Criminal investigators who scanned computers belonging to Las Vegas shooter Stephen Paddock found that he was a member of several child pornography groups, and had been trading illegal pictures for some time.
According to a source within the US Attorney’s Office, the FBI had “known” that he was possibly involved in a child pornography ring and had been surveilling this group.
Police also released a 81-page preliminary investigative report on the shooting Friday, containing new photographs of Paddock’s hotel suite and online searches he conducted before the attack, such as for SWAT tactics and other potential public venue targets.
Paddock’s brother, Bruce, was arrested last year by Los Angeles police for possession of child pornography as part of a separate investigation that began months before the Vegas attack.
