This project had three goals. One, to provide a more detailed description of injury evidence and biological evidence in sexual assault cases, including their timing relative to arrests. A second goal was to examine the relationship of forensic evidence to arrests. A third goal was to examine injury evidence and biological evidence in certain types of cases in which it may have had greater impact. To achieve these goals, the researchers created analysis data files that merged data from the Massachusetts Provided Sexual Crime Report, forensic evidence data from the two crime laboratories serving the state and data on arrests and criminal charges from 140 different police agencies.

This project explored the use and impact of injury evidence and biological evidence through a study of the role of these forms of evidence in prosecuting sexual assault in an urban district attorney's office in a metropolitan area in the eastern United States. The research questions addressed in this summary overview were as follows:

• How frequent were different forms of injury evidence and biological evidence in the sample?
• Is the presence of injury evidence and biological evidence correlated with the presence of other forms of evidence?
• Which types of cases and case circumstances are more likely to yield injury evidence and biological evidence?
• Do the presence of injury evidence and biological evidence predict criminal justice outcomes, taking into account the effects of other predictors?
• In what ways do prosecutors use injury evidence and biological evidence and what is their appraisal of their impact on case outcomes?

The collection contains 1 SPSS data file, DataArchiveFile_InjuryEvidenceForensicEvidenceandthe ProsecutionofSexualAssault4-7-17.sav (n=257; 417 variables).

This research examined the reliability of the Federal Bureau of Investigation's National Incident-Based Reporting System (NIBRS) arrests data. Data on crime incidents, including data on whether an arrest was made or a summons issued, are collected from hundreds of law enforcement agencies (LEAs) across the country and then combined by the FBI into a national data set that is frequently used by researchers. This study compared arrest data in a sample of cases from NIBRS data files with arrest and summons data collected on the same cases directly from LEAs. The dataset consists of information collected from the Massachusetts NIBRS database combined with data from LEAs through a survey and includes data on arrests, summons, exceptional clearances, applicable statutes and offense names, arrest dates, and arrestees' sex, race, ethnicity and age for a sample of assault incidents between 2011 and 2013 from the NIBRS.

The collection contains one SPSS data file (n=480; 32 variables). Qualitative data are not available as part of this collection.
