A resident of a senior living complex on the Arlington-Fairfax border stabbed a neighbor during an argument on March 10, and then committed suicide, Fairfax County police officials said.
POLICE FOUND Quinn Dieu, 71, dead in his apartment on the fourth floor of the Lockwood House, a facility for low-income seniors, said officer Bud Walker, a spokesman for Fairfax County police.
A 75-year-old man of Vietnamese ethnicity was found in his room on the same floor suffering from stab wounds to the upper body.
As of Monday afternoon the man was in critical but stable condition at Inova Fairfax Hospital, Walker said. Inova spokeswoman Erica Neufeld declined to provide further details about the individual.
Police officials are withholding his name because the hospitalized man is involved in the case. The victim has spoken with police investigators about the incident.
Just before 9:30 a.m. on March 10, Dieu and the victim began arguing in their native Vietnamese.
Police said Dieu produced either a knife or a sharp object and proceeded to stab the other resident. Police are not yet sure what caused the argument and violent attack.
Lockwood House employees discovered the attack while it was ongoing, and called the police. No other residents were involved.
By the time officers arrived at the scene, each individual was in their respective rooms.
"We are still investigating whether it happened in the hallway or rooms," Walker said. "We're still trying to draw a timeline as to where each event occurred."
DETECTIVES discovered several sharp objects and knives in both men's rooms and are still trying to discern the exact weapon used.
Police have never received a call from the facility before, which is mere feet over the border from Arlington.
"This is something I am willing to characterize as unusual," Walker said. "We've had no reports of problems here before."
A representative at Lockwood House declined to comment on the attack. Lockwood and neighboring Elmwood House are affiliated with the Episcopal Diocese of Virginia.
The Fairfax Police Department does not anticipate charging the hospitalized man with any crime, Walker said.
