Hennepin County Sheriff’s Office:  Criminal Information Sharing and Analysis
By Brian Paulson, Hennepin County Sheriff’s Office

In February 2007, the Hennepin County Sheriff’s Office established CISA (Criminal Information Sharing and Analysis) under the direction of Sheriff Rich Stanek.  CISA was established to assist in the prevention and suppression of criminal activity by providing timely and accurate analysis of criminal information to law enforcement agencies within Hennepin County.  CISA delivers products that improve public safety and increase officer safety through information sharing and analysis.
CISA collects crime reports and information from numerous city, county, state, and federal law enforcement agencies.  Reports and information are then analyzed in order to identify trends, provide investigative leads, help direct enforcement efforts, present hypotheses about who committed a crime or how it was committed, predict future crime patterns, and assess threats facing a jurisdiction.
Currently, bulletins and information are distributed to approximately 80 law enforcement agencies, including all local enforcement agencies in Hennepin County and various Municipal and County Sheriff’s Offices in Anoka, Carver, Dakota, Ramsey, Scott, Sherburne, Washington and Wright counties. Each enforcement agency can then further disseminate the information within their jurisdictions, if appropriate.
Analysts assigned to CISA have many job tasks, including monitoring and tracking crime trends on a countywide level.  CISA analysts also provide case support, link together charts, create time-lines, develop subject work-ups, and create maps.
Using GIS
Analysts using GIS mainly try to answer the question, “What crime is happening and where?”  Crime analysis once focused purely on the perpetrator and the victim, but did not take into account the location where the crime took place.  In the last few years, crime mapping has become more prevalent and uncovering patterns has become pertinent in solving crimes.
The analysts use GIS to produce many different types of maps, for example, maps that show the location of incidents, that identify hot spots where crime occurs, and that analyze the spatial relationship of targets and hot spots.  An analyst might also utilize the statistical capabilities provided in GIS software and other programs in an attempt to predict an offender’s next target, or areas where offenders might live, work, or retreat to after committing a crime.
Since CISA’s inception there have been numerous success stories.  CISA has been recognized for identifying numerous robbery and burglary trends involving several city and county law enforcement agencies.  CISA has also been successful in identifying multiple murder suspects.
