The pair accused of killing Clark Atlanta University student Alexis Crawford pleaded not guilty to the crime, the Fulton County District Attorney's Office said Tuesday.

Jordyn Jones, 22, and her boyfriend, Barron Brantley, 21, are charged with murder in the Oct. 31 death of Crawford. Crawford, 21, was a Clark Atlanta senior and lived with Jones in an off-campus apartment.

Late last month, a Fulton grand jury indicted both Jones and Brantley on numerous charges, including two counts of felony murder and one count each of murder, aggravated assault, false imprisonment and concealing the death of another. Brantley also was indicted on one count of aggravated sodomy. He is accused of sexually assaulting Crawford five days before her death, according to the DA’s office.

On Monday, Jones and Brantley waived their arraignment hearings, when their charges were formally read. Both pleaded not guilty, the DA’s office said. Both Jones and Brantley are being held without bond at the Fulton jail.

Crawford’s family reported her missing on Nov. 1, launching a week-long search to find the Athens native. Investigators now believe Crawford was dead before she was reported missing.

On Nov. 8, Brantley admitted to investigators that he had choked and killed her, according to court documents. Crawford’s body was found the same day at a DeKalb County park, Atlanta police said. Brantley and Jones were both arrested and charged with Crawford’s murder.

Last week, the DA's office said prosecutors will not seek the death penalty for Brantley and Jones if the two are convicted.

Atlanta police believe an alleged rape is the main motive behind her killing.
