The family of a high school senior at Waterbury Arts Magnet School who committed suicide after years of alleged taunting and abuse from fellow students has sued the school for at least $1 million.

The lawsuit, filed Wednesday afternoon in Waterbury Superior Court, alleges 17-year-old Alison Ternig was the victim of bullying from peers from September 2014 until her death last June. The incidents, the lawsuit claims, included her constantly being called fat and ugly to crude comments about sex.

The last straw, the lawsuit alleges, was on June 5, the day before Ternig killed herself. On that day, the suit maintains, Ternig accidentally got on the wrong bus following a trip to Six Flags New England when students on the bus verbally attacked her, yelling “get your f—– fat ass off our bus, you don't belong here.”
