Eight felony charges are filed, according to Fairfax’s major crimes unit commander, Major Ed O’Carroll. The suspects every face two counts of second-degree murder and two counts of using a firearm in commission of a felony.

He said authorities received a suggestion Thursday about the whereabouts of a vehicle connected to the situation following a local resident called in. At that moment, they stated they took an undercover individual of attention .

“Thanks to this community, we got our offenders,” O’Carroll said.

He also imputed U.S. Marshals for helping in the arrests.

Police said there was a burglary call at the same home earlier in the week and that they believed the incidents were connected, police said.
