BREAKING: At Least 50 Dead Following Mass Shooting in Las Vegas

 The death toll has risen to 50 and this is the deadliest mass shooting in United States history. 

The suspect has been identified as Stephen Paddock of Las Vegas.

Danley has been located.

The Las Vegas Police Department believes that the only suspect in the shooting is dead, and they are seeking to locate the "companion" of the shooter, a woman identified as Mari Lou Danley. The suspect has been identified only as a "local resident" and police are not yet releasing his name. Danley is the roommate of the suspect. 

There are "well in the excess of 100 injured," and at least 20 people dead, the Las Vegas Sheriff Joe Lombardo said at a press conference. Exact numbers are not yet available.

Lombardo clarified that they do not believe there was multiple shooters and reiterated that the only suspect is dead.

The shooting took place from the 32nd floor of the Mandalay Bay hotel. 

Anyone with video is being urged to come forward. 

Singer Jason Aldean posted on his Instagram account that the night has been "beyond horrific" and said that he was praying for the victims of the attack. He confirmed that he and his crew are all safe.

McCarran Airport in Las Vegas has partially reopened. 

Country singer Jason Aldean, who was performing during the attack, is safe, along with his team. 

The shooting may have occurred from a hotel room, but this is not confirmed.

 The suspect was found dead in a hotel room on one of the upper floors of the hotel. 

 Police say that they are not looking for any additional shooters. A press briefing at 12:45 AM PDT will have additional information. 

Police have again confirmed that one suspect is "down," but did not confirm the presence of an additional suspect. People are being urged to avoid the Las Vegas Strip. 

ABC interviewed one of the people at the concert, who said that initially people thought the gunshots were fireworks.
