This website includes selected offense reports taken by the Frederick County Sheriff’s Office (shown as FCSO), the Brunswick Police Department (shown as BPD), and the Thurmont Police Department (shown as TPD). It does NOT include any reports taken the Frederick City Police Department and the Maryland State Police. The map does NOT show calls for service. It shows offense or incident reports. These are where a deputy takes a report, which is reviewed, and then classified. Except for Vandalism all the crimes shown on the map are “Part I” crimes. These are crimes that are more serious. Rapes and sex offenses are not displayed on the map. The Sheriff’s Office did not include these offense locations to protect the privacy of the victims. Please refer to the UCR table for 2007. It shows the number of rapes and sex offenses that were handled by the Sheriff’s Office in year 2007.

The crimes on the site are updated twice a month with three months of data shown on the map. Every attempt will be made to have the updates on the site by the 15th and 30th of each month.

Each month offense report data is downloaded in table format from the Frederick County Sheriff’s Office Records Management System. This table has many fields, two of which are the offense and the address. This information is imported into a GIS (Geographic Information System) program, ArcGIS, which runs the CrimeView extension. CrimeView uses the County’s street data to “geocode” or match the crime address to the appropriate street segment. Once it finds this, it places a point. The type of point is determined by the offense (see the legend on the map for various symbology).

There are three ways of viewing the crimes on the map. You can either select a neighborhood or a zip code from the two dropdown lists on the left. Otherwise, you can use the zoom tool to zoom in on a particular area of the county. The neighborhood list is not a complete list. If you do not see your neighborhood listed, please check back as neighborhoods will continue to be added.
