Authorities say the foster mother of a 9-month-old boy who died when she taped a pacifier to his mouth faces charges.

Investigators say neonatal nurse Angela Dukes was in her first day caring for the boy on Feb. 8. They say she tried to quiet him but the taped pacifier blocked his breathing and he died that day.

State Law Enforcement Division spokeswoman Jennifer Timmons says the 30-year-old Dukes of Columbia was charged Wednesday with felony unlawful conduct toward a child.

Officials say Dukes is in the Richland County jail awaiting a bond hearing. It wasn't immediately clear if she had an attorney.

A woman identifying herself as Dukes' mother said she didn't want to talk about the arrest.
