LAS VEGAS - A gunman in a high-rise hotel overlooking the Las Vegas Strip opened fire on a country music festival late Sunday, killing at least 59 people and injuring hundreds of others in the deadliest mass shooting in modern American history.

The gunman,     1     (identify) by police as Stephen Paddock, was later found dead by officers on the 32nd floor of the Mandalay Bay Resort and Casino, Sheriff Joseph Lombardo said during a news briefing Monday.

The carnage in Las Vegas surpassed the 49 people slain in June 2016 when a gunman   in   Orlando,     4     later said he was inspired by the Islamic State, opened fire inside a crowded nightclub.
