The Tacoma Police Special Investigations (SI) Section is responsible for investigating Narcotic and Vice-related crimes.  SI’s mission is to address street-level narcotic and prostitution complaints, identify and remove drug houses in the community, and dismantle and/or disrupt mid-level to high-level drug trafficking organizations.  SI Officers operate in a covert fashion and utilize a variety of investigative methods to successfully investigate narcotic/prostitution-related activity.


In addition, SI works collectively with other State and federal law enforcement agencies to attack drug and prostitution activity.  SI has Officers assigned to DEA Task Forces reference narcotic investigations, as well as an Officer assigned to the FBI’s Center for Missing and Exploited Children Task Force.  Working collaboratively with these federal agencies allows for greater resources to address the issues at a local and regional level and disrupts the follow of illegal activity, narcotics/prostitution, which flow into the Tacoma-Pierce County area.


Forensic Services Section

The Tacoma Police Department’s Forensic Services Section consists of a Crime Scene Unit and a Latent Print Unit.  Their mission is to serve the criminal justice needs of the community through education and the application of accepted scientific techniques to the preservation and analysis of physical evidence.


Crime Scene Technicians and Forensic Specialists respond to crime scenes ranging from burglaries to homicides.  Their responsibilities include photography; latent print processing; evidence collection and preservation, both at the crime scene and in the laboratory; shoe and tire casting; crime scene diagrams; and courtroom testimony.


Forensic Latent Print Examiners perform scientific examinations in the area of friction ridge analysis, including the comparison of latent finger and palm prints.  Latent Print Examiners also provide expert witness testimony regarding their findings in a court of law.
