An Eau Claire police officer dedicated to giving suspects lie detector tests is now under investigation for how he handled those exams.
The officer is on paid administrative leave pending completion of an investigation into polygraph examinations he conducted.
City human resources director Dale Peters says the officer's name won't be released until the internal investigation is completed, and the Eau Claire Police and Fire Commission determines whether discipline is warranted.
Peters says it's possible the investigation may not lead to any findings of misconduct.
Eau Claire Police Chief Jerry Matysik says they discovered irregularities in how polygraph examinations were conducted by a former examiner after a new one was named.
The chief says his department asked the state Justice Department's Division of Criminal Investigation to conduct an independent review.
