Officers were seen hunkering down behind a wall.
Another of the performers on the bill at the festival, country guitarist Caleb Keeter, issued a remarkable open letter after surviving the shooting.
People carry an injured person from the Route 91 Harvest country music festival in Las Vegas after gunfire erupted on Sunday night. Soon after, police said they believe that the gunman acted alone. Over 500 concert-goers were injured. "The chaos of not knowing where the shots were coming from, or who was shooting them". "I have a vest on". Stacks of ammunition magazines used in rifles can also be seen.
Investigators looking into Paddock also came across mention of Fenway Park, Boston police Lt. Detective Mike McCarthy said, though he provided no further details. It was not immediately clear what kinds of weapons were located. It has to come down to luggage at this point.
Nevertheless, his actions suggest that he had planned the attacks for at least a period of days.
He fired "off and on" for nine to 11 minutes, from the first call to police at 10:08 to 10:19 p.m. PT.
Jill Snyder of the San Francisco office of the Bureau of Alcohol, Tobacco, and Firearms said a total of 47 guns were confiscated from Paddock's hotel room and two of his homes.
"The band ran off stage and it was pandemonium", said Bessette. "That's a pretty substantial expense", he said.
But his music career almost didn't happen.
No evidence indicates terrorism, FBI special agent Aaron Rouse said, but the investigation is ongoing.
The elder Paddock remained on the lam for nearly a decade, living under an assumed name in Oregon. Sonny, a registered nurse, was bleeding from the mouth.
Heather Melton said she knew he probably was gone, but she wanted to hope. At least 31 people died at the hotel.
"I feel like out of respect for the victims, their families and our fans, it is the right thing to do", Aldean said in a statement.
Police had no prior knowledge of the gunman before the attack. "You've got to make the assumption he had to have some help at some point", he said.
"We had no other option", she said.
Police are still waiting to speak to Paddock's Australia girlfriend Marilou Danley who is in Tokyo.
Stephen Paddock, 64, shot himself before the police could get to his 32nd-storey suite in the Mandalay Bay hotel. "No religious affiliation, no political affiliation, he just hung out".
On Tuesday, Paddock's family sent condolences to the victims.
Country music singer Jason Aldean was performing when the gunshots began, according to witnesses' cell phone video. "Everyone was running, people were getting trampled". One of those has been upgraded from critical to stable condition.
"Every bed was full", Dr Coates said. "This wasn't a normal street weapon". "He was a guy who had money".
Corrine Lomas recalled the heroism of fellow concertgoers. "People were trying to save their friends".
But what motivated Paddock to kill dozens of strangers - and where he planned to strike next - remains a mystery.
The country star took to Instagram just hours after the shooting calling it "beyond horrific". Republican Senator James Lankford was among the officials to condemn the "despicable act of terror".
