COLUMBIA, S.C. (AP) -- A judge has granted a request by prosecutors to perform a mental evaluation on an Orangeburg County mother accused of suffocating her two young sons and driving her car into a river.

Court officials say Circuit Judge Edgar Dickson agreed Wednesday that a psychiatrist needs to figure out if 29-year-old Shaquan Duley is fit to stand trial.

Duley was charged with two counts of murder after divers pulled the bodies of 2-year-old Devean Duley and 18-month-old Ja'van Duley from the North Edisto River on Aug. 16.

Investigators said Duley confessed to smothering the boys after a fight with her own mother, who Duley said badgered her about her failures as a parent.

Duley is in jail and has been denied bond. No trial date has been set.
