On April 2, 2020, Heather Y. Zujkowski, a 36-year-old disabled Army veteran and mother of three, was shot and killed inside her home on Bennett Branch Road in Mount Airy, Maryland. Authorities say her estranged husband, 35-year-old Joseph Zujkowski, used a rifle in the attack. The couple had been separated and a protective order against Joseph had expired in January 2020. The three children were in the home during the shooting but were not physically harmed.

An 18-year-old neighbor, Noah Homayouni, was also shot and killed outside during the same incident; investigators said the motive for his killing was not immediately known. After the shootings Joseph Zujkowski left the scene and law enforcement contacted him by phone as he returned to Gaithersburg; a brief standoff occurred when police arrived and Joseph Zujkowski died of a self-inflicted gunshot wound. Heather had worked as a French linguist at Fort Meade and volunteered with several organizations. The community mobilized to support her children, who were left without their parents.

Did anyone in the Mount Airy or Gaithersburg area have observations about the days around April 2, 2020, that could help fill gaps in the timeline?
