BUFFALO, N.Y. —  Almost a year since the massacre at a Tops supermarket in Buffalo, the emotion is still raw.

"I wanted to say so much to my father before my father died and that got taken away from me," Leandra Elliott, the daughter of shooting victim Andre Mackniel, said.

"I don't even know how we’re here in this country doing the same stuff we’re doing. It's absolutely disgusting,” said Adrian Massey, the niece of victim Katherine Massey.

Attorneys for these families whose loved ones were murdered by a white supremacist say people and companies need to be held accountable.

"It's the money. It's always the money,” said Barbara Massey-Mapps, Katherine Massey's sister. “So what you do? You take some of their money.”

On Friday they filed a wide-ranging lawsuit in state Supreme Court naming major social media platforms, a gun parts manufacturer, a body armor manufacturer, a gun store and the shooter's parents as defendants. Attorney John Elmore is among the lawyers representing them.

"We prepared a summons complaint that would tell the whole story,” said Elmore. “We believe that all the defendants are proportionately responsible for what happened.”

The headliner though are the social media platforms and their algorithms, which attorneys assert by design radicalized the shooter and provided him with the resources necessary to carry out the heinous act.

The team brought in national expert Matthew Bergman from the Social Media Victims Law Center to help with the case.

Bergman said it's the first-of-its-kind and will likely draw major money and legal teams from the huge companies like Facebook, Reddit and Twitch.

"By focusing not on the content but on the design, we are confident that we're going to be able to hold them accountable before a jury of their peers and this community is going to be able to say, finally, enough is enough," he said.

Elmore said they are not able to ask for a specific sum of money in the lawsuit and it will be decided by a jury if successful. The attorney said he believes it should be significant though.

"Knowing that these corporations are making billions of dollars, I would think that a jury, if they want to punish the company or deter that conduct, would issue a substantial award," Elmore said.
