My question involves expungements or pardons for the state of: MI

If an 18 year old committed misdemeanor retail fraud, was given HYTA status and successfully completed it, paid all costs, has never committed any other crime, doesn't have a conviction on record, and has earned a college degree, would (or could) expungeent help make sure that no one ever sees the record? How would a HYTA misdemeanor (<$40 taken) affect his chances for entering a career in the criminal justice field?
