Alexandria police yesterday identified a woman found slain in an apartment in the Southern Towers high-rise complex on Seminary Road as the wife of a U.S. serviceman stationed in Korea.

The partially clad body of Phuong Campbell, 28, of 4511 Hazelton Drive, Dale City, was found at 7 p.m. Thursday by Alexandria police acting on a tip from Fairfax County authorities.

Alexandria police spokesman Mike Nicholson said yesterday that autopsy results determining the cause of death will not be made pulbic until Monday. Authorities charged Thomas Mullens, 18, of Strawbridge Court in Fairfax County with murder shortly after the body was found.

Nicholson said police have not determined a motive for the slaying or ascertained how and why Campbell came to be in the apartment. They refused to say to whom the apartment was rented.

Fairfax authorities were alerted to the case when a priest at Saint Anthony's Catholic Church on Glen Carlyn Road in Fairfax was approached by a distraught young man who told him "a lot of things didn't make much sense," Fairfax police spokesman Warren R. Carmichael said.

Based on statements Mullens made in conversation with the priest, Alexandria police were notifed, according to Carmichael.

Nicholson said Campbell worked as a waitress at Valle's Steak House in Springfield. Investigators said yesterday that Campbell knew her alleged assailant and that Mullens had previously worked at the same restaurant. Restaurant employes declined comment yesterday.

Campbell's husband, Herman, stationed with the U.S. Army in Korea, reportedly was returning to Virginia yesterday. Mullens is being held in the psychiatric ward of Alexandria Hospital. A date for a court hearing has not been set.
