Detectives have charged Cedric Theodis Hobbs Jr., 29, and Alexis Mattocks, 20, in the death of 19-year-old Kyle Harris.
Hobbs and Mattocks are accused of walking into the Cumberland Pawn Shop at 713 Grove Street around 5:15 p.m. Saturday and killing Harris before stealing his car.
"They went into pawn some items, they weren't very happy with the price," Fayetteville Police Spokesperson Dan Grubb said earlier this week. "They refused to sell, then came back in the store and robbed the place. As the victim was turned around facing the other way he was shot."
Investigators say during the holdup, the suspects got the keys to Harris' car. The pair were captured in Washington DC early Sunday morning - still driving Harris' Saturn Ion.
Hobbs and Mattocks are charged with first-degree murder, second-degree kidnapping, robbery with a dangerous weapon, and conspiracy to commit armed robbery.
On Friday afternoon, the couple arrived at the Cumberland County Jail.
Both suspects are also wanted for questioning in a suspicious death that occurred in McDuffie County, Georgia earlier Saturday, and police say Hobbs has a history of armed robberies and assaults on law enforcement officials.
Late Monday afternoon Fayetteville police confirmed Hobbs confessed, to the Fayetteville shooting, and one shooting in Georgia, but authorities say his alleged accomplice isn't talking.
Police say the couple's 9-month-old child is in DSS custody in Washington.
Harris was a 2009 graduate of Cape Fear High School who was in college at UNC Greensboro. He was a sophomore majoring in sociology. Friends and family tell ABC11 he traveled back home on weekends to work at the pawnshop.
