MARIETTA, Ga. (AP) — A Georgia man who killed a college student answering an ad on Craigslist has been convicted of murder and faces life in prison.

Cobb County District Attorney Vic Reynolds says 24-year-old Kalynn Shiquez Ruthenberg was found guilty late Tuesday in the 2015 shooting death of 21-year-old James E. Jones.

Reynolds says Jones was a junior at Clark Atlanta University when he responded Feb. 9, 2015, to a Craigslist post advertising an iPhone for sale. Ruthenberg and two other men shot him with a .45-caliber gun when he arrived, and then stole his cellphone. As Jones lay dying, Reynolds says Ruthenberg told one of the other men to take Jones’ Nike tennis shoes and then shot him again.

Sentencing is set for Nov. 20.
