The last thing that anyone wants to wake up to is heartbreaking news. However, that's exactly what we're getting now that a mass Las Vegas shooting has left over 50 people dead, and at least 400 injured.

According to CNN, A gunman on the 32nd floor of the Mandalay Bay Hotel and Casino unleashed a shower of bullets onto the Route 91 country music festival Sunday night. The shooter has been identified as 64-year-old Stephen Paddock, a resident of Mesquite, Nevada. The gunman has since been killed by police after his hotel room was raided. Police believe that he was a "lone wolf" and no other shooters were involved. 

The concert festival was taking place in an outdoor area across from the Mandalay Bay and Luxor casinos on the famed Las Vegas Strip. Several videos have been shared in which you can hear gunshots going off, and people running for their lives. 

The story is developing, and not much is known about the shooter or his motives. A full list of identified victims has yet to be released either. With no understanding of his motives, police are not calling this an act of terrorism at this time. Sheriff Joe Lombardo, when asked by a reporter if it was an “act of terrorism,” said “no, not at this point. We believe it was a local individual. He resides here locally." 

“We believe it’s a solo actor. A lone wolf,” Lombardo also said. “We are comfortable that the primary aggressor in this event has expired or passed away and is no longer a threat.”

Police are also searching for a companion and roommate of the shooter named Marilou Danley. While police are not sure if she played a role in the shooting,  a woman who was at the concert told a local news station that a “lady pushed her way forward in the concert venue. And she started messing with another lady and told us that we are all going to die tonight...It was about 45 minutes the shots were actually fired. But then she was escorted out by security.”

Police have yet to figure out and confirm if the two incidents are related. 

We do know that this now takes the top spot of deadliest shootings in modern U.S. history. Prior to now, 49 people were killed when a gunman opened fire at the Pulse nightclub in Orlando in June 2016.

According to ABC News, police have asked anyone with cell phone footage or other videos from the shooting to provide them to investigators.

“Anybody that may have cell phone video or any type of video associated with this event that would be a benefit to the investigation, please respond to the Las Vegas Metropolitan Police Department headquarters at 400 South Martin Luther King and we will take custody of that video. Please bring that down to the headquarters.”

Prayers go out to the family of the victims of this terrible act of violence. As the story is developing, updates are sure to come.
