Caledonia police say a 26-year-old man is charged with trying to roofie his girlfriend by putting prescription cough medicine in her soda.

Racine County Eye is not naming the man to protect the identity of the woman.

The Wauwatosa man was charged Friday in Racine County Circuit Court with one felony each of delivery of narcotics and placing foreign objects in edibles. If convicted, he faces up to 18-1/2 years in prison and/or up to $60,000 in fines.

According to the criminal complaint, the man and woman were at her house Thursday, and she was drinking a Diet Coke. She left her open soda can on a counter while she went to run and errand, leaving the man and her sleeping mother at home. When the woman returned, she took a sip of her Coke and noticed a funny cherry taste, so she opened another can to compare.

Police say the woman located a cherry-flavored cough syrup in her house and asked the man what he knew about it, but he just shrugged and said he didn’t know. The woman took the altered soda and the cough syrup to the Caledonia Police Department to file a complaint. A few hours later, she returned with the man in tow.

When the woman returned home from filing her initial complaint, she told the man she had reported the incident to police, and he said, “You’re going to hate me, but I did put a little something in your soda.” The woman told the man to return her keys and get out, the complaint reads, and he agreed to go to the police with her.

Officers say the man admitted to using a cough medicine in the woman’s soda prescribed for a child for whom she provides childcare. Police went to the woman’s home to recover the medicine and noted that it is a Schedule II opioid. The woman also reported that she is a diabetic and has to closely monitor her sugar intake and how medications may affect her; that after drinking the soda containing the cough syrup she felt a buzzing feeling.

The man was assigned a $2,000 signature bond and reported to undergo random drug testing and submit testing after each court date. He will next be in court March 10 for his preliminary hearing.
