LAS VEGAS — Two years after a shooter rained gunfire on country music fans from a high-rise Las Vegas hotel, MGM Resorts International reached a settlement that could pay up to $800 million to families of the 58 people who died and hundreds of others who were injured, attorneys announced Thursday.

It will resolve hundreds of lawsuits in multiple states that seek compensation for a range of physical and psychological injuries from the deadliest mass shooting in modern U.S. history, just two days after the anniversary of the Oct. 1, 2017, massacre.

Victims say the casino giant failed to protect 22,000 people at a concert venue it owns or stop the shooter from spending several days amassing an arsenal of assault-style weapons and ammunition in his suite at the Mandalay Bay resort.

The settlement creates the third-largest victims compensation fund in U.S. history.

The settlement fund will disburse at least $735 million, which MGM’s insurers will cover. If claims reach $800 million, MGM would pay $49 million to fill the gap above its insured amount of $751 million.
