Man killed in police shooting identified A man shot and killed by a Fairfax County police officer during a standoff in Springfield on Thursday has been identified as 46-year-old John Geer, authorities said. Officers were called to a domestic dispute in the 7900 block of Pebble Brook Court about 2:40 p.m. Thursday, police said. The caller said a man in the house was armed with a firearm. As the man stood at his front door, officers negotiated with him for about 50 minutes to try to get him to come out, police said. During the negotiations, a patrol officer fired a single shot that struck the man, police said. Police did not immediately say whether the man was armed at the time or what prompted the officer to open fire. They also did not say whether anyone else was in the house during the incident. Following the shooting, the man barricaded himself inside the house, police said. About 4:30 p.m., officers used a hostage-rescue vehicle to gain entry to the front door of the house and render the man aid. Once inside, officers found the man dead, police said. An amateur video of the encounter obtained by WRC-TV shows the man standing in the doorway of the house with a storm door cracked. An officer appears to be pointing his weapon at the man from the front yard of the house, while a second crouches behind a tree with a police dog. It's unclear from the video whether the man was armed. Police said the officer involved in the shooting, as routine, has been placed on administrative leave while the investigation continues.
