When do police fingerprint suspects?
Most offenders, except those accused of minor and traffic offenses, are fingerprinted as part of the booking process. Law enforcement agencies forward those fingerprints and other information to the Illinois State Police. The state police use the fingerprints and information pertaining to the arrest to update an offender's criminal history record or start 1 for someone with no previous record.

The reporting of the arrest triggers the creation of a new part of that person's criminal history record (or rap sheet), which will track that particular case. Today, many agencies are adopting an electronic fingerprints system called Live Scan.
