RUSHVILLE, Ill. (AP) — A central Illinois woman has been charged with using an unidentified substance to spike the sports drink of an Illinois State Police trooper.

Authorities say 45-year-old Valeria Martinez and Kevin Weinmann, both of Beardstown, were stopped Tuesday along U.S. 67 in Schuyler County for suspected criminal activity. Troopers separated the pair as an investigation continued and it was later discovered a substance was placed in a trooper’s sports-drink bottle.

State police Trooper Mindy Carroll says the trooper drank what was in the bottle. The unidentified, affected trooper is recovering and stable. Additional information, including if the trooper was hospitalized, wasn’t revealed.

In addition to unlawful methamphetamine delivery and battery charges, Martinez is charged with possession of cannabis. Her bond was set at $250,000. The 27-year-old Weinmann of Beardstown is charged with unlawful possession of methamphetamine and intent to deliver, with bond set at $100,000.

Both were being held Thursday in the Schuyler County Jail. It isn’t known if either have legal representation.
