FBI Behavioral Science Unit

The FBI Behavioral Science Unit is represented in the investigation by senior federal official Leimert Fusco, whose contact with Milo Sturgis brings a possible federal partnership—and a body of comparative case material—into the inquiry surrounding Eldon Mate’s murder. The novel presents the unit chiefly through this proposed collaboration and Fusco’s investigative work, rather than through a detailed account of its internal structure or methods.

Federal Contact and Proposed Consultation

Fusco, described as a PhD originally from Virginia and a prominent figure in the unit, contacts Sturgis after the detective’s call to VICAP appears to have triggered federal interest. The approach is personal as well as institutional: Fusco proposes a meeting, and his fax identifies him as Assistant Deputy Director of Behavioral Science while offering help.

Sturgis is wary. He suspects Fusco wants to draw on the local investigators’ thinking, then either disengage if the case proves hopeless or join the investigation and claim some credit if it advances. That account is Sturgis’s interpretation, not an established description of the unit’s policy. He postpones the meeting and plans to keep doing so unless his own superiors direct him otherwise. The exchange gives the unit access to the case without making its participation an accomplished fact.

From Mate to Michael Burke

The federal overture initially appears connected to Mate’s killing, but the conversation soon turns to Michael Burke. When Sturgis asks what Fusco is saying, Alex Delaware answers with Burke’s name; neither investigator can immediately explain why it sounds familiar. The connection thus arrives first as a loose investigative association, not a settled conclusion.

Fusco’s substantial case compilation later gives that association evidentiary weight. At 3:22 a.m. on Thursday, after finishing the volume and reviewing its photographs again, Alex notices an image from an unsolved Washington State murder. Fusco had regarded four killings committed while Burke was a medical student as consistent with Burke’s technique, in part because the victims had been left propped against or near trees. The compilation provides a basis for comparison, but the resemblance is presented as an investigative judgment rather than proof that Burke committed those crimes.

Case Material and Investigative Reach

One case in the compilation concerns Marissa Bonpaine, a twenty-year-old waitress last seen at Seattle’s Pike Place Market. Her body was found a week later in a remote part of the Olympic National Forest, positioned before a fir tree. Investigators found no footprints; rain and the forest floor further complicated the recovery of forensic evidence. Her injuries included a throat slash, abdominal mutilations, sexual posturing, and a deep trapezoidal wound above the pubic bone. Alex recognizes disturbing similarities between this account and the violence under investigation.

The material’s effect is not simply to supply a suspect’s name. It extends the inquiry across jurisdictions and earlier cases, inviting comparison among scene placement, wounds, and the apparent care taken to leave little trace. Alex’s later return to the Bonpaine file leads him to notice a small notation by the first Seattle officer on the scene, Robert Elias, cross-referenced in a footnote. The excerpt does not disclose the notation’s contents, so its significance remains unresolved here.

Institutional Presence in the Narrative

The unit’s role is mediated through individuals and documents: Fusco’s federal rank, his proposed meeting with Sturgis, and the compilation Alex studies. Sturgis’s suspicion about credit and Alex’s painstaking re-examination of the photographs keep institutional authority from becoming a substitute for local scrutiny. The resulting inquiry depends on testing a suggestive cross-case pattern against specific details, while leaving open whether the unit will formally join the investigation or whether the apparent connection to Burke will hold.
