The couple were shot in cold blood in their front yard just before 9:30 a.m., Fairfax County police said.
“They did nothing wrong. They were tragically and horribly murdered in their neighborhood,” Fairfax County police Maj. Ed O’Carroll said at an evening news conference.
O’Carroll identified the victims as Edward McDaniel Jr., 55, and Brenda McDaniel, 63. Both were military physicians, he said.
Edward McDaniel was an active Army colonel, FOX 5 of Washington D.C. reported.
Police had yet to identify the suspect — or suspects — who they believe killed the couple. Investigators were searching for a 2018 light-colored Nissan Altima with Maryland plate number 1EF1479.
