Clay County Sheriff Eddie Scott said the arrest stemmed from the death of her 2-month-old infant, Brinston Smith.
Scott said authorities were notified on Monday, April 7 by the Mississippi Crime Lab that the infant boy had died from a lethal dose of codeine and has been ruled a homicide.
Smith is currently in the Clay County Jail under no bond.
Scott said the case is being prepared for the grand jury and a formal indictment, if the evidence warrants it, will be issued as soon as possible.
The CCSO is being assisted in the investigation by the Mississippi Bureau of Investigations and the Clay County Coroner’s Office.
