Police have identified a man killed in his Franconia home Friday as 32-year-old Andy Yu.

Officers found an ax next to Yu’s body when they were called to the scene Friday morning in the basement of a townhouse in the 6000 block of Hydrangea Drive, according to a search warrant. Yu suffered trauma to his head and neck, the warrant said.

A roommate called authorities after hearing Yu and another roommate, Eric C. Kweder, fighting, the search warrant said.

The roommate heard yelling and then sounds consistent with someone being struck, according to the search warrant.

Kweder, 34, a former All-Met athlete and Marine, was arrested in the killing Friday afternoon after a police search using a helicopter and dogs, Fairfax County police said.

Earlier, he had fled the scene of the killing, police said.

Police declined to discuss a motive for the slaying. Yu’s family could not be reached for comment.
