The short answer is: it depends, although expungement may be an option.
That is, in Illinois, when records are “expunged,” they are either physically destroyed or
returned to the petitioner, with references to the underlying arrest and incident removed
from public record. The law that explains the availability of this process is the Illinois
Criminal Identification Act, which is a state statute identified as “20 ILCS 2630/5.2.”
If a person is arrested but the resulting criminal case is later dismissed, it is possible
that the “mug shot”—and all other records that are created by law enforcement
agencies and relating to the incident—may be expunged. This may also be an option if
there is no actual charge filed following the arrest, if the person is acquitted of charges,
if a conviction is vacated or overturned after an appeal, or if the person is found guilty
but successfully completes a term of “supervision” or certain types of probation. [Please
excuse the number of qualifying terms, like “may” and “certain types,” used in this
answer, as the circumstances in which expungement is available are very case
In some instances an expungement may be an option immediately after a case is
dismissed; in others, it may be available after a certain period of time, or not at all. To
obtain an expungement, a petition must be filed in court. If one is granted, a judge
enters an order directing the arresting agency and any other relevant agency to
expunge the relevant records (such as a mug shot).
You are encouraged to seek the help of a private lawyer in seeking an expungement.
Otherwise, for more information you may contact the Clerk of the 19th Judicial Circuit; in
Lake County, the Circuit Clerk is the entity with which a petition for expungement may
be filed. This office can be reached at 847-377-3600.
