LAS VEGAS (CNN) - Stephen Paddock, who sent bullets and terror down on thousands attending a Jason Aldean concert in Las Vegas, had an arsenal in his 32nd-floor hotel room and at his home 80 miles away, officials said.
In the hours after the retired accountant committed the deadliest mass shooting in modern US history -- killing 59 and wounding at least 527 -- authorities rolled out frightening new details, including the discovery of scopes on rifles at the resort and explosives at his home.
But what they couldn't explain is why the man who has never faced any notable criminal charges did it. There was no known motive late Monday.
