The family of a 13-year-old boy who died after two of his classmates attacked him at lunch will receive a $27 million settlement from a Southern California school district, according to the family’s attorneys, who said it is the largest school bullying settlement in U.S. history.

Juana and Felipe Salcedo, guardians of Diego Stolz, had sued the Moreno Valley Unified School District following his death in September 2019, claiming that the officials ignored several complaints they made between 2018 and 2019 to administrators at Landmark Middle School that Stolz was being bullied. They became his guardians after both of his parents died.

The case was settled on Wednesday.
