I saw some speculation on another sight that Paddock may have been involved with the Russia mob. Apparently, a “vor” named Razhden Shulaya was arrested in Las Vegas in June 2017.
I think that June was around the time that Paddock was prescribed the anti anxiety medication.
Also, if he became involved in money laundering for the Russian mob, his interest in buying a lot of guns might start to make sense. He apparently started his buying spree in October 2016.
This could also explain the FBI’s interest in the case, particularly if Paddock was an informer for them.
Aha, I knew it. It was the Russians /s
