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 and comes just two days after the second 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.

Dr. Heather Melton, an orthopedic surgeon whose husband, Sonny, died shielding her from the gunfire, said she had mixed feelings about the settlement.

“There’s some good that comes from it, it will help give families closure and alleviates their ongoing medical costs,” she said. “But there’s no amount of money I would take to not get my husband back.”

The settlement creates the third-largest victims compensation fund in U.S. history, according to a claims administrator who has doled out money in major attacks and disasters. Kenneth Feinberg, who wasn’t involved in the Las Vegas deal, said he oversaw $7.1 billion in victim compensation after the Sept. 11, 2001, terrorist attacks and $6.5 billion following the 2010 BP oil spill in the Gulf of Mexico.

The amount of the settlement depends on the number of plaintiffs who take part, according to a statement from Las Vegas law firm Eglet Adams, which represents nearly 2,500 victims.

“Our goal has always been to resolve these matters so our community and the victims and their families can move forward in the healing process,” said Jim Murren, chairman and CEO of MGM Resorts.

Attorneys also will get some of the money, but wouldn’t say Thursday how much.

An independent administrator will be appointed by a court to dole out money from the settlement fund, attorneys and MGM said. They expect to wrap up the work by late next year, a timeline that Feinberg called “very realistic.”

MGM’s insurers will put a minimum of $735 million into the settlement fund. Depending on the number of victims who participate, the company will contribute more, up to $800 million, according to victims’ attorneys.

“Today’s agreement marks a milestone in the recovery process for the victims of the horrifying events of 1 October,” Robert Eglet, a lead plaintiffs’ counsel, said in the statement. “While nothing will be able to bring back the lives lost or undo the horrors so many suffered on that day, this settlement will provide fair compensation for thousands of victims and their families.”

A country music festival became a killing ground when a 64-year-old retired accountant and high-stakes video poker player fired out the windows of his hotel room into the crowd.

Stephen Paddock killed himself as authorities closed in, and they found 23 assault-style weapons in his room, many equipped with bump stocks that allow firearms to fire rapidly like machine guns.

Police and the FBI found that Paddock meticulously planned the attack and theorized that he may have sought notoriety. But they said they never determined a clear motive.

As legal claims piled up, MGM drew outrage when it filed lawsuits last year against more than 1,900 victims in a bid to avoid liability. The company argued that it didn’t owe anything to survivors or families of slain victims under a federal law enacted after 9/11.
