The victim who police say was killed by his roommate Friday has been identified as Andy Lun Yun, 32.
He was apparently struck with a blunt object inside their Franconia townhouse, Fairfax County Police say.
Yun's roommate, Eric C. Kweder, 34, has been charged with murder.
Police used a helicopter, K-9s and bloodhounds to search for Kweder in the densely wooded areas surrounding Yun and Kweder's housing development Friday. Kweder was arrested four hours later about five miles away.
Police confirmed that a call for help was placed at 10:15 a.m. Friday from inside the men's home at 6035 Hydrangea Drive.
