People v. Harding 

Defendant was convicted of child abduction for twice pulling up to nine-year old girls in his van, and offering them a ride, though girls did not accept ride and were not actually abducted by Defendant. Evidence admitted at trial of Defendant's prior convictions of attempted aggravated criminal sexual assault of adult women, which prosecution stated was to show his propensity to commit sex crimes. Section 8-5 of Criminal Code prohibits only a combination of convictions, rather than prosecutions, for inchoate and principal offense. Evidence of prior sexual assault convictions improper as it served only to demonstrate his general propensity to commit crime, as court must examine relevance of prior convictions to crimes charged, and propriety of evidence is not determined by prosecution's statement of its purpose.
