46-year-old Matthew Adamson was charged in both federal and state court after being accused of secretly recording 12 and 13-year-old girls multiple times from 2015 through 2023 in a changing room at the Olmsted County Adult Detention Center. 

Court documents say law enforcement discovered the videos after Adamson was charged in a child sex solicitation case in which Adamson was accused of attempting to solicit sex from an undercover Rochester police officer who was posing as a 13-year-old girl. 

Adamson was sentenced last month to almost 20 years in prison for his conviction on a federal charge of producing or attempting to produce child pornography.

The state charges against Adamson stemming from the child sex solicitation sting and subsequent child pornography discovery were filed in two separate cases.

Former Olmsted County, MN Detention Deputy Sentenced for State-Level Convictions

Olmsted County Court records indicate Adamson agreed to a plea deal with Olmsted County prosecutors involving the two local cases last month following his federal sentencing.

Adamson pleaded guilty to four gross misdemeanor counts of interference with privacy stemming from the video recordings in the county jail.

In exchange, the Olmsted County Attorney's Office dropped three felony child pornography charges and all of the charges against him in the child sex solicitation case.

On Tuesday Adamson was sentenced to 364 days in jail for the state-level conviction. He’s credited with 304 days spent behind bars and will serve the local sentence concurrently with his federal 235 month prison term.
