(Reading, OH)--A 14-year-old boy is held on charges of Murder and Felonious Assault for the death of his two-month-old step-sister.

Police and medics were called June 25 to a house on East Vine on a report of a non-breather.  The child was taken to Jewish Hospital in Kenwood where she was later pronounced dead.

The girl's step-brother was arrested July 12 and booked into the juvenile detention center on Auburn Ave. 

Police said the boy told them that he heard voices in his head telling him to do it. Officers said the boy has a psychiatric disorder.
