Brian Witte Patients and colleagues are remembering Dr. Cerina Fairfax as a devoted mother, a caring dentist and the rock at the center of her family, after police say she was killed by her estranged husband, former Virginia Lt. Gov. Justin Fairfax. Police found both dead in their home in the Washington, D.C., suburb of Annandale, Va., early Thursday. They believe Justin Fairfax fatally shot his wife and then killed himself.
