Tri County Regional Forensic Laboratory

Laboratory Services Guide


In February of 2008, the Anoka County Sheriff’s Office entered into a cooperative agreement with Wright and Sherburne Counties to make possible the Tri County Regional Forensic Laboratory.  This agreement combines the resources of the three counties in order to provide forensic services to the law enforcement community.  Currently the laboratory is in the process of obtaining ISO/IEC 17025:2005 ASCLD/LAB-International Accreditation aiming for completion in early 2014. In addition, through a collaborative agreement with Hamline University, students interested in a career in forensic science can obtain an internship within one of the specific disciplines.
