The function of the Criminal Investigations Division is to investigate all major felony crimes from the crime scene through the investigation and into court.
The Criminal Investigations Division is supervised by Chief of Detectives Dustin Christner and Det. Sgt. Andrew Pierson, and staffed by detectives who are assigned to various roles. Some of those roles include several general case felony detectives, one special victim’s detective, one evidence technician/crime scene processor, narcotics unit detectives, street crimes officers, two school resource officers (SRO), and one secretary. The majority of detectives are members of the Major Case Squad of Greater St. Louis.
Not all cases requiring follow-up investigation are referred to the Criminal Investigations Division. Many are retained in the Patrol Division. If you have reported a crime and it has been assigned to a detective, you will normally be contacted by the detective soon after the detective has been assigned to further investigate the case. If you wish to check on the progress of your case, and an investigator has not contacted you, you should check with the police officer who initially took your report.
GENERAL CASE DETECTIVES
Members selected for assignment to the Criminal Investigations Divisions as a general case detective are chosen for the knowledge, skills, and abilities they exhibited as patrol officers and for their strong work ethics and desires to succeed. These detectives receive extensive specialized training to help develop them into capable interviewers and investigators. They also receive specialized training in areas such as death investigations, crime scenes, fingerprinting, evidence handling, forensics, court presentations, surveillance, etc.
SPECIAL VICTIMS DETECTIVES
Special Victims detectives tend to focus their efforts on sex crimes, child pornography, child abuse/death cases, missing persons, crimes against the elderly, and juvenile runaways.
EVIDENCE TECHNICIAN / CRIME SCENE PROCESSING
The Alton Police Department Evidence Technician accepts, catalogs, safeguards, stores, produces as required for court, returns to a legal owner, or otherwise legally disposes of all property coming into the custody of the Alton Police Department.

Some of the duties of the evidence technician at crime scenes include photographing crime scenes and evidence, diagramming/sketching crime scenes, scene measurements, processing crime scenes for latent prints, taking a plaster cast or inked impressions of footprints, shoe prints, and tire tracks, collection of hairs and fibers for analysis, detection of blood, blood pattern interpretation, evidence collection, documentation of autopsy examinations, and collection of entomology samples.
The Evidence Technician receives assignments from the Chief of Detectives for major crime scenes and is subject to call out 24 hours a day, seven days a week. Some of those crime scenes include homicides, suicides, shootings, robbery, arson, sexual assault, etc.
