Defendant Develle Johnson also was convicted Thursday of employment of a firearm in the commission of a dangerous felony. He will be sentenced next month by Judge Glenn Wright.
The incident occurred on Aug. 31, 2014, in the Camelot Manor Apartments in southeast Memphis where Johnson went to meet another man who had advertised online a Sony PlayStation 4.
During the meeting, an argument developed over the sale price and Johnson pulled a gun and began firing, striking the victim nine times in the chest and abdomen. The 25-year-old victim managed to pull his own gun and shot Johnson once in the chest.
One other defendant is awaiting trial, while a third was never identified.
The case was handled by Asst. Dist. Atty. Muriel Malone.
