Two defendants in unrelated Southeast Arkansas murder cases have separately filed notices of mental defect.

Kathy Livingston, a 58-year-old Lake Village woman who is charged with capital murder in connection the June 2011 shooting death of her husband, and Robert Carter Jr., a 23-year-old Lake Village man charged with two counts of capital murder in the April 2011 deaths of his two children, have both filed notices of mental defect.

Kathy Livingston is alleged to have fatally shot her 58-year-old husband Bobby Livingston on June 18 before shooting herself.

Bobby Livingston, president of Livingston Pecan and Metal, Inc. died at 6:30 p.m. on June 18 of a gunshot wound to the chest. Kathy Livingston survived a self-inflicted gunshot wound to the chest.

Robert Carter Jr. is accused of driving a vehicle into the yard of a Dermott residence on Iowa Street where Latasha Figures, Carter’s former girlfriend, and their two children lived.

As Carter drove into the yard on April 17, he is alleged to have struck and killed 18-month-old Amoni Elasia Carter and critically injured 4-year-old Nekole Carter, who later died at a Little Rock hospital. Figures, 24, was also injured.

Proceedings in both the Livingston case and the Carter case are suspended pending receipt of metal evaluation.

Carter’s attorneys have also asked for a hearing on a motion that the defense be allowed to be present at Carter’s state mental examination. Tenth Judicial District Prosecutor Thomas Deen is opposing the motion because he believes their presence could be disruptive of the examination.
