“This lawsuit has put schools on notice to find ways to effectively deal with bullying and to enact real anti-bullying policies,” attorney Neil Gehlawat said in a statement.

Diego died nine days after a student sucker-punched him at lunch, attorneys Gehlawat and Dave Ring said in a news release.

The two teenagers involved, who were 14 at the time, entered the equivalent of guilty pleas in juvenile court to involuntary manslaughter and assault with force likely to cause great bodily injury, The Associated Press reported.

“The teacher informed the Assistant Principal that day; she claimed she would review the security footage to find the perpetrators, but she did not,” the family’s attorneys said.

The family alleged in the lawsuit that the district has “a long history” of failing to protect students who are being bullied.

The family will “forever be heartbroken” by Diego’s death but hopes his story “brings about change in school districts across the country,” their attorney said.
