Johnson's once-promising legal career ended after his guilty plea in 2000 to two counts of aggravated criminal sexual abuse in Kane County in exchange for a sentence of 30 months of probation. He admitted having sexual contact with two girls — one a teenager, the other younger than 13. After 10 years in the Cook County state's attorney's office, he was fired earlier in 2000 and agreed the following year to surrender his law license as he faced possible disbarment. Now 51, he is listed on the state sex offender registry.
