The Las Vegas shooter's motive remains unknown, but his recent travel history may provide investigators with some clues as they piece together a profile of the killer.
What does his travel show?
In addition to being an avid gambler and gun enthusiast, 64-year-old Stephen Paddock loved to travel and has been on 20 different cruises, investigators say, including to areas of Europe and the Middle East.
The cruises included stops at ports in Spain, Italy, Greece, Jordan and the United Arab Emirates, according to information provided by a law enforcement source who asked not to be identified because the source was not authorized to share information about the investigation. Paddock's girlfriend, Marilou Danley, accompanied him on nine of the cruises.
CNN noted the source was unable to provide "cruise line involved, the type of cruises, when they occurred or the couple's reason for travel."
Why does it matter?
Just hours after the massacre, the Islamic State took responsibility for the shooting, which took the lives of nearly five dozen people and injured more than 500 others. The terrorist group claimed that Paddock had recently converted to Islam and pledged allegiance to the group's cause.
In a follow-up claim in the group's newsletter, they claimed Paddock had converted to Islam about six month prior to carrying out the massacre, gave information about the shooting and said Paddock's converted Islamic name was "Abu Abdul Barr al-Amriki."

However, investigators don't believe foreign terrorism was the motive or that the Islamic State was anyway involved. Reporters who are experts in the Islamic State have been weary to discount the group's claim for credit.
