Filtering out of cases at the police level accounted for the termination of 52.6 percent of the cases. Police and victim apprehension of proceeding with the case (cases viewed as unfounded or where no complaint is filed or charges are dropped) and the failure to identify and locate a suspect were major factors in attrition. At the level of Crown Counsel, 5.7 percent of charges were terminated for lack of evidence; an additional 4.7 percent were resolved by plea bargaining of charge or sentence. At the court level, 7.6 percent were terminated by case dismissal or acquittal. Of 51 persons (24.2 percent) found guilty, 21 were found guilty of reduced charges or received reduced sentences through plea bargaining. Factors related to case attrition included absence of a medical examination, victim criminal record and lack of victim injury (at the police level only). 5 tables and 19 references.
