FORT CARSON, Colo. (December 13, 2012)—Army Sgt. Vincinte Jackson was found guilty of unpremeditated murder Thursday in the stabbing death of a fellow soldier at Fort Carson, Colo.
A military panel convicted Jackson after several hours of deliberation on Thursday.
The panel later sentenced him to life in prison with the possibility of parole.
Prosecutors didn't immediately know how many years Jackson would serve before he is eligible for parole.
Jackson's lawyers conceded that the sergeant killed Spc. Brandy Fonteneaux, 28, of Houston but argued that the slaying was so brutal and random that it couldn't have been premeditated.
They also said a combination of heavy drinking and a prescription antidepressant left Jackson unable to control his own actions.
Prosecutor Capt. Jason Quinn scoffed at that argument.
Quinn said Jackson made a conscious decision to leave his room and walk to Fonteneaux's, where he stood over her while she slept and then attacked her after she awoke.
She was stabbed more than 70 times.
Fonteneaux had been in the Army two years.
She was a food service specialist in the 4th Engineer
