Police said 17-year-old Levianthan "Levi" Henry Norwood was detained for shoplifting at a Durham Target. He gave police a fake name but after some investigation, they were able to determine his identity.
He is currently in custody in Durham and will face a judge to determine the next steps and the extradition process.
Police said Levi 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. The vehicle was located near the Target where Levi was found, but the gun has not yet been recovered.
