Police are looking for the motive behind the Las Vegas process

WASHINGTON (Reuters) - Investigators in the United States are identifying the motive for retired accountant Stephen Padock to carry out the worst shooting in recent American history at a music festival in Las Vegas.
The 64-year-old Stephen Padock collected a 42-piece arsenal of weapons at his home and hotel room where he opened fire on crowds attending the festival. The interval between the first emergency call and the police storming Paduc's room and finding it dead was an hour and 12 minutes.
The attack killed at least 59 people and injured 529 others during the shooting of the 22,000-person concert.
Badok committed suicide immediately after police stormed the hotel room where he was present, and found 10 rifles.

Trump reaction

President Donald Trump called on Americans to unite, describing the shooting as "absolute evil."
"The whole American people are sad and shocked and cry for their victims," Trump said.
The US president held a minute of silence with his wife Melania at the White House to mourn the victims.
"It's so painful, they came to enjoy their night, before Paduk opened fire on them from his balcony," said Jaysen Aladdin, the concert singer who was on the podium during the shooting at the concertgoers.
Investigators found no evidence to suggest that PADOK had links with any international terrorist organizations.
In his speech, Trump praised emergency services in Las Vegas, saying that "their high speed has saved many lives." He said he would visit Las Vegas on Wednesday.
