Important Notes

The Criminal Investigation Bureau (CIB), a specialized unit within the Special Operations Division, serves as the investigative arm of the Mercer County Sheriff’s Office. Our team of highly-trained detectives is dedicated to investigating major crimes, ensuring justice for victims, and upholding the safety of our community.

Our Focus Areas

  • Major Crimes Investigation: We investigate a wide range of serious offenses, including homicide, robbery, sexual assault, fraud, and drug trafficking. Our detectives work collaboratively with patrol deputies, forensic experts, and other law enforcement agencies to gather evidence, identify suspects, and build strong cases for prosecution.
  • Child Abuse Investigation: We are committed to protecting the most vulnerable members of our community. Our specially-trained detectives investigate allegations of child abuse and neglect, working closely with Child Protective Services to ensure the safety and well-being of children.
  • Multidisciplinary Investigative Team (MDIT): The CIB actively participates in the Mercer County MDIT, a collaborative effort involving law enforcement, child protective services, medical professionals, and victim advocates. This team approach ensures a comprehensive and coordinated response to child abuse cases.
  • Digital Forensics: We utilize cutting-edge technology to investigate cybercrimes and extract digital evidence from computers, cell phones, and other electronic devices. Our digital forensics experts are trained in the latest techniques to uncover critical information that can help solve complex cases.
  • Forensic Photography: We employ forensic photography to document crime scenes and evidence accurately. Our photographers use specialized techniques to capture high-quality images that can be used in court proceedings.

Specialized Training

Our detectives receive ongoing training in advanced investigative techniques, including:

  • Interview and Interrogation: Building rapport with witnesses and suspects, eliciting truthful information, and obtaining confessions when appropriate.
  • Crime Scene Investigation: Preserving and documenting evidence at crime scenes, recognizing patterns, and reconstructing events.
  • Forensic Science: Understanding the principles of forensic science and applying them to investigations.

Collaboration with the Community

We believe that community involvement is essential to effective crime prevention and investigation. We encourage citizens to report suspicious activity and cooperate with our detectives during investigations. Your information can be crucial in helping us solve crimes and bring perpetrators to justice.
