Fairfax County police have arrested a man who they say killed an Annandale woman last week.

On Friday, Fugitive Unit detectives found and arrested Santo Ortez Sheffey, 49, on the 1500 block of Pennsylvania Avenue in Southeast D.C. Sheffey has no fixed address. He has been charged with the murder of Sharon Harvin. Harvin’s son found her stabbed to death in the kitchen of her home on the 6200 block of Indian Run Parkway on Sept. 2.

Police also found the victim’s 2006 Kia, which was missing from the crime scene, at the 2500 block of Shirlington Road in Arlington County.

Sheffey will stay in D.C. until he is extradited to Virginia. Police would not say why they suspect he is a candidate, adding that they do not comment on specific forensic evidence.
