COLUMBIA — Autopsies are being done on two children authorities say were shot and killed by their mother at the family’s Pickens County home.

Coroner Kandy Kelley says examinations will be done Wednesday on 7-year-old Carly Simpson and her 5-year-old brother, Sawyer.

Both bodies were found Tuesday in their beds. Their father, Michael Simpson, was also shot and has been hospitalized with life-threatening injuries.

Sheriff Rick Clark says Suzanna Simpson was found in a wrecked pickup truck outside the family’s home early Tuesday. Authorities say the 35-year-old mother told a nurse she shot her family and had wanted to kill herself.

Simpson has been charged with two counts of murder and attempted murder and is hospitalized. It wasn’t known if she had a lawyer or when she would appear in court.
