Episode Overview

This episode of "Killer Thriller" dives deep into the real-life tragedy that inspired the 1994 TV movie Death of a Cheerleader (also known as A Friend to Die For). The film, starring Tori Spelling and Kellie Martin, was based on the 1984 murder of Kirsten Costas by her classmate Bernadette Protti in a suburb of San Francisco, California. Host Elisa Donovan is joined by actress Kellie Martin, who played the fictionalized version of the killer, to explore the complexities of the case, the making of the film, and its lasting cultural impact.

Key Discussion Points & Insights

Recollections from the Local Community

• Host and Producer's Personal Connection:

  • Elisa’s producer grew up in the same town as the murder occurred and shares vivid memories—her parents knew the family, and she recalls the funeral and neighborhood searches for the “green Pinto” associated with the killer.

    “It was so, like, what. What's the memory of it? ... I can remember my parents going to the funeral. I can remember sitting in my living room...” — Producer/Host (06:31)

  • The producer reflects on the enduring emotional aftermath in the town, expressing discomfort discussing the case because of its lingering pain among those involved.

• Social Dynamics in 1980s High School:

  • That era’s culture, including girl cliques, local "sororities," and public displays like kissing rallies, contributed to feelings of belonging—or exclusion.

    “Those years, like 13 to 18... are so precarious in so many ways and people can be cruel to one another and this just feels like a complete, complete explosion of that...” — Interviewer/Co-host (07:56)

Fact vs. Fiction in the TV Movie Adaptation

• The film changed the names and dramatized certain events; some aspects—like the murder weapon (a vegetable-cutting knife left in the car)—were adapted to fit a narrative of non-premeditation.

  “It was not until recently... that I understood the reason they had to get the knife in was so that it was not premeditated.” — Producer/Host (12:31)

• The host and producer discuss that despite these changes, the feeling of the era and social dynamics was captured, but the portrayal of the victim as a "mean girl" is debated:

  “Tori’s character is quite mean. She's not very nice... But everything that I have read... all of the classmates that were interviewed, ultimately, they were like, no. No one deserves to... No one even remotely was suggesting that this deserved... She deserved this.” — Interviewer/Co-host (16:34)

The Impact of the Murder on the Community

• The event left a long-term scar, and most residents and even those close to the case are ambivalent about discussing it publicly decades later.

  “I don't think you can move on from that. You carry that with you, especially when you're a teenager. My gosh. Right. Printed on your psyche for the rest of your life.” — Kelly Martin (53:01)

Interview with Kellie Martin (Angela Del Vecchio/Bernadette Protti)

Preparation for the Role

• Limited Research to Preserve Character Authenticity:
  • Martin intentionally avoided delving deeply into the real-life details before filming, choosing to portray the character based on her interpretation of the script.

    “I didn't know much except that it was based on a true story. And what was I, 17 when I did this? I think I didn't want to know much about it. I kind of wanted to just play Angela as... my version of who she is, and I didn't want to be bogged down by anything true.” — Kellie Martin (27:39)

  • She focused on making her character sympathetic and relatable, deliberately avoiding a monstrous depiction.

    “I wanted her to be as sympathetic as possible. I wanted her to be like the opposite of a monster.” — Kellie Martin (28:24)

Identification with the Character

• Feelings of Not Fitting In:

  • Martin, herself a child actor who always felt like an outsider among peers, deeply resonated with Angela’s alienation and sense of shame.

    “I, like, Angela felt very much like a fish out of water. She really didn't fit in with that community... I felt like I had, like, two left feet. I just never felt like I fit in. And I really. I know that Angela felt so much like that.” — Kellie Martin (29:50)

• Highlight on Shame and Pressure:

  • She noted Angela’s pervasive shame—about her family’s background and not measuring up—as a core motivator, both before and after the crime.

Navigating the Filmmaking Process

• On-Set Dynamics with Tori Spelling:

  • Martin avoided socializing with Spelling, describing herself as “prissy” and Tori as having a “party girl” reputation, which turned into an unintentional form of method acting.

    “So we totally stayed away from each other. ... I was the prissiest thing you ever met. ... So it kind of ended up being a little methody, like I'm Daniel Day Lewis or something. So, like, the makeup trailer, like, we didn't talk...” — Kellie Martin (43:53)

• Influence of Co-Stars and Age-Appropriate Perspectives:

  • She acknowledged learning much from Valerie Harper, who played her mother, and using her own teenage insecurities to enrich the character.

Reflections on Empathy and Modern Contexts

• Evolution of Perspective as a Mother:
  • Now a parent, Martin views Angela with even greater empathy and considers how modern resources (like accessible therapy or online communities) might have changed the outcome.

    “I do feel like as a mom, I definitely see Bernadette in a different way now. ... My 19 year old definitely went through some stuff and I had to really, like, adjust my way of thinking...” — Kellie Martin (47:21)

Responsibility & Lasting Impact

• On Carrying the Role and Its Burden:
  • Martin expresses the weight of playing a real person and her hope to do justice, not cause further pain. She notes that despite the film’s continued cult status, the real community remains haunted.

    “Not that I wanted to make her proud. I wanted to do her justice. And knowing I was playing a real person, it weighed heavily on me.” — Kellie Martin (52:52)

Social Context & Bullying Then and Now

• The team discusses how present-day bullying, the amplification of social groups via social media, and the word’s changing connotations could impact teens in similar situations today.

  “That pressure that a person could go through all of that and bring it to the point of taking a classmate's friend's life without the Internet, without social media, ... that terrifies me to think about today...” — Interviewer/Co-host (48:55)

Notable Quotes & Memorable Moments

• On the Sensation and Curiosity Surrounding Tragedy:

  “People want to be close to tragedy, except when they are the ones who are actually experiencing the tragedy. It's like, why instinctually we are rubbernecking at a car accident.” — Interviewer/Co-host (14:14)

• On Social Hierarchies:

  “It's like I'd call it the two popular groups. ... It totally makes me think of Pretty in Pink.” — Producer/Host (10:15)

• On Filmmaking Choices:

  “I wanted her to just be quiet. Just be quiet. Just stop it. Just stop being that way. Stop being mean and just be quiet is kind of how I envisioned it.” — Kellie Martin (32:54)

• On Pressure and Breaking Points:

  “I read that she, that some of the classmates of Bernadette were saying... the thing that really broke her was not making the yearbook staff. And that was just like that was it.” — Interviewer/Co-host (36:13)

• On Empathy & Parenting:

  “My daughters have kept me very accountable for my behavior, and I'm grateful for that, even though it's hard to hear in the moment.” — Kelly Martin (57:42)

Why the Story Endures

Martin and the hosts agree the film remains a cult favorite due to its quality, pacing, compelling characters, and its representation of the “dark side” of the American high school experience. The murder’s impact—both in its small community and in national popular culture—makes it a story people return to, even as it remains unresolved and painful for those closest to it.

“It's a fascinating crime story with kind of these interesting characters... I think that's why people come back to it.” — Kelly Martin (51:35)

Summary Takeaways

• The tragic murder of Kirsten Costas and its dramatization continue to fascinate and unsettle, serving as a lens to examine adolescent pressure, social exclusion, and the aftershocks of violence.
• Kellie Martin’s approach to playing Angela Del Vecchio balanced empathy, youthful insecurity, and a desire for authenticity.
• The conversation raises important questions about memory, trauma, the line between fact and dramatization, and how much has—or hasn’t—changed for young people facing similar pressures today.
