Megan Hargan, 35, was taken into custody in West Virginia, Fairfax County police said in a tweet Friday morning. Authorities are expected to provide more details about the arrest at a 1:30 p.m. news conference. WTOP will have a reporter at the news conference.
The bodies of Helen Hargan, 23, and Pamela Hansen Hargan, 63, were found shot to death inside their McLean house in July 2017. Police had initially said it appeared Helen Hargen shot her mother and then turned the gun on herself.
However, police documents filed last November indicated they believed the crime scene “may have been altered and staged” to look like a murder-suicide. Suspicion fell on Megan Hargan after she attempted to make “fraudulent” wire transfers from her mother’s accounts after her death, according to police search warrants.
