Two men connected with an ongoing and violent gang rivalry in Atlanta during the summer of 2007 were convicted of aggravated assault charges stemming from a so-called “ambush attack.”

Marco “White Boy” Moses and Moerise “Mo” Williams were found guilty in Fulton County Superior Court of shooting at three men in the Mechanicsville neighborhood in September 2007.

The retaliatory shooting was part of a heated rivalry between a group known as the Campellton Road crew and the violent 30 Deep Gang and the International Robbing Crew. Authorities say the fighting between the gangs was a leading cause of violence crime in Atlanta, with some referring to it as the "Bloody Summer of 2007," the Fulton County District Attorney's Office said.

Moses, 25, and Williams, 29, were among eight arrested in October 2007, one month after the shooting. The eight men were believed to have been involved in three killings in Atlanta earlier that year.

Moses and Williams were linked to the Campbellton Road Crew, the district attorney’s office said. They were convicted of shooting at three people -- one of whom was hit seven times in the arm. The two others ran off and were not hit, the D.A.’s office said.

The people who were shot at are connected with the 30 Deep gang, the district attorney’s office said.

Moses and Williams were convicted on three counts of aggravated assault and weapons charges. A third man, Prentice McNeil, pleaded guilty and was sentenced to 10 years in prison.

McNeil, who also was one of the eight arrested in October 2007, already is in jail having been convicted of murder, aggravated assault and weapons charges for a shooting death that happened six days before the Mechanicsville incident.

The D.A.’s office said the majority of the members of those gangs have been arrested and prosecuted, and there has been no other signs of violence between them.

Moses and Williams will be sentenced at a later date.
