The four primary goals of The Detroit Sexual Assault Kit Action Research Project (DSAK-ARP) were: To assess the scope of the problem by conducting a complete census of all sexual assault kits (SAKs) in police property. To identify the underlying factors that contributed to why Detroit had so many un-submitted SAKs. To develop a plan for testing SAKs and to evaluate the efficacy of that plan. To create a victim notification protocol and evaluate the efficacy of that protocol. To conduct the census and investigate factors that contributed to untested SAKs, The study investigated police and other public records, interviewed public officials and employees and manually cataloged untested SAKs to conduct the census and gather information as to the decision making processes as to why the SAKs remained untested. A random sample of 1,595 SAKs were tested as part of developing a SAK testing plan. Kits were divided into four testing groups to examine the utility of testing SAKs for stranger perpetrated sexual assaults, non-stranger perpetrated sexual assaults and sexual assaults believed to be beyond the statute of limitations. The final testing group split SAKs randomly into two addition sample sets as part of an experimental design to examine whether the testing method of selective degradation was a quicker and more cost efficient approach that offered satisfactory levels of accuracy when compared to standard DNA testing methods. A two stage protocol was created to inform sexual assault victims that their SAKs had been tested, discuss options for participating with the investigation and prosecution process and connect the victim with community services.
