A McHenry County sheriff’s detective, who since has resigned, has been charged with official misconduct and soliciting a sexual act. Officials said they were “deeply disturbed and disappointed.”

The McHenry County Sheriff’s Office administration was notified on September 16 of an off-duty incident involving Detective Christopher Marvel, 39, of Poplar Grove.

Marvel was immediately placed on administrative leave as a result, according to the sheriff’s office.

The agency opened an internal investigation in accordance with their department policy.

Marvel resigned on December 21 before the internal investigation was completed.

The Illinois Training and Standards Board was notified of his resignation in accordance with the SAFE-T Act, the sheriff’s office said.

The Illinois State Police and McHenry County State’s Attorney’s Office investigated and reviewed the case.

Marvel was charged on February 15 with eight counts of official misconduct, two counts of solicitation of a sexual act and one count of defrauding a drug or alcohol screening.

The sheriff’s office said in a statement released Tuesday that they were “deeply disturbed and disappointed” in Marvel’s actions.

“The Sheriff’s Office holds each of its employees to a high standard of expectations. Each personnel matter is investigated on a case-by-case basis to ensure we continue to provide professional services to the community,” the statement said.

“While Marvel failed to rise to the level of expectations we have set forth, we want to also remind our community that we have a dedicated team of deputies who do continually serve the community, promoting safety and equal protection for all,” the statement added.

The sheriff’s office directed all questions on the matter to the Illinois State Police and McHenry County State’s Attorney’s Office.

The Illinois State Police declined to release any information on the case.

Sources told Lake and McHenry County Scanner that Marvel was taken into custody and processed on the charges on February 16, the day after the case was filed.

He was released from the McHenry County Jail as the charges against him are non-detainable.

The exact nature of the allegations against Marvel was unclear. The felony court case is not listed in court records, indicating it had been impounded from the public by a judge.

The McHenry County Circuit Clerk’s Office confirmed there was “no public information” available for viewing on the case.
