The movie Death of a Cheerleader was based on a real case.
Angela Delvecchio's character was based on Bernadette Protti, and her 1984 murder victim Stacy Lockwood was based on Kirsten Costas.
The Angela Delvecchio character played by Kellie Martin is actually the opposite of Bernadette Protti – who was older, taller and blonde - while Kirsten Costas, played by Tori Spelling – was only 15, shorter and dark-haired. Nothing like the movie.

The Kirsten Costas story that was the basis for Death Of A Cheerleader was published in Rolling Stone in 1985 and was also covered by all the media.
Bernadette Protti basically killed Kirsten Costas over an imagined slight and fear of being exposed as a scheming, socially inept wannabe.

The story is so sad.
