Cameron Flick: The Math Tutor Serial Killer in Open Season

Overview

Cameron Flick is the principal antagonist in Open Season (2025), the 39th Alex Delaware novel by Jonathan Kellerman. A brilliant math tutor earning $2,500 weekly from wealthy Los Angeles families, Flick operates as a serial killer who murders people he deems threats to his vulnerable students. He uses a .308 Winchester rifle with a custom camouflage finish, treating each killing as a mathematical proof—his computer files are headed “Ansatz” and end with “QED.” Flick’s facade of ordinary professionalism conceals a deeply disturbed individual who began killing at age fifteen, likely murdering his stepfather. His arrest, jailhouse theatrics, and eventual suicide form the climax of the investigation led by Milo Sturgis and Alex Delaware.

Plot Role

Cameron Flick is the killer whose identity is gradually uncovered over the second half of the novel. Alex Delaware connects Flick to three major cases: the murders of Whitney Killeen, Jamarcus Parmenter, and Paul O’Brien, as well as the Ohio shootings of Leonard Wiebelhaus (Flick’s stepfather) and Rainer Steckel. Flick’s role evolves from an invisible background figure—a tutor praised by students like Keisha Boykins, Rhiannon Sterling, and Michael Saucedo—to a suspect once Alex realizes the common thread: Flick protects his “followers” by eliminating anyone causing them distress. His arrest in Chapter 46 (labeled 45 in the EPUB) ends the spree, but his subsequent legal manipulation and suicide in Chapter 50 (Chapter 49) underscore his inability to face defeat.

Motivations and Traits Shown Through Actions

Cameron Flick’s primary motivation is a twisted sense of guardianship. He views his students as intellectually superior beings who must be shielded from harm. The “Ansatz” files document each victim’s offense: Rhiannon Sterling’s stepmother Whitney Killeen caused “hateful and unreasonable demands”; Jamarcus Parmenter harassed Keisha Boykins with “vile, misogynistic doggerel”; Paul O’Brien assaulted Vicki Saucedo, whose brother Michael was Flick’s student; and Errol Moffett was an “outrage” (not further detailed but likely connected to a student). Flick’s writings show he believes these murders are justified—he calls himself a rescuer, not a murderer.

Flick’s traits are cold arrogance, meticulous planning, and a need for intellectual superiority. During arrest he yawns and insults Milo (“redundant moron”). In jail he demands to represent himself, claiming genius, but when Milo reveals Flick was expelled from his math PhD program for failing to produce original work, Flick erupts in rage, banging the table and threatening violence—only to end up sounding “pitiful.” His suicide, using a snapped pen clip and Tylenol overdose, shows he cannot tolerate humiliation or loss of control.

A sexual component is present: semen is found in his car and on a tissue clenched during the surveillance drive. Alex interprets this as part of Flick’s “mastery thing”—the rules don’t apply to him.

Chronological Arc

The narrative reveals Flick’s history in reverse, starting with the present-day investigation and then piecing together his past.

  • Age 11–15: Flick’s mother marries Leonard Wiebelhaus. Flick endures possibly abuse, though his sister Crystal states Leonard was “strict” but not physically abusive. Crystal believes Cameron murdered Wiebelhaus at age fifteen, smiling for days after the “hunting accident.”
  • Age 21: At Oberlin College, Flick is likely the student who caught Rainer Steckel, the janitor, witnessing a masturbation incident. Weeks later, Rainer dies in a hunting accident—Will Steckel believes it was murder.
  • Graduate school: Flick enters a math PhD program but is dismissed two years and five months before the story’s present (around the time the California shootings begin) for failing to produce original work.
  • California killings: Flick targets Whitney Killeen (killed by .308 rifle while she sat in a boat with toddler Jarrod), Jamarcus Parmenter, Paul O’Brien, and Errol Moffett. He also stalks the Streicher family after their daughter bullied a student client.
  • Investigation: Alex Delaware identifies Flick through social media posts and tutoring connections. Surveillance captures Flick at a shooting range with his Winchester .308, consistently hitting neck targets. Flick is arrested after driving slowly through Sepulveda Pass, with semen-stained tissue in hand.
  • Arrest and aftermath: Flick fires two court-appointed lawyers, represents himself, and interviews with Milo and Alex. After Alex reveals Flick’s academic failure, Flick becomes violent but is subdued. Three days later, he commits suicide in isolation.

Relationships

  • Students (Keisha, Rhiannon, Michael, Shania): Flick forms parasitic bonds, positioning himself as protector. The relationships yield intelligence about targets and provide emotional justification.
  • Sister Crystal Jo Wiebelhaus: Terrified of her brother since childhood, she describes cruelty to animals and people. She offers no evidence but confirms she believes he killed their stepfather.
  • Stepfather Leonard Wiebelhaus: Strict disciplinarian, likely resented. Murdered when Flick was 15.
  • Mother Felicia Sue: Uncooperative with police; possibly fearful of Cameron.
  • Milo Sturgis and Alex Delaware: Adversaries. Flick attempts intellectual domination, fails, and reacts with rage. He addresses Milo as “porcine dolt” and claims the “session over” repeatedly.

Key Decisions and Consequences

  1. Murder of Leonard Wiebelhaus (age 15): Establishes his pattern of violent problem-solving. Gets away with it, fueling belief in his invulnerability.
  2. Expulsion from PhD program: Unable to produce original work, he channels his need for superiority into killing. The timing aligns with the first California murders.
  3. Murders of student threats: Each murder is planned with precision (e.g., arranging Whitney Killeen’s death while Jarrod Sterling is present). Consequences: removal of targets but also forensic evidence—ballistics match, DNA in car, and incriminating computer files.
  4. Stalking the Streicher house: Driven by a student’s complaint. He parks, masturbates, and leaves tissue. This leads to his arrest because the police have him under surveillance.
  5. Refusal to cooperate and legal games: Fires lawyers, attempts self-representation. Consequence: delays case but ultimately isolates himself. His suicide prevents a trial but also denies victims’ families closure.

Theme and Symbol Connections

Cameron Flick embodies several themes from the novel:

  • Protection of children (or students): His central rationalization. The theme is explored in how far people go to shield those they care for. Alex and Robin discuss “selfish love” and parents hiring killers for children’s futures. Flick represents an extreme, pathological version of this.
  • Mathematical justification of murder: Flick views each killing as a proof: setting the framework (Ansatz), establishing a premise (the student’s distress), and concluding with QED (Latin for “thus it is proved”). Symbols include the .308 rifle with its custom Cerakote finish, the unpassworded computer files, and his mathematical jargon during arrest.
  • Predation and vulnerability: Flick preys on the vulnerable (those who threaten his students) but also on the vulnerabilities of the system—his ordinary appearance (“blandness of his DMV photo”) and his ability to hide in plain sight as a tutor. The hunting expression captured in the gallery photo mirrors Paul O’Brien’s predator look at the Chanel party.
  • Hollywood illusion and ambition: Flick lives modestly despite high earnings, but his clients are wealthy families obsessed with college admissions. The tutor-student relationship is transactional, built on the illusion that success is controllable. Flick’s murders expose the dark side of that ambition.
  • Moral ambiguity in justice: Flick’s deaths spare families traumatic trials, as Alex notes after the suicide. But the means—extrajudicial killing—are indefensible. The novel questions whether justice can ever be purely mathematical.

Five Book-Specific Questions and Answers

1. How does Cameron Flick justify his murders?
Flick views himself as a protector of “followers” (his students). In his files, he documents each victim’s “offenses” against a student, then executes what he considers a justified elimination, ending with “QED” to frame it as a logical proof. Alex Delaware theorizes that Flick needs a noble justification to feed his ego and libido.

2. Why does Flick fire his court-appointed lawyers?
Flick fires Lance Guidot for being “not smart enough” and Marcia Kendall after only 26 hours for “insufficient attention to the gravity of my situation.” He intends to represent himself, believing his own intellect superior. Milo and Alex interpret this as delay tactics and narcissism. The judge, described as a “total moron” who believes bad guys can do no wrong, appears to tolerate the games.

3. What evidence directly ties Flick to the murders?
The ballistics match from the .308 Winchester Featherweight found in his armoire. His computer contains detailed “Ansatz” files rationalizing each killing. Semen found in his car and on a tissue matches DNA. Surveillance shows him shooting at a range, consistently hitting the neck area where his victims were shot.

4. Does Flick show any remorse or vulnerability?
No remorse is shown. He maintains arrogance throughout, even during arrest. The only moment of vulnerability comes when Milo reveals Flick was expelled from his PhD program. Flick erupts in rage, bangs the table, and threatens “Don’t think it’s over”—but in a “pitiful” voice. His suicide three days later may indicate inability to cope with public humiliation, but Alex argues it also avoids a penalty he could not control.

5. What does Flick’s suicide mean for the case and the victims’ families?
Milo worries his harsh questioning caused the death, but Alex counters that Flick was deeply disturbed and that the suicide spares families a traumatic trial. The prosecutor seems relieved, while a psychologist weeps. Alex writes down the victims’ names and studies their photos to counter any sympathy, concluding there is no reason to give Flick’s death more thought. This reflects the novel’s theme of moral ambiguity: justice is served, but imperfectly.
