Samuel Perry, 18, pleaded guilty Monday to murder, kidnapping, larceny and two counts of robbery of Goldstar Taxi Services driver Jack L. Horne Jr., said Fort Benning spokeswoman Elsie Jackson. Col. James Pohl presided over the court-martial.
Perry was linked to the killing in an FBI affidavit he gave to officers after his arrest. He admitted participating in the robbery and killing of Horne with two other men: Mastermichael Ramsey, 25, and Travis Jahcorick Livingston, 24.
"The soldier said that he, Ramsey and Livingston all shot Horne," FBI Special Agent Todd Kalish wrote in an affidavit.
In his last radio report to the cab company, Horne, 55, told dispatchers he was on his way downtown. He was never heard from again. His cab was found the following day at an apartment complex in nearby Phenix City, Ala.
Ramsey and Livingston later led investigators to Horne's body, which was about 20 feet off an unmarked road in the woods on the military base.
Perry's case was removed from civilian courts to a military setting, but the cases of Ramsey and Livingston remain in U.S. District Court.
The two men have been in custody since August 2006. Perry will be transferred to Fort Leavenworth, Kan., Jackson said.
