Authorities say Stephen Paddock, a 64-year-old resident of Las Vegas, is the shooter who killed 50 people in the mass shooting at the Route 91 Festival late Sunday night on the historic Vegas Strip — but have not revealed a motive or whether the alleged shooter was following any "belief system."
He is from Mesquite, Nevada, which is located around 80 miles northeast of Las Vegas, NBC News reported. The Las Vegas Metropolitan Police Department was not immediately available for comment and Clark Country Sheriff Joseph Lombardo did not reveal any further details about Paddock.
Police engaged Paddock and killed him on the 32nd floor of the Mandalay Bay Hotel and Casino across the street from the festival. The suspect is believed to have checked in as a hotel guest, the Associated Press reported.
Police said they believe the shooting was a "lone wolf" attack, one not linked to a militant group and not carried out by multiple shooters.
It is unclear if they have also found the suspect's 62-year-old Asian female roommate, whom authorities identified as Marilou Danley and described as an "associate" who stands at 4 foot 11 inches tall and weighs around 111 pounds.
Her Facebook page, now down, read that she is a "proud mom and grandma who lives life to the fullest."
Police also said they are searching for a 2017 Hyundai Tuscon, with the number plate NV 114B40.
"We have no idea what his belief system was," Las Vegas Sheriff Joe Lombardo said. "Right now, we believe he was the sole aggressor and the scene is static."
The gunman launched the assault during a performance by country music star Jason Aldean, who was being watched by a crowd of around 50,000. The bullets rained down in three long bursts, a witness video revealed.
The assault injured more than 200 people. At least two of the victims were off-duty police officers.
The death toll of 50 means that more people have died than in the Orlando shooting attack in June 2016 by a sympathizer of the Islamic State militant group at a LGBT nightclub that left 49 dead.
Police said he was a local resident and a search result shows that a man by the name Stephen Paddock lived with Danley at a residence in Mesquite, Nevada.
An eyewitness, Quinn Mell-Cobb, a 24-year-old Sales Representative for Warrior Hockey, told Newsweek how gunshots sounded like they were coming from "everywhere" and initially sounded like "firecrackers." The slow realization that they were gunshots resulted in mass panic and shrieks from the crowd as the gunfire continued.
