Soldier Charged With Murder in Fort Knox Shooting A soldier apprehended Thursday in Tennessee was charged with murder in the shooting death of a civilian employee at Kentucky's Fort Knox a day earlier. The FBI said in a court filing that Marquinta E. Jacobs fired a .45-caliber handgun at the victim, "striking him several times." Jacobs is charged with murder, according to the criminal complaint. Jacobs is the soldier whom Army investigators said was apprehended Thursday in Portland, Tenn., FBI spokeswoman Mary Trotman said. Army investigators had said a soldier wanted for questioning in the killing was apprehended in Portland, where Jacobs' mother lives. But the Army declined to identify the soldier, except to say he is a member of Fort Knox's 3rd Brigade Combat Team, 1st Infantry Division. The shooting occurred around 5:40 p.m. Wednesday in the parking lot at the Army Human Resources Command building, prompting a brief lockdown at the Army post in central Kentucky, about an hour southwest of Louisville. The victim was an employee of the command, which handles personnel actions for soldiers. This Aug. 18, 2010 image provided by the U.S. Army shows the Chaffee Gate entrance to Fort Knox. An Army civilian employee was shot and killed in a parking lot at Kentucky's Fort Knox on Wednesday, and investigators were seeking to question a man in connection with the shooting, authorities said. Army officials said in a news release late Wednesday April 3, 2013 that the victim was an employee of the U.S. Army Human Resources Command, which handles personnel actions for soldiers. The shooting occurred in a lot outside the command. The victim was transported to the Ireland Army Community Hospital where he was pronounced dead.

Investigators found eight shell casings at the scene. Investigators interviewed Jacobs' wife, who said he owned a .45-caliber Glock pistol, and they found ammunition at the home that matches the kind used at the crime scene. Jacobs' wife told police that Jacobs had left the home on a black motorcycle. The motorcycle was found at the home of Jacobs' mother in Portland. His mother told police he had left around 9 p.m. Wednesday driving a Kia Rondo. Police in Portland referred questions to the Army Criminal Investigation Command on Thursday. A message left for a spokesman at Army CID was not immediately returned Thursday night. Fort Knox has said in a statement that the soldier was a man believed to be traveling on a motorcycle. After the shooting, the victim was transported to the Ireland Army Community Hospital, where he was pronounced dead Wednesday. Chris Grey, a spokesman for the Army Criminal Investigation Command, said the shooting was a personal incident. "Special Agents from the U.S. Army Criminal Investigation Command are continuing the investigation and as previously released the shooting appears to be a domestic issue and not a random act of violence," Grey said in a statement. The identity of the victim was being withheld pending notification of family. AP writer Beth Campbell contributed to this report from Louisville
