U.S. President Donald Trump is going to Las Vegas on Wednesday, as investigators there continue to try to figure out why a gunman attacked a music festival from a hotel room high above, killing at least 58 people and then himself.

"We're going to see some of the folks that are recovering, some of the survivors," Trump said ahead of the trip. "We're also meeting with the police, with the sheriff, and we're going to spend quite a bit of time in Las Vegas."

The president also described the shooter as a "sick and demented person," and said that discussion about any new gun regulations is for "a later time."

Authorities have identified 64-year-old Stephen Paddock as the man who fired shots for between nine and 11 minutes from his 32nd-floor room at the Mandalay Bay Resort and Casino. In addition to those killed, more than 500 people were injured during the attack.

Clark County Sheriff Joe Lombardo told reporters Tuesday that he "absolutely" believes police will determine the shooter's motive and that he anticipated a "substantial amount of information" in the next few days.

"We are making progress but I don't have complete answers yet," he said.

One potential key to the investigation is Paddock's girlfriend, Marilou Danley, who Lombardo said was a person of interest in the case. She was in the Philippines at the time of the attack and flew back to the United States late Tuesday. She was met at Los Angeles International Airport by FBI agents.
