identified two email account attached to him - and - an exchange began with "Try an ar before u buy".

"Investigators have been unable to figure out why Stephen Paddock would be exchanging messages related to weapons that were utilized in the attack between two of his email accounts".

Later that same day, the first account received a message stating: "we have a wide variety of optics and ammunition to try". An email in response suggested trying a bump stock on the rifle with a 100-round magazine.
