Criminal Investigation Division

Criminal Investigation Division

The Criminal Investigations Division (CID) is a multi-task orientated unit of highly trained and experienced criminal investigators.

The division’s core values are to Identify Crime, Solve Crime, and Obtain Convictions that enhances the quality of life for the citizens and visitors of Milwaukee County utilizing a data-driven crime reduction strategy.

The General Investigations Unit is responsible for investigation a variety of criminal activity such as violent crimes, warrant sweeps, weapon offenses, sexual assault, battery, drug arrests, sexual predators, sudden death, stolen vehicles, intimidation of witnesses, and graffiti / tagging.  The unit conducts special investigative cases for the County Executive, County Board of Supervisors, Milwaukee County Department Heads, citizen groups or investigations deemed special in nature by the Sheriff or his designee.  Confidentiality, professionalism, job knowledge and proper decorum are paramount in conducting these types of investigations, which are often sensitive and reflect directly on the Agency.  The unit also works closely with the other 18 municipal law enforcement agencies in the county providing primary and supplemental investigative services.    

The Computer Crimes Unit continues to meet the technical requirements and computer skills for investigating 21st century crimes, to include identity theft, child pornography / enticement, Credit Card Fraud, Check Forgery, and E-mail Harassment.  In addition, the unit has the ability to conduct forensic examinations on many electronic devices such as computers and cell phones.  

The Apprehension Unit is responsible for looking for persons who are wanted for various crimes.  Currently there are over 40,000 active warrants in Milwaukee County and many of those do not reach the level of violent crimes and therefore do not get the attention of the U.S. Marshal’s Fugitive Task Force.  The unit is assigned to work on the backlog of these warrants.  The unit actively searches for offenders of Surrender of Firearms Hearings (Injunction Hearings) of which Judges have issued Body Attachments.  The Unit works with the District Attorney’s Office to locate and gain compliance with court ordered DNA sample submissions.  The unit also searches for absconders from the House of Correction.     

The Background Investigative Unit is responsible to complete the background investigations of persons applying for positions within the Milwaukee County Sheriff’s Office and other positions with Milwaukee County.  This unit also completes background investigations for other government agencies county and statewide upon their request.

In addition, CID sworn personnel are assigned to full-time and part-time task force positions.  These task forces include the US Marshals Office, the High Intensity Drug Trafficking Area (HIDTA), the Alcoholic Tobacco and Firearms (ATF), the Federal Bureau of Investigations (F.B.I.) Joint Terrorist Task Force (JTTF), the Cyber Crimes Task Force (CCTF), the Department of Agriculture, and the State Internet Crimes Against Children Task Force (ICAC).

CID personnel must achieve and maintain a high degree of proficiency and expertise, and be versatile in numerous disciplines and types of investigations.  Detectives must maintain expert skills in interviewing, interrogation, surveillance, evidence preservation, and crime scene management.
