It initially appeared that 23-year-old Helen Hargan may have murdered her 63-year-old mother, Pamela Hargan, before she killed herself, but police announced on Nov. 9 that Helen’s sister, 35-year-old Megan Hargan, was charged in both deaths.
“We have arrested 35-year-old Megan Hargan for the murders of her sister Helen Hargan and mother Pamela Hargan in 2017,” wrote police in Fairfax County, Virginia.
