Authorities say an Ohio mother has been arrested on charges accusing her of injecting her teenage children with heroin before sending them to school.

The Hocking County Sheriff's Office says 35-five-year-old Shantel Parker, of Laurelville, was arrested Friday at Ohio State University hospital on warrants charging her with two counts each of felonious assault, corrupting another with drugs and endangering children.

Investigators say Parker has been providing heroin and other drugs to her children, ages 14 and 16, for several months.

The teens have been placed with the county children's services agency. Parker was to be jailed in Franklin County to await a hearing and transport to Hocking County. She was in custody and couldn't immediately comment.

The Logan Daily News reports Parker had studied nursing from 2008 to 2010.
