Concertgoers took cover as the Las Vegas gunman fired into the crowd.
On October 1, a gunman opened fire from the 32nd floor of a hotel in Las Vegas, killing 58 people and injuring more than 500 more at a country-music concert. It was the deadliest mass shooting in modern US history.
The attack renewed America's ongoing debate over gun control, with particular interest in the use of bump stocks, which allowed the Vegas shooter to increase his rate of fire.
