WASHINGTON – President Bush on Monday approved the execution of an Army private, the first time in over a half-century that a president has affirmed a death sentence for a member of the U.S. military.

With his signature from the Oval Office, Bush said yes to the military’s request to execute Ronald A. Gray, the White House confirmed. Gray had had been convicted in connection with a spree of four murders and eight rapes in the Fayetteville, N.C., area over eight months in the late 1980s while stationed at Fort Bragg.

“While approving a sentence of death for a member of our armed services is a serious and difficult decision for a commander in chief, the president believes the facts of this case leave no doubt that the sentence is just and warranted,” White House press secretary Dana Perino said.

In the military courts, “Private Gray was convicted of committing brutal crimes, including two murders, an attempted murder and three rapes. The victims included a civilian and two members of the Army. … The president’s thoughts and prayers are with the victims of these heinous crimes and their families and all others affected.”

Unlike in the civilian courts, a member of the U.S. armed forces cannot be executed until the president approves the death sentence.

Gray has been on death row at the U.S. Disciplinary Barracks at Fort Leavenworth, Kan., since April 1988.

Members of the U.S. military have been executed throughout history, but just 10 have been executed by presidential approval since 1951 when the Uniform Code of Military Justice, the military’s modern-day legal system, was enacted into law.

President Kennedy was the last president to stare down this life-or-death decision. On Feb. 12, 1962, Kennedy commuted the death sentence of Jimmie Henderson, a Navy seaman, to confinement for life.

President Eisenhower was the last president to approve a military execution. In 1957, he approved the execution of John Bennett, an Army private convicted of raping and attempting to kill an 11-year-old Austrian girl. He was hanged in 1961.

Gray was held responsible for the crimes committed between April 1986 and January 1987 in both the civilian and military justice systems.

In civilian courts in North Carolina, Gray pleaded guilty to two murders and five rapes and was sentenced to three consecutive and five concurrent life terms.

He then was tried by general court-martial at the Army’s Fort Bragg. In April 1988, the court-martial convicted Gray of two murders, an attempted murder and three rapes. He was unanimously sentenced to death.

The court-martial panel convicted Gray of:

-Raping and killing Army Pvt. Laura Lee Vickery-Clay of Fayetteville on Dec. 15, 1986. She was shot four times with a .22-caliber pistol that Gray confessed to stealing. She suffered blunt force trauma over much of her body.

-Raping and killing Kimberly Ann Ruggles, a civilian cab driver in Fayetteville. She was bound, gagged, stabbed repeatedly, and had bruises and lacerations on her face. Her body was found on the base.

-Raping, robbing and attempting to kill Army Pvt. Mary Ann Lang Nameth in her barracks at Fort Bragg on Jan. 3, 1987. She testified against Gray during the court-martial and identified him as her assailant. Gray raped her and stabbed her several times in the neck and side. Nameth suffered a laceration of the trachea and a collapsed or punctured lung.

The six-member court-martial panel returned its unanimous verdict after about two hours of deliberations.
