A day after 59 people were killed and 527 others were wounded at a shooting at a Las Vegas concert, police said they had recovered an arsenal of at least 42 weapons stashed in the gunman's car, house and hotel room, but had still had not discovered a motive for one of the worst mass shootings in U.S. history.
Paddock owned a single-family home in Sun City Mesquite, a retirement community along the Nevada-Arizona border, Mesquite Police Chief Troy Tanner said.
Local media said he had also previously lived in Reno, Nevada, California and Florida. She was initially considered a person of interest in the case, but it was later found that she was out of country at the time of the incident and her involvement in it seemed unlikely.
When retiree Stephen Paddock checked into his 32nd-floor hotel suite at the Mandalay Bay Resort and Casino last Thursday, nothing appeared unusual.
Among his weapons, a law enforcement official said, were AR-15-style rifles, a civilian variant of a standard service rifle used by the American military for more than a half-century.
Trump praised first responders, including the Las Vegas Metropolitan Police Department, "for their courageous efforts".
Police found in the gunman's car several kilos of ammonium nitrate, a substance used in the manufacture of explosives. Moreover, the report says that in a statement ISIS referred to Paddock by the nom de guerre Abu Abd al-Barr al-Amriki.
Las Vegas is still reeling after tragedy on the Strip. All times are Pacific.
Fifty-nine were killed and over 500 injured when Paddock opened fire onto the music concert.
Witnesses described chaos as people ran for their lives as bullets rained down at the outdoor show, next to the city's iconic Strip.
Once Paddock had purchased the weapons, there was the matter of transporting them to his hotel room.
The presence of other hotel guests in the rooms surrounding Paddock's meant that police couldn't return fire from the ground, he explained.
"We can't understand what happened", a distraught Eric Paddock, Stephen's brother, told reporters outside his home in Orlando, Florida.
In footage of the shooting at the Route 91 Harvest Festival, multiple rapid gunshots could be heard as people tried to flee the scene. It then started up again before another round of pops sent performers ducking for cover and fleeing the stage, while panicked fans also rushed for the exits.
"The world has changed.
In the days ahead, we will grieve as a nation, we will honour the memory of those lost as a nation and we will come together united as one nation, under God, indivisible", she added.
