Four Families Sue Meta, TikTok, Snapchat and YouTube Over Teenagers Who Died

Four families sued Meta, TikTok, Snapchat and YouTube on Thursday over the deaths of their children, filing in Delaware Superior Court in the latest and most pointed round of litigation to argue that the design of social platforms — not merely the content on them — is what killed the teenagers.

The suit was brought by the Social Media Victims Law Center on behalf of the families of Livi Castro, 13; Riv Kelleher, 14; Nathaniel Chambers, 17; and Dawson Holden, 18. The four died between July 2024 and September 2025, a span of roughly 14 months. The complaint alleges that each of them developed compulsive platform use, severe sleep deprivation, depression, anxiety and suicidal ideation over extended periods of use, and that the companies engineered the products to produce exactly that pattern of engagement.

"These platforms continue to kill kids, despite the platitudes of their executives," said Matthew Bergman, the center's founding attorney. The organization has filed dozens of similar cases over the past four years, and the theory underlying them has slowly gained traction with judges who have allowed product-liability and negligent-design claims to survive dismissal motions that the companies had expected to win on First Amendment and Section 230 grounds.

The financial pressure on the defendants is no longer hypothetical. Meta reported $2.4 billion in legal expenses in the second quarter of 2026 and faces multiple trials on parallel claims. The company, along with the other three defendants, has consistently maintained that it provides parental controls, age-appropriate default settings and crisis-resource interstitials, and that causal claims linking a specific product to a specific death cannot be substantiated.

Congress has produced no federal answer. The Kids Online Safety Act, which would impose a duty of care on platforms toward minor users, has stalled repeatedly since 2023 amid disputes over whether its enforcement provisions could be used to suppress lawful speech. In the vacuum, the fight has moved almost entirely to state courts and state attorneys general, with dozens of states running their own suits against Meta over youth mental health.

Delaware is a deliberate venue choice: most large American technology companies are incorporated there, which gives the state's courts jurisdiction over corporate-governance and design-decision questions that plaintiffs argue sit at the center of the case. The families are seeking damages and injunctive relief that would force changes to recommendation algorithms, notification systems and the infinite-scroll mechanics that the complaint describes as the operative harm.
