Chapter 28: Building the Case Against Amanda Fisk

⚠️ Spoiler Notice
This chapter summary reveals major plot developments from Chapter 27 of Lethal Prey, including the identification of a suspect and key background details. If you haven't read the chapter, proceed with caution.

Summary

Virgil and Lucas decide to focus their investigation on prosecutor Amanda Fisk. They learn from true crime researcher Dahlia Blair that Fisk married Timothy Carlson in September, four months after Doris Grandfelt’s murder—contradicting Fisk’s earlier claim that she only began dating Carlson after Doris’s death. The team works with true-crimers to gather circumstantial evidence. Karen Moss discovers that Fisk grew up on Hattie Lane in Woodbury, one block from Shawnee Park where Doris’s body was found. Virgil and Lucas travel to Eau Claire to interview Fisk’s father, Harlan, and his wife Ruth. Harlan reveals that Fisk had a difficult childhood: her mother abandoned her as a baby, she was forced into a basement room when her uncle Don moved in (and likely abused her), and she witnessed a friend’s gruesome death in a traffic accident as a teenager. Ruth describes Fisk as "mean" and says she looked at people "like they were bugs." Lucas notes that Fisk fits the profile of a serial killer with a traumatic upbringing. The chapter ends with Virgil and Lucas updating Lara Grandfelt, who vows to pursue a civil suit if the criminal case falters.

Key Events

Virgil and Lucas decide to "sic" true-crime researchers on Amanda Fisk’s background.
Dahlia Blair confirms that Fisk married Carlson four months after Doris’s murder.
Karen Moss links Fisk’s childhood home to Shawnee Park, location of Doris’s body.
Virgil and Lucas interview Fisk’s father Harlan and stepmother Ruth in Eau Claire.
Harlan reveals Fisk’s traumatic childhood: maternal abandonment, possible sexual abuse by uncle Don, and witnessing a friend’s death.
Lucas and Virgil update Lara Grandfelt on the case; she pledges a civil suit if needed.
The team pursues DNA results from Chicago and plans to check Fisk’s credit card records for gasoline purchases near Virgil’s stable fire.

Character Development

Virgil Flowers – Shows increasing confidence in his theory: he pushes hard for background research on Fisk and tells Lucas he believes she’s a serial killer. His personal life also advances as he announces his plans to marry Frankie.

Lucas Davenport – Takes a lead in interviewing witnesses and planning strategy. His experience helps him recognize Fisk’s childhood as a “classic serial killer childhood,” drawing on his familiarity with criminal psychology.

Amanda Fisk – Although not present in the chapter, her profile deepens through others’ accounts. Her father describes her as emotionally distant; her stepmother calls her “mean.” The hints of early abuse and trauma paint a picture of a potentially remorseless killer.

Lara Grandfelt – Shows resilience and pragmatism. Rather than demanding immediate retribution, she calmly considers a civil lawsuit as an alternative if criminal conviction proves elusive.

Harlan Fisk – Appears as a sympathetic but flawed figure: he acknowledges his daughter’s hard upbringing but also admits he didn’t know her well. His speculation about his brother-in-law’s abuse is the most concrete evidence of Fisk’s troubled past.

Themes, Symbols, or Motifs

Circumstantial Evidence vs. Hard Proof – The chapter repeatedly emphasizes the lack of DNA or forensic evidence against Fisk. Duncan notes that her scrubbing of Carlson’s DNA is itself a sign of guilt, but the team still lacks a smoking gun. This creates tension between the investigators’ certainty and their legal limitations.
The Weight of Childhood Trauma – Harlan’s detailed account of Fisk’s early years—abandonment, possible abuse, a violent death she witnessed—reinforces the theme that extreme childhood experiences can shape a killer. Lucas explicitly names this as a “classic serial killer childhood.”
The Reward as Motivation – The true-crimers are driven partly by the five-million-dollar reward. Karen Moss’s excitement (“Am I good, or what?”) shows how financial incentive fuels the investigation, blurring the line between justice and profit.
The Mansion and the Dungeon – Fisk now lives in a Summit Avenue mansion, but her childhood quarters were a basement she called “the dungeon.” This contrast highlights the gap between her present professional success and her degraded past.

Why This Chapter Matters

Chapter 27 is the turning point where the investigators shift from suspicion to active pursuit of Amanda Fisk. It provides the most detailed psychological portrait of a suspect so far, connecting her troubled past to her alleged crimes. The chapter also solidifies the team’s strategy: pile up circumstantial evidence, interview family, and use every legal and extra-legal means (including NSA sources via Letty) to build the case. The interview with Harlan Fisk yields critical backstory that makes Fisk a plausible serial killer, while Lara Grandfelt’s promise of a civil suit suggests a path to justice even if the criminal case fails. This chapter advances the plot from theory to confirmation, setting up the final act.

Study Questions and Answers

What key piece of information does Dahlia Blair provide that contradicts Fisk’s earlier statement to Virgil?
Blair tells Virgil that Fisk and Carlson married in September, four months after Doris’s murder. Fisk had previously claimed she only began dating Carlson after Doris’s death, but the marriage date suggests the relationship began earlier, giving Fisk a possible motive of jealousy.
How does Lucas interpret Fisk’s childhood as “a classic serial killer childhood”?
Lucas points to several factors: early maternal abandonment, potential sexual abuse by an uncle, displacement from her own room to a basement “dungeon,” and the traumatic death of a friend she witnessed. These elements mirror patterns often seen in the backgrounds of serial killers.
What alternative to a criminal conviction does Lara Grandfelt propose, and why does she think it could succeed?
Grandfelt says she will sue Fisk for wrongful death in civil court if there is no criminal conviction. Because a civil suit only requires a preponderance of evidence (not proof beyond a reasonable doubt), she believes she can win and strip Fisk of her money and property.
