The mother of two children who drowned four years ago has plead guilty to involuntary manslaughter and unlawful neglect in connection with their deaths. 

Sandy Emery's trial was set to begin this week, but WSPA reports that Emery entered a guilty plea yesterday. 

First responders were called after two-year-old Lacie Emery was found in a pool in September 2008.

While attempts to revive Lacie were undertaken, it was discovered that her brother, three-year-old Carter Emery was missing. He was discovered at the bottom of the pool. 

Both children were rushed to an area hospital, but pronounced dead. 

After an investigation by the Pickens County Sheriff's Office, the Pickens County Coroner's Office and SLED, Emery was arrested. 

Sandy Emery faces up to 15 years in prison. Sentencing will be held at a later date.
