APISON, Tenn. (AP) — A grand jury will decide whether or not to indict an Apison mother on charges after authorities say her 3-year-old son accidentally shot himself to death in a vehicle.

Local media outlets report 26-year-old Kelly Pittman waived her right to a preliminary hearing Monday in Hamilton County court. She also had her bond reduced from $500,000 to $2,000.

Pittman faces charges of child endangerment and criminally negligent homicide in connection with Gavin Pittman's death.

Investigators say the child died last month after accidentally shooting himself with a loaded pistol that he found in the unlocked glovebox of the family's minivan.

Kelly Pittman's attorney Dan Ripper says once his client is released from jail, she will focus on regaining custody of her other two children who are now in foster care.
