Hey, everyone.

Elisa Donovan here, back with a new episode of Killer Thriller.

Today, we're going back to one of the most talked about true crime TV movies of the 90s, a film that still sparks conversation decades later.

You may know it as Death of a Cheerleader or maybe A Friend to Die For.

Same story, same tragedy.

And it is very real.

The film is based on the 1984 murder of Kirsten Costas, a popular high school student in Northern California who was stabbed to death by her classmate, Bernadette Proddy, in a crime fueled by jealousy, insecurity, and a desperate need to fit in.

And today's guest didn't play the victim.

She played the girl who killed her.

Kelly Martin starred as Angela Delvecchio, the fictionalized version of Bernadette, a role that required stepping into the mind of a teenage girl unraveling under social pressure and obsession.

Okay, so before we get to Kelly, I am going to bring in my producer who is an extraordinary resource surrounding this case because she grew up in the town.

I was 10.
