A 34-year-old man in Milwaukee has been arrested after he was allegedly caught putting super glue in the soda of one of his coworker’s at the Wisconsin State Fair grounds.

Joseph R. Ross was taken into custody last week and charged with one felony count of placing foreign objects in edibles, court records reviewed by Law&Crime show. According to a probable cause affidavit, officers with the Wisconsin State Fair Park Police at about 11 a.m. on March 20 were conducting a foot patrol when an individual referred to in the document as “JH” made contact with them and requested a private conversation.

“During the conversation, JH told the Officers that approximately 2 to 3 weeks ago, JH suspected that her beverages on her desk had been contaminated by a chemical substance,” the affidavit states. “JH was made aware of the contamination, due to the strong chemical smell and taste. JH stated that upon consumption of those beverages, she became ill. Moreover, JH did not consent to anyone placing anything in her drink.”

Due to those events, JH said she set up a surveillance camera at her desk earlier that morning to see if anyone was putting something in her drink.

“At approximately 9:52 a.m., JH’s camera captured JH’s co-worker, whom JH shares an office with, Joseph R. Ross, hereinafter the Defendant, put a foreign substance into JH’s soft drink,” police wrote. “JH shared the video footage with the Officers.”
