Impact of Forensic Evidence on Arrest and Prosecution   [open pdf - 1MB]

"The National Institute of Justice (NIJ) grant solicitation, 'Social Science Research on Forensic Science' (NIJ-2011-2822), was heavily reliant on the NIJ study, 'The Role and Impact of Forensic Evidence in the Criminal Justice Process' (Peterson, Sommers, Baskin, and Johnson, 2010). The objectives of Peterson et al., (2010) were to 1) 'Estimate the percentage of crime scenes from which one or more types of forensic evidence is collected;' 2) 'Describe and catalog the kinds of forensic evidence collected at crime scenes;' 3) 'Track the use and attrition of forensic evidence in the criminal justice system from crime scenes through laboratory analysis, and then through subsequent criminal justice processes;' 4) 'Identify which forms of forensic evidence contribute most frequently (relative to their availability at a crime scene) to successful case outcomes' (Peterson et al. 2010, Pg. 11-12). Peterson, et al. (2010) analyzed crime lab, investigative, and prosecutorial case file information of crimes that fit into one of five crime categories: assault; burglary; homicide; rape; and robbery. Peterson et al. (2010) concluded their analysis by making ten recommendations regarding future research on the utility of forensic evidence. The current study, 'The Impact of Forensic Evidence on Arrest and Prosecution', addressed several of these recommendations via a methodology that informs the four research objectives listed above."
