A 19-year-old from Carpenterville was arrested by McHenry County authorities Tuesday and charged with trying to foil a drug test that was part of her probation, authorities said.
Sonia Rodriquez, of the 1900 block of Bristol Circle, was required to take three drug tests as a part of her probation from an arrest last summer on charges of misdemeanor drug paraphernalia possession and disorderly conduct, according to court records.
She now faces a felony punishable by up to three years in prison and was being held on $15,000 bail. Rodriquez is next due in court Friday.
McHenry County Undersheriff Andrew Zinke said probation department officials went into the drug screening area after Rodriquez was done and found a container, which authorities suspect she filled with her own "clean" urine well before the test.
"She brought her own container with her. They notified investigators, detectives interviewed her and subsequently charged her," Zinke said. "This happens probably more than you think. We probably get a dozen of these a year. She must have saved it for quite some time."
Rodriguez was arrested in July 2013 by McHenry County Sheriff's deputies and pleaded guilty in October, court records show. She received six months supervision, was fined $600, ordered to perform 30 hours of community service and complete the drug tests, records show.
