Law enforcement speaking during a press conference say that there was a sizable police presence in the area of the concert, as is the case with all major events in the area. During his stay at the hotel, there were no signs law enforcement are aware of that would have indicated that Paddock had plans to commit this shooting.

The Clark County Sheriff said it is believed Paddock broke the hotel window of his 32nd floor room with  a "hammer-like" object before opening fire into the crowd at the festival. He is believed to have had at least 10 guns in the room. He was found dead in his room when officers entered.

Police continue to say that there is no known threat between Paddock and any foreign terror group. The Associated Press further backed up this statement, saying the FBI says there is no connection between the shooter any any international terror organization.

Suspected shooter Stephen Paddock was allegedly staying in the hotel room at Mandalay Bay since last Thursday. More information is coming out about the shooter. Paddock's brother spoke out this morning, saying he is “completely dumbfounded” by the shooting.

CBS News is reporting that ISIS is claiming responsibility for the mass shooting in Las Vegas. A pair of statements have been released by the terror group, saying the shooter converted to Islam several months ago and carried out the attack on behalf of ISIS. The group offers no proof of this claim and did not identify him by name. News organizations and government officials have not released any evidence of any connections between Paddock and ISIS at this time.

President Trump spoke in a press conference this morning, saying the FBI and other agencies are working with Las Vegas officials on the investigation.

She explained that Jason Aldean was "3 or 4 songs" into his set when a couple bangs went off doing one of his songs. She recalled turning to her fiancé and asking "What was that?" She initially thought the noises were fireworks before realizing that it was gunfire into the crowd.

At least 50 have been confirmed dead and at least 200 injured in what is now the deadliest mass shooting in U.S. history. Many of those in the crowd reported first hearing gunshots, thinking that it was pyrotechnics initially.

CNN reports the shooting was the act of a lone gunman that took aim at the festival from the 32nd floor of the Mandalay Bay Resort. The gunman, identified by Las Vegas Police as 64-year-old Stephen Paddock of Las Vegas, opened fire shortly after 10 pm Las Vegas time. Police say they believe was the sole actor in this shooting.

Paddock reportedly checked into Mandalay Bay as a guest. Once police determined where the shooting was coming from, they entered the room. Conflicting stories are out at this time. Some suggest police confronted and killed the gunman in the hotel room, while other reports suggest he took his own life before police entered the room. More on this as it becomes available.

Jason Aldean was onstage (video) when the shooting had begun. Other acts that were part of Sunday night's performances at the three day festival included Jake Owen, Luke Combs, and Kane Brown. Chris Young, who was also at the festival, hid in a trailer backstage as gunshots were fired by the gunman.

Many of the performers at the event took to social media to share updates on the situation, including Jason, who explained that he and his crew were safe and offer his thoughts and prayers for those in the crowd.
