https://mobile.nytimes.com/2017/10/25/u ... vegas.htmlParsing through the above article (linked earlier in this thread), the authors allude to more than one computer that may have been found in the room:
On Wednesday, information emerged that adds to the complexity of the case. Mr. Paddock apparently removed the hard drive from at least one computer found in his room at the Mandalay Bay Resort and Casino, according to a law enforcement official.
Indeed, just a bit further down in the article, there's this:
Suspects in mass shootings typically leave long trails of clues to justify their actions, writing manifestoes or posting on social media. But Mr. Paddock did not appear to do so, leaving investigators from the Federal Bureau of Investigation to pore over his computers and cellphones in the bureau’s lab in Quantico, Va., for weeks.
So the Feds have been
poring over numerous recovered media assets associated with Paddock for
weeks. This 'missing hard drive' issue isn't as dramatic as initially suspected if numerous other electronic assets have been retrieved and analyzed.
By now they'd have substantial information on web browsing history, recovered deleted files, etc.
Also: given the news of his brother's arrest, analysis of his brother's devices -- computers, mobile devices, etc -- have surely been initiated in earnest as well, which almost certainly includes analysis of communications/exchanges between the brothers.
Moreover, by now the Feds must have subpoenaed service providers (social media, web/mail hosting services associated with either/both brothers), indexed and searched through such records for noteworthy content.
(Indeed, It's possible analysis of 'shooter' Paddock's available electronic media may be what led to the brother's arrest, though this is speculative absent further information.)
The results of the above analysis is unlikely to ever make it into the public domain.
