Investigators Questioning Gunman's Girlfriend, and exploring shooter's attack plans.

Marilou Danley, the girlfriend of the Las Vegas gunman, was at the FBI's building in Los Angeles for questioning on Wednesday, according to a law enforcement official. Authorities are seeking her insight into what prompted a man with no evident criminal history to become a mass murderer, the New York Times reported.

The FBI bureau is trying to reconstruct the actions of the gunman, including finding and interviewing "everyone and anyone who crossed his path in recent weeks," Andrew G. McCabe, the deputy director of the F.B.I., said at a cybersecurity conference in Boston.

The killer, Stephen Paddock, "is an individual who was not on our radar or anyone's radar prior to the event," Mr. McCabe said in an interview with CNBC outside the conference. "So we really have a challenging bit of detective work to do here, to kind of put the pieces back together after the fact."

Meanwhile, investigators are exploring whether Las Vegas suspected shooter Stephen Paddock sought a hotel room overlooking another outdoor concert in Las Vegas in late September that featured Chance the Rapper and Lorde, sources told ABC News.

Paddock allegedly rented multiple condos at The Ogden complex in downtown Las Vegas, which overlooked the location of the Life is Beautiful Festival. A spokeswoman for The Ogden referred questions to Las Vegas police.

At a press conference on Tuesday, authorities were asked if there was any indication Paddock was planning an earlier attack. "No. I'm not prepared to speak about that, but that is part of our investigation," they replied. Bag checks at hotels unlikely to become the new normal, expert says

Live Entertainment Promoters Rethinking Security

Update, 3:00 p.m. E.T., 3 October 2017

Concert and music festival planners are taking a closer look at security protocols following the Las Vegas shooting�which is just the latest attack on a public entertainment venue. Last year�s terrorist attack on the Bataclan theater in Paris, where the Eagles of Death Metal were playing, and the attack earlier this year on the Ariana Grande concert in Manchester show that concerts are tantalizing targets due to their publicity and the large amount of people that flock to them.�

Damon Zumwalt, CEO of the company that provided about 200 security personnel for the Route 91 Harvest music festival,described to CNBC the moment he received the call from one of his managers about the shooting. Zumwalt�s company, Contemporary Services, works with law enforcement and runs active shooter drills but at a certain point there is nothing that can be done.

"We plan for practically everything, but you don't plan for something you can't control, like a guy off-property," Zumwalt said. "That's pretty devastating, and there's just no real reason for that kind of insanity."?

Following the trend of soft target attacks, many music venues have increased their security. However, experts note that securing an indoor venue is far easier than an outdoor festival�officials can more easily control who enters an indoor space and what they bring with them. Experts agree that there is very little that Route 91 Harvest could have done to prevent Sunday night�s tragedy.�

Going forward, festival organizers will have to be more mindful of event locations and the areas surrounding the festival�s footprint, according to Waco Hoover, CEO of XLIVE, which provides best practices for the industry. Event organizers will have to balance the need for an increased security presence�perhaps changes similar to what airports experienced following 9/11�while allowing the freedom to enjoy recreational activities that festivals foster.�

"If you look at the scenario, this (security) is not a festival issue,"Hoover told the Desert Sun. "This is not a Live Nation or Goldenvoice disclosing their security plans. They�re already working very, very closely with the city and the appropriate authorities to do those types of things. This is something which the producing entity has no control over.�

Twenty-Three firearms found in gunman's suite as investigation progresses

Update, 12:45 p.m. E.T., 3 October 2017

Officials are still investigating the events that led up to the horrific shooting in Las Vegas earlier this week, but did release information confirming they found 23 guns in the gunman's suite.

Las Vegas Metropolitan Police Department Sheriff Joseph Lombardo also told The New York Times that when Stephen Paddock's home was searched, they found 19 firearms, "some explosives, and several thousand rounds of ammo."

Some of the rifles found in Paddock's hotel room at Mandalay Bay may have been modified to make them fully automatic.�

"Automatic rifles, which fire multiple rounds with a squeeze of a trigger, are highly regulated, and on videos posted online by witnesses, the rapid-fire sound indicated that at least one weapon was fully automatic," according to the Times.

In a report by The Las Vegas Sun, officials said Paddock had two�"bump-stocks" that could have converted the firearms into?�fully automatic weapons.�

Officials are currently investigating whether those stocks were used to modify weapons Paddock ultimately used to carry out the massacre.

The shooting has also raised questions about hotel security and if there are measures that could have detected the ?firearms as they were brought into Mandalay Bay.

In an interview with the Times, Mac Segal, consultant at AS Solution, said hotel guests in the United States and Europe�place a premium on their privacy, so X-ray machines and explosive scanners are unlikely to appear at hotels anytime soon.�?ASIS condemns vegas shooting, releases resources on soft target security

In his first televised statement on the massacre, President Donald Trump called the Las Vegas shootings "an act of pure evil,"� and called upon Americans' "common humanity" to bring the nation together.
