MGM Resorts International, the company which runs the Mandalay Bay Hotel, is suing more than 1,000 of the victims in what seems to be an attempt to avoid liability for the attack.
Stephen Paddock spent almost a week filling a room on the 32nd floor of the Mandalay Bay Hotel with a stockpile of weapons.
On October 1, he opened fire on the Route 91 music festival across the street from the hotel, killing 58 and injuring another 800.
MGM argue because there was a separate security company working at the festival, they should not be sued for the massacre.
The company is not seeking money, but say they want to prevent claimants from being able to file lawsuits against it for “deaths, injuries, and emotional distress resulting from Paddock’s attack”.
A lawyer representing a number of the victims has called the move “outrageous”.
Robert Eglet said: “I’ve never seen a more outrageous thing, where they sue the victims in an effort to find a judge they like.
“It’s just really sad that they would stoop to this level.”
Hundreds of people were killed or injured in last year’s attack after Paddock sprayed more than 1,100 rounds into the crowd in the space of ten minutes.
He had used a bump stock, which allowed his semi-automatic rifle to fire at a rate similar to that of a fully automatic weapon.
According to the filed lawsuit, the fact that a third party security company, Contemporary Services Corporation, was hired meant complainants should be suing them, rather than MGM.
The suit says: “The Safety Act expressly provides the federal courts with original and exclusive jurisdiction over ‘all actions for and any claims for loss [or] injury’ arising out of or relating to a mass attack where certified services were provided and where such claims may result in losses to the seller of those services.
“The Act and the associated regulations make clear that any such claim against the MGM Parties must be dismissed.”
Debra DeShong, spokesman for MGM Resorts, said: “The federal court is an appropriate venue for these cases and provides those affected with the opportunity for a timely resolution.
“Years of drawn-out litigation and hearings are not in the best interest of victims, the community and those still healing.”
