A woman was killed and set on fire Wednesday in the Seven Corners area of Fairfax County, Virginia, authorities say. Police have arrested a man in her murder.
Residents of The Villages at Falls Church building in the 2900 block of Willston Place said they heard a woman screaming for help and called 911 before 3 p.m.
Officers saw smoke coming out of the apartment when they arrived and then inside discovered 40-year-old Silvia Vaca Abacay on fire and suffering from multiple stab wounds to her upper body, police said. She died at the apartment.
“Officers did everything they could to save her life,” Maj. Ed O’Carroll said.
Investigators said the fire department was already on the way to the building after receiving alerts about an alarm. Firefighters worked to prevent the flames from spreading to nearby homes.
An officer who tried to help Vaca was treated for smoke inhalation, police said.
