Police charged Man Ha Park, 53, of 13836 Braddock Springs Road with murder in the incident. The dead woman’s sister, 52, and Park were taken to Inova Fairfax Hospital with life-threatening injuries also described as stab wounds, police said.
Police said they responded to reports of a disturbance about 5:30 a.m. They did not detail the incident, but said it appeared to be “domestic in nature.”
It was unclear whether the man stabbed himself or was stabbed, according to Officer Lucy Caldwell, a police spokeswoman.
Several residents of the apartment community, a well-maintained complex across the street from the Spa World Resort Korean bathhouse, said they awoke just after 5 a.m. to the sound of a man and woman arguing.
The argument ended after a few minutes and was followed by a loud thud, said Lisa Cope of Alexandria, who said she was staying with a friend two floors down from the apartment where the incident took place.
Neighbor Jackie Wilmot, 50, said the woman who was killed lived in the apartment. The man was in a relationship with the sister, Wilmot said, and had come looking for her earlier in the morning, knocking on several doors.
Further information about the dead woman and her sister was being withheld pending notification of family members, police said.
“She was a good woman,” Wilmot said of her late neighbor. “A nice woman.”
Many other residents of the complex had left for work before the incident and didn’t know what had happened until they arrived home in the afternoon to find their parking lot cordoned off by police tape.
“I don’t feel like it changes the safety at all,” said resident Adam Sehab, 24, who had left for his job with the Department of Defense by the time police arrived.
“It’s scary,” Wilmot, a local schoolteacher, said. “This is a quiet place.”
The slaying is the fifth homicide in Fairfax County this year.
