Sheriff's Office Regional Firearms Identification Laboratory

Mission Statement

The Sheriff's Office Firearms Identification Laboratory is committed to providing objective and scientifically reliable forensic analysis and other appropriate technical support for the criminal justice system within Harris County and surrounding jurisdictions.

Sheriff's Office Firearms Identification Laboratory:

The Firearms Identification Laboratory, officially named the Harris County Sheriff's Office Regional Firearms Identification Laboratory , was created as a result of a grant award from the Criminal Justice Division of the Governor's Office of the State of Texas. This grant helped fund laboratory operations for the first five years of operation. The laboratory began doing casework in July of 1999. In January 2006, the Harris County Sheriff's Department Regional Firearms Identification Laboratory received accreditation by the American Society of Crime Laboratory Directors Laboratory Accreditation Board (ASCLD/LAB) and the Texas Department of Public Safety. The Firearms Identification Laboratory receives firearms and firearms related evidence not only from the Harris County Sheriff's Office, but also from dozens of law enforcement agencies throughout southeast Texas . The Firearms Identification Laboratory is a major contributor to the National Integrated Ballistics Identification Network (NIBIN) using the imaging technology of the Integrated Ballistics Identification System (IBIS). With the IBIS system the Firearms Identification Laboratory is able to support and assist criminal investigations by linking together criminal cases that were not known to be related using firearm evidence. This system was obtained from the Bureau of Alcohol, Tobacco, Firearms and Explosives through Federal appropriations and support from several local representatives of the United States Congress. Current staffing within the Firearms Laboratory consists of the Laboratory Manager, four court qualified firearms and tool mark examiners, one firearms technician, one IBIS Clerk and one clerical person. Since beginning operations in 1999 the Firearms Identification Laboratory has seen a steady increase in the workload. During 2000, the first full year of operation, the laboratory received approximately 1000 cases. Five years later in 2005 the workload had increased by 54% with the laboratory receiving 1644 cases. The laboratory continues to grow and the caseload for 2006 is anticipated to reach 1850-2000 cases.

Located at 1885 O.S.T. within the Harris County Medical Examiner's Building, this section provides a full range of forensic firearms and tool mark identification services to any agency in southeast Texas; these examinations include:
