Citing the money laundering article of the controlled substances act and drug asset forfeiture procedure, court filings through the office of Kane County State's Attorney Joe McMahon argue the money seized should be forfeited. The cash was furnished or intended to be furnished in exchange for an illegal substance, according to the complaint. Further, the state argues, the driver knew it represented "proceeds of unlawful activity," and transported it intending to promote the carrying on of illegal activity "from which the criminally derived money was obtained."
