The Investigative Unit is responsible for the follow-up investigation of all the crimes that reach beyond the scope of the patrol personnel. This includes crimes like burglaries, thefts, assaults, robberies, sexual assaults, narcotics investigations and homicides.
The most basic police functions are the protection of lives and property and the maintenance of the peace. Officers assigned to the Patrol Division carry out the bulk of this function. However, there are often times when follow-up investigation is needed after the patrol officers complete their work. This can be due to the lack of available time and resources, difficulty in locating people that need to be interviewed or the need for specialized evidence collection and investigative resources. In these cases, Detectives continue where the patrol investigation left off and attempt to uncover the facts and circumstances surrounding the incident.
Detectives work on both criminal cases and non-criminal cases. Criminal cases are incidents where violations of laws and/or ordinances have occurred. Non-criminal cases include such things as death investigations (e.g. suicides, accidents, etc.) and missing persons cases. The purpose of these investigations is to not only ensure that criminal acts did not occur but also to gain the necessary understanding of the incident for families and other concerned parties.
Detectives are also tasked with using their resources to do background checks for a wide variety of functions including liquor license applicants, applicants for peddler’s licenses and prospective tenants in the Pekin Housing Authority.
All of the Detectives for the Pekin Police Department receive specialized training in interview and interrogation, death investigation, crime scene technology, crime scene photography, evidence collection and a variety of other specialized areas. Investigators are available 24 hours a day, seven days a week for instances when their resources are needed immediately.
Detectives must also maintain a close working relationship with prosecutors at the State’s Attorney Office, probation and parole officers, caseworkers with Department of Children and Family Services, and with investigators of other area police departments.
Multi-jurisdictional crime is very common and regular meetings are held between departments to address these issues.
