42 year old Mark Mull is accused of sexual assaulting an eight year old child over the past seven months. He is formally charged four counts of predatory criminal sexual assault, and one count of aggravated criminal sexual assault.
Mull is a paramedic with lifeline ambulance in Belvidere. The service is operated by OSF Saint Anthony. To become a paramedic he had to pass several state background checks. Mull had a clean criminal record in Boone County but because of these new charges OSF Saint Anthony has suspended mull.
Mull was arrested Friday. He's being held in the Boone County Jail on $100,000 bond.
