More than 20 people were killed and more than 100 injured in a shooting on the Las Vegas Strip Sunday night police said.

Las Vegas Metropolitan Police Sheriff Joseph Lombardo told reporters that police responded after reports of shots being fired from the Mandalay Bay towards the Route 91 Harvest festival.
"We determined there was a shooter on the 32nd floor of the Mandalay Bay," Lombardo said. Officers engaged the suspect, whom Lombardo described as a "local resident." He said that the shooter is dead and that police believe that there are no other shooters. "Right now we believe it's a sole actor, a lone-wolf-type actor," said Lombardo.
Police have identified the gunman but will not be naming him at this time, Lombardo said.
