Original Story:

A mass shooting took place in Las Vegas Sunday night in which at least 50 people were killed and more than 400 people were injured and taken to area hospitals, according to Las Vegas police.

Stephen Craig Paddock is the 64-year-old white man who is the suspected shooter in the mass killing in Las Vegas Sunday night. Police believe Paddock acted alone.

The gunman opened fire on a country music concert from across the street at the Mandalay Bay Hotel and Casino.

Paddock was shooting from a room on the 32nd floor from the hotel. At least eight guns including long guns were found in the room, according to CNN. Paddock is believed to have killed himself before police stormed the room, according to Las Vegas Metropolitan Police Sheriff Joseph Lombardo.

It is being considered the deadliest mass shooting in U.S. history, surpassing the shooting in an Orlando, Florida nightclub last year in which 49 were killed.

There were approximately 22,000 concert goers at the Route 91 Harvest Festival when the shooting took place. Country singer Jason Aldean was performing when the shots rang out.

Las Vegas police were injured in the incident, and one off-duty officer was killed who was attending the concert. His name is being withheld until his family can be reached and notified. A woman, Marilou Danley had been sought in connection with the shooting, but police say they do not believe she was involved.

Police are still investigating the incident.
