The suit (PDF) was filed October 6 in Clark County, Nevada, court, on behalf of concertgoers who suffered emotional distress during the October 1 shooting, report Courthouse News Service, Bloomberg News, Reuters, the Las Vegas Review-Journal and a press release.
The devices were originally meant to help people with disabilities who have arm mobility issues fire a semi-automatic long gun.
The complaint also names other manufacturers and retailers of bump stocks. The Nevada plaintiffs are seeking unspecified punitive damages.
The proposed class action lawsuit, filed in state court in Clark County, Nevada, over the weekend and announced on Tuesday, accuses Slide Fire Solutions and other unnamed manufacturers of negligence leading to the infliction of emotional distress on thousands of people who witnessed or were injured in the October 1 shooting at a Las Vegas music festival.
Representing the Plaintiffs are Robert Eglet, Robert Adams, Aaron Ford, and Erica Entsminger of the Eglet Prince law firm, and Jonathan Lowy, of the Brady Center to Prevent Gun Violence.
"The people who attended the concert have suffered so much already", Brady co-presidents Kristin Brown and Avery Gardiner said in a statement. They claim Slide Fire markets the product under the guise that it helps gun owners who suffer from a lack of mobility in their hands. Some top Republicans in Congress and leaders of the National Rifle Association have said they would support additional regulation for the devices. As a result, the shooter can fire nearly continuously.
Gunman Stephen Paddock, who killed himself after carrying out the attack, had a dozen bump stocks in his hotel room at the time his body was found by police.
The lawsuit said the company acted with fraud, oppression and malice toward plaintiffs and showed an intention and willingness to injure people. Slide Fire marketed its bump stock as a military-grade accessory for civilians, and sold for $100 to $400, depending on the model.
Slide Fire's website on Tuesday noted that it had "temporarily suspended new orders".
The members of the class action suit are seeking equitable relief in the form of a court supervised program for psychological monitoring for all the Class Members at the expense of the Defendants.
