Fort Carson Sgt. Vincinte Jackson is charged with murder and premeditated murder. He's accused in the January death of Spc. Brandy Fonteneaux, of Houston.
After closing arguments, the case goes to a military panel similar to a jury in a civilian case. Vincinte blames the slaying on a potent mixture of anti-depressants and alcohol.
He was led into the court martial Thursday morning wearing a green military uniform with his ankles and wrists shackled.
