On the evening of June 6, 1995, a three-story house on South Fillmore Street in South Arlington was the scene of the county’s first recorded triple homicide. Three residents were found shot to death: homeowner William Miller, 52, a statistician for the Department of Labor; tenant David Stuart Kaplan, 34, an editor at Congressional Quarterly; and tenant Florence Marie Marks, 54, an accounting assistant for the Arlington government. The neighborhood described as quiet and well kept was shaken by the violence.

Investigators focused on 20-year-old Christopher J. Beck, a cousin of Marks who had once been taken in by Marks and Miller. Disputes including accusations of theft and an argument over a damaged bicycle reportedly soured their relationship, and prosecutors said Beck harbored resentment. Miller’s stolen car was recovered in Philadelphia with several guns inside; Beck was returned to Arlington, pleaded guilty to capital murder and related charges in May 1996, and was sentenced in August 1996.

Does anyone have memories of the South Fillmore Street neighborhood or details about the victims’ lives that could add context to this case?
