On Friday, a Gwinnett County jury convicted Brandon L. Mosley, 20, of murder for shooting and killing a teenager during a drug deal at an apartment complex in June 2011, according to an AJC report.

Angelo Larocca, 19, of Loganville, was found in a stairwell at the Columns at Paxton Apartments in Lilburn by a courtesy officer doing routine off-duty patrols.

Another man, Hunter Mason Davis, also was charged in the death of Larocca. He surrendered, and is accused of arranging a drug transaction and being present during the shooting.

Mosley, of Lilburn, was found guilty of murder, felony murder, armed robbery, aggravated assault, and two counts of possession of a firearm during the commission of a crime, according to the AJC report.
