Stephen Paddock, the gunman who rained bullets on a Las Vegas festival on Sunday night, spent decades stockpiling weapons and ammunition, and “meticulously” planned the night he sprayed gunfire from his room on a crowd of concertgoers, says Clark County, Nv., Sheriff Joe Lombardo. Authorities still aren’t clear on why Paddock did what he did or who he was.

Describing the concert shooter as a lone wolf, Las Vegas Sheriff Joseph Lombado said, “I don’t know how it could have been prevented if we didn’t have any prior knowledge of this individual.” Law enforcement officials, politicians and hotel and concert managers offered the same sad lament: There’s very little that can be done.

Paddock took his own life as officers stormed his hotel room.
