The families of four teenagers who died by suicide have filed a lawsuit against Meta, TikTok, Snapchat, and YouTube, alleging that prolonged use of these platforms contributed to the deaths. The complaint, filed Thursday in the Superior Court of Delaware, contends that the social media companies engaged in practices that led to “years of escalating harms” resulting in addiction, severe sleep deprivation, depression, anxiety, and suicidal ideation among the teens.

The suit was brought on behalf of families from Texas, North Carolina, Minnesota, and Tennessee, whose children died between July 2024 and September 2025. The plaintiffs include Livi Castro, age 13; Riv Kelleher, 14; Nathaniel Chambers, 17; and Dawson Holden, 18. The Social Media Victims Law Center is representing the families, with its founding attorney, Matthew Bergman, emphasizing the ongoing risk posed by these platforms despite prior similar lawsuits. “These platforms continue to kill kids, despite the platitudes of their executives,” Bergman said.

The complaint alleges that the social media companies were aware of the harms their products were causing young users but failed to take sufficient action. It accuses the platforms of fostering addictive behaviors and exposing teenagers to content and functionalities that exacerbated their mental health struggles.

A spokesperson for Google, the parent company of YouTube, responded to the lawsuit by stating that the company is committed to providing a safer and healthier experience for young users. The statement noted that Google collaborates with mental health and parenting experts to develop age-appropriate features and robust parental controls. “We send our deepest sympathies to the families and are reviewing the claims in this lawsuit,” the spokesperson added.

Representatives for Meta, TikTok, and Snap did not immediately provide comments on the legal action.

This filing is part of a broader wave of litigation against major social media firms, focusing on the platforms’ effects on youth mental health and well-being. The cases spotlight growing concerns about the role these companies play in contributing to addiction and psychological distress among teenagers.
