The Lake County Sheriff’s Office Detective Bureau is unique in that in addition to general duty cases, investigations of crimes that occur within the townships we patrol,   we handle a number of cases specific to a Sheriff’s Office:

  • Jail Investigations, assaults, conveyance of contraband, furlough violations etc..
  • Records requests, Jail and phone call records.
  • County Office Investigations
  • Warrant related service/investigations. (Note: At any time, the Sheriff’s Office holds about 900 to 1000 active arrest warrants)

In addition to the above, the Sheriff’s Office Detective Bureau handles all major internal affairs investigations, not only for the Sheriff’s Office but for all county office holders.

The Detective Bureau also conducts pre-employment CVSA exams for not only the Sheriff’s Office but also for other county agencies and police agencies. This past year 57 such exams were conducted.

       Our Detective Bureau also actively assist’s the Lake County Narcotics Agency with informant development and information sharing. Detectives also assist with manpower as needed on an operational basis. One would be remiss not to recognize the Lake County Jail as a source for the gathering of intelligence information / informant development in a pro-active manner. Members of the Detective Bureau stand at the ready to assist any Law Enforcement agencies in the furtherance of their investigation and/or prosecution by arranging/facilitating interviews with inmates or the copying of inmate jail calls, assistance in securing arrest/search warrants or conducting interviews for out of state agencies.
