Changes in methodology:
- Please note that the case closure amount for FY12 and FY13 is based only on the number of closures effected by the detectives in the Major Crimes Division. Closures for FY14 and beyond include all arrests and closures by exception effected by the entire department.
- Starting in FY14, MCPD changed is closure rate methodology. Closure rates for MCPD are calculated as the number of cases that both occurred and were closed (either by arrest or exception) in that fiscal year, divided by the total number of cases in that fiscal year. In the past, the MCPD would present case closures from previous years in the closure rate for the current fiscal year. Changes in our business intelligence tools now adjust closure rates from previous years as cases are closed and/or unfounded.
- To better align reported case closure rates with Uniform Crime Report
standards, MCPD now excludes cases that were closed administratively.
Data from FY15 and onward reflect this change.
Why is this measure important?
Measuring the performance of a police department can be challenging.
However, closure rates help provide an assessment of the department's
goal of managing crime. Closure rates are systematically collected
through the FBI's Uniform Crime Report, allowing for long term trend
Factors contributing to current performance
- There was a 28.5% increase in the number of reported rapes from
308 in CY2016 to 397 in CY2017. The MCPD believes that the increase may
be attributed to the national attention surrounding several high-profile
cases, which has encouraged more victims to come forward and report
being a victim.
- There are very few rape incidents between strangers; subjects are generally known to the victim.
decline in the closure rate may be attributed to a process implemented
last year in which the State's Attorney's Office reviews all cases
before they may be closed or unfounded, thereby increasing the amount of
time it takes to change the offense/case status.
Factors restricting performance improvement
- Length of time between when the incident occurs and when the
victim reports it. In 2017, approximately 23% of the incidents reported
to the MCPD were reported more than a year after they occurred.
- Victims recant statements and refuse to prosecute.
- Unable to serve warrants on subjects who have fled the country.
Performance improvement plan
- Generally speaking, incidents of rape cannot be reduced through
traditional police tactics, since the crimes occur behind closed doors.
Through the cooperative efforts at the Family Justice Center (FJC),the
MCPD Special Victims Investigation Division (SVID) remains committed to
reducing the total number of rapes through non-traditional means, with
services offered to adult victims at the FJC and juvenile victims
through the Department of Health and Human Services' programs, in
coordination with Child Protective Services and Victim Assistance Sexual
Assault Program (VASAP).
- Fill current vacancies to fully staff this section.
- Increase the number of detectives within the Sex Assault Unit by moving vacancies from within other SVID units.
