What Jennifer “JJ” Jareau Does and Why It Matters
Jennifer “JJ” Jareau is the Communications Liaison and later a profiler within the fictional Behavioral Analysis Unit (BAU), serving as the bridge between on-scene response and national media or victim families. In this role she translates complex investigative details into clear public information, manages family interactions, and supports team operations. This profile explains her core functions, how the position differs from sworn agents, and the narrative uses of the character across the long-running series.
Role and Responsibilities in the BAU
Within the BAU framework, the Communications Liaison acts as the public-facing point for the unit. The position is responsible for carefully delivering information to press and community stakeholders while protecting active investigations and victim privacy. The role also includes direct family engagement and coordination with partner agencies when timely, accurate communication affects safety or cooperation.
Communication and Media Management
JJ handles press inquiries, drafts statements, and appears in interviews to provide consistent, factual updates. This reduces misinformation and helps maintain operational integrity when details could influence public behavior or suspect actions.
Family and Victim Interaction
She serves families and victims with clear, compassionate messaging. By keeping lines open between the BAU and those affected, the unit sustains trust and gathers information that can support case progression.
Operational Support
Beyond speaking duties, the liaison logs communication outcomes, updates command on public sentiment, and flags concerns that might require strategy changes. This behind-the-scenes work keeps the team aligned with external realities.
Distinguishing the Role from Field Agents
Unlike profilers and agents who conduct interviews, surveil, and enter scenes, the Communications Liaison typically remains at headquarters or nearby command centers. The position focuses on message control, not direct evidence collection, which influences training, clearance levels, and day-to-day tasks.
