Mark A. Fields, 24, of Tuscon, Arizona.

A man who traveled with a woman from Arizona to sexually abuse an underage girl in Richmond last year has pleaded guilty to one of the charges in a plea deal.

Rhiannon S. Kennedy, 19, and Mark A. Fields, 24, both of Tuscon, Arizona, were arrested on June 7, 2020, by the Richmond Police Department.

Prosecutors said Fields engaged in an online relationship with a minor, who resided in Richmond.

A criminal complaint filed in McHenry County court alleged that Fields and Kennedy both traveled to Illinois to meet the girl and took her to a motel.

Fields allegedly sexually penetrated the victim, who was between 13-15 years old at the time, and Kennedy penetrated the girl with her fingers, the complaint said.

Fields was charged with aggravated criminal sexual abuse, indecent solicitation of a child, indecent solicitation of an adult, solicitation to meet a child and traveling to meet a minor.

On Tuesday, Fields entered a blind guilty plea deal with the McHenry County State’s Attorney’s Office.

Fields remains held in the McHenry County Jail without bond and Kennedy, who was out on bond, has an active warrant for her arrest.

A sentencing hearing for Fields is scheduled to take place on July 22.

The case was investigated by members of the Richmond Police Department and the McHenry County Sheriff’s Office. The case was prosecuted by Brian Miller of the McHenry County State’s Attorney’s Office.
