In Las Vegas, Nevada, MGM Resorts International has agreed to an $800 million settlement with more than 4,000 survivors of the 2017 massacre outside the Mandalay Bay casino. The settlement was announced after survivors joined friends and families of those killed at a commemoration Tuesday marking the second anniversary of the massacre. It was October 1, 2017, when a lone gunman named Stephen Paddock used semiautomatic rifles altered with bump stocks to open fire from the resort’s 32nd floor on a country music festival below, killing 58 people and wounding 851 others. It remains the worst mass shooting in modern U.S. history.
