The Florence County Sheriff's Office says Raquel Y. Coker, 27, was under the influence of drugs and alcohol when she put her 5-month-old baby girl in the bathtub and fell asleep.
The baby drowned, and now Coker is charged with Involuntary Manslaughter.
Deputies say it happened on April 17. Coker was booked into the Florence County Detention Center Thursday.
At Coker's bond hearing, Investigator Jennifer Floyd, with the Florence County Sheriff's Office, said, "We're here today because of a bad decision that turned deadly for the defendant's 5-and-a-half-month-old daughter this is a case of terrible judgement while she was under the influence of marijuana and alcohol."
Magistrate Judge Belinda Timmons set Coker's bond at $15,000. As a condition of her bond, Coker's not allowed to have any contact with the baby's paternal relatives.
Coker has a 3-year-old daughter. That child has been placed with Coker's parents, through the Department of Social Services.
