Demario James Atwater, 21, charged with first-degree murder
Demario James Atwater, 21 (pictured right), was arrested early Wednesday at a residence in Durham, North Carolina.
Authorities were watching the home after receiving a tip that Atwater was inside. He was charged with first-degree murder in Carson's death. Atwater is believed to be the man in a convenience-store photograph released by police.
A second suspect, Lawrence Alvin Lovett Jr., 17, is being sought in Carson's death, police said. He also faces a first-degree murder charge. Lovett could be armed and dangerous, police told CNN affiliate WRAL.
Police believe Lovett was the man seen in a surveillance-camera photo possibly using Carson's card at an ATM, Chapel Hill Police Chief Brian Curran said.
The pictures showed a young man wearing a hooded sweatshirt and baseball cap. There also appeared to be a large, shadowy form of another person in the back seat of the vehicle, which may have been Carson's SUV.
