A 22-year-old Wisconsin woman faces three felony charges after police say she sold dog food as heroin and aspirin as a painkiller to an informant.

Megan Meyer of Plymouth is charged with two counts of imitation of a controlled substance and one count of bail jumping. She could face up to 12 years in prison because she was on probation at the time of her arrest.

A criminal complaint says Sheboygan County Sheriff's Department investigators discovered the fake drugs after a confidential informant purchased them during a controlled buy in November.

Initial testing was inconclusive. The criminal complaint says Meyer eventually confessed to selling the informant crushed dog food as heroin and an aspirin tablet as Percocet.

Court documents don't list an attorney for Meyer, who's due in court Wednesday.
