The family of a New Jersey teenager who died by suicide after video of her being assaulted at her high school was posted online is suing the Board of Education and school officials, their attorneys said Monday.

The lawsuit, filed on behalf of Adriana Kuch’s family against the Central Regional Board of Education and others, alleges that officials were aware of “a culture of violence at Central Regional High School” and failed to protect her, the lawyers said.

Adriana took her own life after she was attacked by at least one other student in her high school last year and after video of the attack was posted online.

The assault and the video “led to her public humiliation and ultimate suicide,” the family lawyers said in a statement.
