According to court documents, the woman worked at Durbin's, a pizza restaurant in downtown Tinley Park. After finishing her shift, she went to JW Hollstein's, where she ordered a drink. She told investigators that was the last thing she remembered before waking up the next morning in her car, partially clothed, according to court records.

Investigators said forensic testing found Lee's DNA on the woman's clothing.

Tinley Park detectives investigated the case and presented evidence to the Cook County State's Attorney's Office Felony Review Unit, which approved the felony charge, police said.

What's next:

Illinois State Police said Lee has been employed by the agency since January 2004 and has been placed on administrative leave without pay.

Lee is scheduled to appear in court Tuesday. Illinois State Police said it is also conducting an internal investigation.
