The Investigations Division includes the Criminal Investigations Unit and the Special Investigations Unit.  

Criminal Investigations Unit (CIU)

The CIU detectives' primary duty is to conduct secondary investigations for felony crimes.  Examples include homicides, robberies, arsons, prostitution, identity thefts and fraud.  Detectives have many investigative specialties and a high level of training and experience.  The section includes a Detective Sergeant and four general case detectives.

Special Investigations Unit (SIU)

The SIU consists of a Sergeant, three SIU Detectives, a School Resource Officer (SRO), and a Crime Analysis Detective.

  • The SIU detectives primarily conduct felony sexual assault investigations, Child Protective Services referral investigations and Adult Protective Services referral investigations. They also coordinate the registered sex offender notification and monitoring program.
  • The School Resource Officer serves the Bothell High School.  The SRO strives to bridge gaps between police officers and young people, helping to increase positive attitudes toward law enforcement.  During the summer months, the officer is busy preparing for the next school year, working on special projects, and assisting with regular Patrol duties. The SRO program provides: 
    • Visible, active law enforcement on the high school campus
    • Classroom resources for instruction in law enforcement related education, violence diffusion, safety programs, and alcohol and drug prevention.
    • A team approach with the officer, faculty and administration working together to solve problems in the school community.
    • A safer school environment.
  • The crime analysis detective analyzes crime trends and provides timely information that assists Department members and the community with targeted enforcement and strategy development.
