Improving the Investigation of Homicide and the Apprehension Rate of Murderers in Washington State, 1981-1986 (ICPSR 6134)
This data collection contains information on solved murders occurring in Washington State between 1981 and 1986. The collection is a subset of data from the Homicide Investigation Tracking System (HITS), a computerized database maintained by the state of Washington that contains information on murders and sexual assault cases in that state. The data for HITS are provided voluntarily by police and sheriffs' departments covering 273 jurisdictions, medical examiners' and coroners' offices in 39 counties, prosecuting attorneys' offices in 39 counties, the Washington State Department of Vital Statistics, and the Uniform Crime Report Unit of the Washington State Association of Sheriffs and Police Chiefs. Collected data include crime evidence, victimology, offender characteristics, geographic locations, weapons, and vehicles.
One or more data files in this study are set up in a non-standard format, such as card image format. Users may need help converting these files before they can be used for analysis.
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

Scope of Study
Study Purpose: This data collection is constructed from the Homicide Investigation Tracking System (HITS), a computerized database maintained by the state of Washington. HITS was designed to (1) provide law enforcement officials with information regarding incidents of murder, (2) provide analysis of these incidents such as links between victims, offenders, and cases, and (3) provide investigators with resources, including names of experts and technical assistance in investigating such cases.
Study Design: The HITS database consists of murder cases, both solved and unsolved, occurring in Washington State between 1981 and 1986. Incidents tracked include murders, attempted murders, missing persons when foul play is suspected, and unidentified persons believed to be victims of murder. The system relies on law enforcement agencies in Washington State to submit information voluntarily to HITS investigators. This data collection consists of information on solved murder cases only.

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed recodes and/or calculated derived variables.
