A gunman carried out the deadliest mass shooting in US history by opening fire at a Las Vegas outdoor music concert — killing at least 50 people and wounding more than 200 before being fatally shot, officials said.Stephen Paddock, 64, of Mesquite, Nev., unleashed a withering hail of bullets from an automatic weapon from the 32nd floor of the Mandalay Bay hotel as about 40,000 people were enjoying the music.Described as a “lone wolf” by Clark County Sheriff Joseph Lombardo, Paddock had a criminal past and was known to local law enforcement, NBC News reported.He had no known connection to terrorism and police have not called the shooting a terrorist attack, according to Lombardo.Modal TriggerUndated image of Stephen Paddock.Facebook“We have no idea what his belief system was,” Lombardo said. “Right now, we believe he was the sole aggressor and the scene is static.”He added that “numerous firearms” had been located in the room he had occupied at his Mandalay Bay room, which a SWAT team broke into with a controlled explosion.The attack came during the last performances on the final night of the three-day Route 91 country music festival on a 15-acre lot on Las Vegas Boulevard across from Mandalay Bay.Authorities said they have located 62-year-old Marilou Danley, who was wanted as a person of interest in the massacre. She had been sitting in Paddock’s car before the attack, Lombardo said.He described her as an “associate.”Police also found two vehicles with Nevada license plates, a Hyundai Tucson and a Chrysler Pacifica Touring, that they had been looking for after the rampage, the Las Vegas Review-Journal reported.Two off-duty police officers attending the concert were among the dead victims, Lombardo said. Two on-duty Las Vegas cops were wounded, one critically, he said.President Trump tweeted his “warmest condolences and sympathies to the victims and families of the terrible Las Vegas shooting.
