Petra Connor: The Detective Who Connects the Killings in Open Season

Overview of Petra Connor

Petra Connor is a senior homicide detective with the Los Angeles Police Department, assigned to Hollywood Division. First introduced in the narrative when she calls Milo Sturgis about the murder of Paul O'Brien, she quickly becomes a crucial partner in the joint task force investigating a series of precision sniper killings. Described as young, athletically slender, and elegantly dressed, Petra possesses a "cool, confident voice" and a reputation for efficiency earned through years of fast-tracked murder investigations. Her appearance—clean-jawed ivory face and black bob—contrasts with the gritty Hollywood environment she works in. Petra is not a newcomer to the series, but in Open Season she takes on a central role linking a fresh homicide to a two‑year‑old cold case.

Plot Role and Contribution

Petra's key contribution is discovering the ballistics match between the rifle that killed Paul O'Brien and the one used in the unsolved murder of aspiring rapper Jamarcus Parmenter. This discovery transforms a seemingly isolated revenge killing into a pattern of targeted shootings. When she calls Milo, she brings not only evidence of O'Brien's death but also the presence of Marissa French's ID in O'Brien's apartment—a crucial link connecting the dumped body case to a new homicide. Petra's methodical approach is evident: she examines the crime scene, identifies the likely trajectory from a neighboring building, and secures the scene before calling Milo. She then presents forensic evidence at the team meeting, including how the shooter entered O'Brien's building through an unlocked service entrance and a delivery ramp. Her role extends beyond investigation; she helps coordinate the surveillance of suspect Cameron Flick, reporting his movements and participating in the eventual arrest. Petra's willingness to collaborate, despite initial departmental friction, drives the investigation forward.

Motivations and Traits Shown Through Actions

Petra is motivated by a professional commitment to solving murders, unaffected by jurisdictional politics. When Captain Shubb (Milo's captain) and Art DiMeo (Petra's captain) force Milo and Petra to work together due to their personal relationship, Petra accepts the collaboration without complaint, focusing on the case rather than the political awkwardness. Her actions demonstrate a strong work ethic: she initiates the ballistics comparison without being asked, works long hours canvassing, and remains actively involved in surveillance. She is also tactful and diplomatic, as seen when she tells Milo "I'm kind of looking forward to it" about working together. Her efficiency is paired with a sharp analytical mind: she quickly notes the unusual nature of the .308 full‑metal‑jacket round and considers military sniper possibilities but also recognizes that a civilian could achieve similar accuracy. Petra shows empathy for victims, yet maintains professional detachment; she describes finding Marissa's ID as "creepy" but moves on to the logistics of evidence tagging.

Chronological Arc

Petra first appears in Chapter 6, when she calls Milo to report Paul O'Brien's murder and the link to Marissa French. She greets Milo and Alex at the Hollywood crime scene, lifts the yellow tape, and briefs them. Over the following chapters, she collaborates with Milo, Raul Biro, and retired detective Hawes Buxby. In Chapter 10 (as per evidence), it is revealed that she discovered the ballistics match to Jamarcus Parmenter by asking around about rifle murders and finding a cold case file. She then participates in the task force meeting in Chapter 11, presenting the evidence. In Chapter 29, she reports that thirty‑nine traffic tickets near O'Brien's murder scene all led to alibis. She joins the surveillance of Cameron Flick in Chapters 42–44, reporting his movements. At the arrest in Chapter 45, she is part of the surround strategy. After Flick's suicide in jail, her role in the narrative concludes, though she remains present as a member of the team.

Relationships

Petra's primary relationship is with Milo Sturgis. They have a history of working together, indicated by their easy rapport; Milo calls her "kid" and she teases him. Their collaboration is mutually respectful. Petra also interacts effectively with Raul Biro, her partner, who assists with canvassing. With Alex Delaware, she welcomes his input, asking Milo if she can tap his brain. Her interaction with retired detective Hawes Buxby is professional, as he shares information on the Parmenter case. Petra has no family or personal backstory revealed in the novel; she is defined almost entirely by her work. Her relationship with her captain, Art DiMeo, is implied to be politically complicated, but Petra does not let it affect her duty.

Key Decisions and Consequences

Decision to search for rifle murders: Petra actively asks around and searches records, leading to the ballistics match. This broadens the investigation and forces the creation of a joint task force.
Decision to call Milo immediately: Instead of handling O'Brien's murder alone, she includes Milo because of Marissa French's ID. This ensures evidence is shared and prevents jurisdictional conflict.
Decision to cooperate under forced collaboration: Despite the political pressure, Petra works seamlessly with Milo, avoiding friction that could slow the case.
Decision to participate in surveillance: She commits resources to tracking Flick, which leads directly to his arrest.
Decision to present evidence clearly at the team meeting: Her thorough presentation helps align the team and focuses the investigation on Gerald Boykins and later Flick.

These decisions are explicitly supported by the evidence: the ballistics discovery is recounted in Chapter 10, the call in Chapter 6, and the meeting in Chapter 11.

Theme and Symbol Connections

Petra embodies the theme of protection of children indirectly; her work seeks justice for victims like Marissa French and Jamarcus Parmenter, who were vulnerable to predators. However, her character more directly connects to moral ambiguity in justice. Petra is willing to accept that O'Brien's death may be vigilante justice, but she does not condone it—she simply investigates without prejudice. Her discovery of the ballistics link also ties to the theme of mathematical justification of murder, as the precision of the shootings suggests a cold, calculating mind. The symbol of the .308 rifle, which ties together O'Brien and Parmenter, represents the mechanical, distant nature of the killer. Petra herself symbolizes the dedicated public servant who operates within the system, never crossing ethical lines despite the temptation to cut corners. Her professionalism contrasts with the killer's rationalized violence.
