An Army sergeant sought by police for questioning in the deaths of a woman and an infant whose bodies were found in his Baileys Crossroads apartment turned himself in at Fort Benning, Ga., Thursday and was charged yesterday with murder.

Staff Sgt. Terry L. Simmons, 27, had been listed as absent without leave from duty at the Pentagon since last Monday, the day after the badly decomposed bodies of the woman and child were found in a closet of the apartment at 3606 Barcroftview Ter.

Fairfax County police yesterday charged Simmons in the death of the woman tentatively identified as Caroline Yoo, 29, with whom Simmons had been living. Police said Yoo, who was honorably discharged from the Army in February because of pregnancy, had a 5-month-old daughter, Julie. Yoo apparently was strangled, police said.

County police spokesman Warren Carmichael said identification of the bodies was hampered by their condition and the female infant still has not been identified. When found after neighbors complained about an odor, the two had been dead "well over a week," Carmichael said.

Simmons had been on leave since Aug. 1 and was to have reported to the Pentagon last Monday, but called to say he would be late, according to an Army spokesman.

After Simmons was taken into custody by military police at Fort Benning on Thursday, he was interviewed by a Fairfax County police investigator, who Carmichael said was sent "as a logical extension of our investigation."

Fairfax prosecutor Robert F. Horan Jr. said no charges have been placed in connection with the infant's death because evidence is still being developed.

Virginia authorities are expected to attempt to extradite Simmons for trial in Yoo's death.
