Frank Janderman

Frank Janderman turns up as one of the working investigators pulled into the widening task force, a law-enforcement professional trying to hold his footing as the case grows larger and more political than anything he's used to. He is practical, a little wary of the outsiders brought in to profile the killer, and focused on the job in front of him.

Jesse C. Boyd plays him with the flat, tired competence of someone who has seen bureaucracy slow down real urgency before. He's not a showy presence, but that groundedness matters in a series built on theory and interpretation — Janderman is a reminder of the actual, grinding police work underneath the psychology.
