Scope of Study

Summary: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.

Methodology

Purpose of the Study: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.
 
Sample:Solved murder cases occurring between 1981 and 1986 from the state of Washington's HITS database.
 
Data Source:official crime records
 
Description of Variables:Collected data include crime evidence, victimology, offender characteristics, geographic locations, weapons, and vehicles.
 
Response Rates:Not applicable.
 
Presence of Common Scales:None
