DJS

Washington College GIS performs a colocation and dual supervision analysis bi-monthly for Department of Juvenile Services (DJS) and Maryland Community Supervision (MCS), formerly Department of Parole and Probation.

The analysis requires us to use data from DJS, MCS, and the Sex Offender Registry. Multiple selections and queries are performed on these datasets to determine the number of juvenile offenders living with adult offenders, and the number of juvenile offenders living with sex offenders. These two resulting datasets are part of the colocation analysis. The dual supervision analysis identifies offenders that are located in both the DJS dataset, and the MCS dataset. Case workers in both DJS and MCS are using this analysis to follow-up on each case where an offender they are supervising is identified as either being collocated or dual supervised. This information is reported at StateStat meetings by both agencies. Maps showing both addresses and spatial location of colocation and dual supervision are made and used by each agency. Performing this level of analysis on approximately 6,300 DJS records, 100,000 MCS records, and 10,000 SOR records is very time consuming.

In addition to the Co-Location and Dual Supervision Analysis that we provide for Department of Juvenile Services, we also provide them with maps on demand. Requests include mapping juveniles based on case type, as well as mapping juveniles with felonies and violent crimes. Mapping can be provided on a statewide level, as well as broken down into the specified regions. Other law enforcement agencies throughout the state often request data and mapping products that utilize the DJS data we receive.
