A Rutherford County grand jury will hear the case against the Smyrna mother charged in the deaths of her two young children earlier this month.
Samantha Harper appeared before a judge Thursday afternoon and waived her right to a preliminary hearing.
She remains behind bars on two counts of especially aggravated child abuse.
Smyrna police responded to Harper's home on Old Nashville Highway on August 2 and found Harper's two children, three-year-old Daniel Marise and two-year-old Savanna Marise, lying in the driveway near a parked car.
Authorities believe the children were trapped inside the car and possibly suffered a heat stroke before being removed.
Harper told police she put the children in her car and went back into her home and fell asleep.
She called 911 from a neighbor's home after discovering the kids.
Police also found Harper's home in deplorable conditions. The home was condemned just hours later.
The medical examiner has not released the exact cause of the children's deaths.
