WATCH: Las Vegas Investigators Reveal Disturbing Material Found On Stephen Paddock's Computer

Las Vegas Metropolitan Sheriff Joe Lombardo revealed on Friday that Stephen Paddock, the Las Vegas gunman, had a "disturbing" search history on his computer, which included child pornography.

Lombardo, in his first press conference since October, spoke about the new 81-page police report released on Friday, and added that the FBI is investigating an unidentified suspect.

“I realize it’s been three months since you have received an update on the 1 Oct. shooting,” Lombardo told reporters. “We have done a lot of work trying to piece together what happened.”

“This report won’t answer every question, or even the biggest question as to why he did what he did,” Lombardo continued. “We are all going to have to be patient and let the investigation run its course.”

Lombardo reiterated that it is the view of law enforcement that there was only one shooter, and that at this time there are no signs of radicalization.
