Original Text

A gunman opened fire from a perch high up in the Mandalay Bay Resort and Casino in Las Vegas Sunday night, killing more than 50 people and leaving at least another 500 injured.

According to NBCNews.com, the shooting took place during the final night of the Route 91 Harvest Music Festival as headliner Jason Aldean and his band were playing. Police received the first call of a shooting at around 10 p.m. local time and were quickly on the scene.

The Las Vegas Police Department announced that they had identified the gunman as 64-year-old Stephen Paddock. Paddock was shooting concert goers from the 32nd floor of Mandalay Bay hotel until the police arrived, who then engaged him and he is now dead. Police also detained a companion of the shooter, Marilou Danley, who was located outside of the country. However, she is not believed to have been involved in the shooting and is no longer being sought as a "person of interest."

While tourists visiting the area hid in their hotel rooms to avoid the gunfire, authorities temporarily halted flights in and out of the McCarran International Airport in Las Vegas. Several people fleeing the scene breached an airport perimeter fence, but they were transported to the designated evacuation site and the fence line was secured.

As a result of the shooting, portions of the Las Vegas Strip have been temporarily closed and surrounding traffic has been diverted.

United States President Donald Trump, Nevada Governor Brian Sandoval and the Mandalay Bay Resort responded on Twitter to the shooting.

My warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting. God bless you!

In response, the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Federal Bureau of Investigation had responded to the shooting and were working together with local law enforcement efforts on the investigation, according to ABCNews.com.

While many initially thought the gunfire was fireworks, witnesses claim they quickly realized it was a shooting as people around them started to fall. As the shooting continued for “over a minute,” according to one witness, people started to flee from the scene, trampling others in the melee.

Several bystanders hopped into action immediately following the attack, making stretchers out of police barricades, plugging wounds with their hands and ripping off their own clothing to attempt to stop the bleeding of victims. At least one man described someone dying in their arms.
