Police said 17-year-old Levianthan "Levi" Henry Norwood was on the run after his mother, 34-year-old Jennifer Norwood, and his 6-year-old brother, Wyatt Norwood, were both fatally shot Friday at their home in Midland, about 50 miles southwest of Washington, D.C.
The father, 37-year-old Joshua Norwood, was also shot but is in stable condition.
Levi Norwood allegedly fled the scene in a stolen red 2007 Toyota Camry.
According to the Fauquier County Sheriff's Office, Norwood was apprehended in North Carolina on Saturday afternoon after store employees called in a shoplifter to police.
The Toyota Camry was also recovered during the arrest, investigators said.
