The Crime Analysis Unit (CAU) possesses a vision of
innovation in analytics, supporting actionable and systematic crime responses.
The mission of the CAU is as follows:
- To be the premier CAU through the obtainment and processing of data from various internal and external sources, conducting thorough and appropriate analyses;
- Disseminate actionable intelligence in a timely and efficient manner; and
- Formulate best practice recommendations regarding crime and disorder to Jacksonville Sheriff’s Office (JSO) administration, operational personnel, as well as other local, state, and/or federal agencies.
After hour callouts through a Police Emergency Communications Officer (PECO) can be made in exigent circumstances by a
lieutenant or higher authority.

Crime Analysis Factors
- CAU analyzes data by various factors including type of crime, geography, date, time, watch, day of week, seasonal trends, suspects, victims, modus operandi, and vehicles, etc.
- Geographic factors can be analyzed by zones, sectors, subsectors, traffic analysis zone (TAZ), streets, and addresses.
- Temporal factors can be analyzed by year, season, quarters, months, weeks, days, watches, hours, or other breakout as requested.
- Data is examined to determine possible targets and/or victims.
- Suspect descriptors are combined with various crimes, FIR’s, calls for service (CFS), and other data to obtain the best, complete suspect information.
- Vehicle data from Incident Reports, FIR’s, CFS, and Traffic Crash Reports and download is maintained and analyzed.
- Modus operandi factors such as suspect’s actions, pretexts, threats, victim’s and suspect’s locations, points/means of entry and exit, tools used, and other elements are analyzed as shared information.
Information compiled in CAU is highly sensitive in nature and therefore shall not be disseminated to
non-law enforcement personnel. Any information to be disseminated to non-criminal justice entities is to be reviewed by the Public Safety Analyst Supervisor and/or the CAU Manager.
Reports generated as part of a public records request will be
disseminated to the Records & ID Unit and adhere to laws concerning police open data.
