Emergency crews were called to the home by two of the girl's female relatives around 7 p.m. on Monday when she came running down the stairs with her clothes on fire. They extinguished the flames, but the girl was still hurt, suffering third-degree burns on 18-percent of her body.
Police say Herrera was upset that the girl interrupted him while he was listening to music. According to police, he sprayed her with lighter fluid and then lit her on fire.
Herra, who fled the home when authorities were called, was later found by relatives and brought back to the scene.
The girl remains at Loyola University Medical Center.
Aurora Fire Department Arson Investigators, the Kane County Child Advocacy Center, and the Department of Children and Family Services are investigating.
