Adult Investigation Unit

AIU continues the investigations initiated by the Patrol Division or by assignment from the Chief’s office. The unit is staffed with one Lieutenant, 4 Sergeants, and 13 Detectives. These investigations include responding to crime scenes, conducting interviews of all parties involved and obtaining and executing search and/or arrest warrants. Investigators have the responsibility to sort out the facts of a crime and establish probable cause to support the arrest and conviction of the offender. Investigators prepare criminal case files to ensure proper charges are filed and assist at trial when needed.
