This past spring, Harvard-Westlake, a prestigious prep school in Los Angeles, was thrust into crisis mode. Between March and June, three students died by suicide, setting off alarm bells within the school’s community.

The first death happened on March 2, when a 15-year-old sophomore girl took her own life. A member of Harvard-Westlake’s field-hockey team and an avid photographer, the student was honored at a school memorial later that month. The Chronicle, Harvard-Westlake’s student newspaper, dedicated the front page of its March issue to her, and a eulogy given by the student’s photography teacher was published in full.
