Former Olmsted jail deputy enters guilty pleas in local cases

(ABC 6 News) – A former Olmsted County deputy entered petitions to plead guilty to saving photos of undressed Rochester jail detainees, as well as placing hidden cameras in bathrooms to film women.

In exchange for his plea, Olmsted County will dismiss Mathew Adamson’s additional child pornography and public officer misconduct charges, as well as an entire child solicitation case which led to the discovery of Adamson’s extensive sex crimes.
