An apparent domestic-related homicide occurred inside a Chantilly, Virginia home on Pennypacker Lane in the early morning of February 28, 2025. First responders arrived shortly after 6 a.m. after a 911 call from the residents’ daughter and found 87-year-old Marilyn Sommer with fatal gunshot wounds to her upper body; she was pronounced dead at the scene.

Marilyn’s husband, 88-year-old Douglas Sommer, was in the house when police arrived and was taken into custody. Their daughter, who had been inside the home and was unharmed, provided a witness account to detectives. Investigators say an argument over an impending move to an assisted living facility—which Douglas reportedly opposed—escalated and culminated in the shooting.

If anyone knew Marilyn or was in that neighborhood on February 28, 2025, please share information with the Fairfax County authorities. Could someone who knew the family or observed tensions around the move provide details that might help clarify what happened?
