The Division of Criminal Investigation (DCI) was created in 1921 to provide investigative support and expertise to law enforcement agencies across the state. The division is comprised of four functional areas:
There are 123 sworn officers and 102 civilian employees handling the ever-increasing workload of the DCI. |

Automated Fingerprint Identification System (AFIS) | |
As of June 30, 2003, the Automated Fingerprint Identification System (AFIS) included over 467,352 ten print cards and nearly 19,826 latent prints. AFIS is available to all criminal justice agencies throughout Iowa for use in criminal investigations. During Fiscal Year 2003, 20,826 ten print "hits", and 351 latent print "hits" were made via AFIS. A ten print card is a card usually 8" X 8" which has a permanent set of an individual's fingerprints on it. There are 10 individual blocks, one for each of the fingers and they are numbered 1 through 10, starting with the right thumb and concluding with the left little finger. These are the "rolled impressions" and each finger must be rolled from one side of the fingernail to the other side of the fingernail. Below the 10 blocks there are blocks for printing each hand with two blocks in the middle for printing the thumbs. These are called "plain impressions" and are used to make sure that the sequence of the fingers were printed correctly in the rolled impressions. Above the fingerprint blocks are spaces for the descriptive data of the individual, such as name, sex, race, height, weight, date of birth, place of |

birth, social security number, arresting agency, reason for arrest, etc. There are two types of ten-print cards, one is criminal which is used when an arrest is made, and the other is civil which is used for anything other than criminal. A
hit occurs when a print lifted from a crime scene matches one in AFIS.
Livescan
sites were introduced in Fiscal Year 1999. Livescan is a method of sending
required arrest fingerprint cards electronically from a police agency
to the central site at DCI. Agencies are required to take two sets of
prints and mail two (one to DCI and one to the FBI). With livescan, they
roll one set and print as many as needed. The addition of livescan terminals
at various locations around the state has helped expedite the process
of creating and updating criminal history information maintained by the
Division. |

The Criminalistics Laboratory sections consist of:

|
The criminalists analyze human biological fluids for OWI enforcement and most street drugs seized by law enforcement agencies in Iowa. The number of cases involving the identification of street drugs analyzed by the laboratory in Fiscal Year 2003 was 6,565. |
DCI
Crime Laboratory |
Overall, the Criminalistics Laboratory processed over 22,226 cases. The identification of controlled substances, analysis of human biological fluids for OWI investigations and latent print identification represent the largest volume in the caseload duties for the laboratory. |

DNA |
Throughout the year the laboratory continued DNA analysis on both active casework as well as the convicted offender specimen database. The laboratory completed analysis of 622 DNA related cases. The Convicted Offender database currently consists of 3,541 profiles which are available for searching on a national basis since participation in CODIS (COmbined DNA Index System) was finalized. The DNA Section examines biological materials such as blood, semen and saliva. DNA profiles of these biological stains are developed using Short Tandem Repeat (STR) technology. The profiles are compared to the DNA profiles from standard samples from individuals who may have contributed the biological stains. Generally, biological stains are shown to be unique to one individual. DNA profiles may be entered into either the Forensic Casework database or the Convicted Offender database. The Forensic Casework database contains DNA profiles from crime scene evidence. The Convicted Offender database contains DNA profiles of individuals convicted of sex offenses and/or other violent crimes. These two databases make up the state component of the COmbined DNA Index System. CODIS enables federal, state, and local crime laboratories to exchange and compare DNA profiles electronically, thereby linking crimes to each other and to convicted offenders. Routine searches of casework-related profiles against both convicted offenders and forensic unknown databases at state and national levels has been instituted. |

General Criminal Investigations |
The 36 special agents assigned to the General Criminal area provide investigative expertise to local, county, and state agencies requesting assistance in major criminal cases. They provide expertise in the areas of crime scene searches, collection and preservation of evidence, investigations, and with suspect and witness interviews. The DCI works with all state, federal, county and city law enforcement agencies in the state to resolve crimes. Agents of the General Criminal Unit provide these services from 14 field offices situated within four geographical zones in the state. Two agents in the DCI are specifically trained to provide polygraph services for the Department, as well as the entire Iowa law enforcement community. |
