PEORIA, Ill. (WMBD) — A 42-year-old Pekin man was sentenced last week to 10 years in federal prison for trying to entice a minor for sexual purposes. Mark Steven Peterson, 42, was sentenced on June 18 by U.S. District Judge Jonathan Hawley, who also ordered him to register as a sex offender. According to an affidavit contained in the initial charge, Peterson initiated contact through a social media platform with an individual whom he believed was the stepfather of a 10-year-old girl.
