A Hall County grand jury has indicted two men in an Aug. 9 gang-related shooting that killed one teen and injured three others.

Robert Jacob "Soldier" Montez, 18, and Miguel Guerra "Smiley" Garcia, 18, both of Gainesville, face multiple charges of murder, aggravated assault and gang activity in a 27-count indictment returned this week in Hall County Superior Court.

The indictment accuses Montez, the suspected gunman, of fatally shooting 16-year-old Juan Gomez with a stolen 9 mm handgun. Nagan Le, Pedro Fernando Salcedo and Francisco Amaya also are named as shooting
victims.

Garcia, the suspected driver, is charged as a party to the crimes of murder and aggravated assault.

Authorities believe Montez fired from a Dodge Neon driven by Garcia into a Nissan Sentra containing the victims, who officials say are members of the La Onda 5 street gang.

Montez and Garcia both are members of the SUR-13 gang, authorities said.

The shooting apparently came just after midnight on a Sunday morning when words were exchanged between the two cars outside an East Hall subdivision at the intersection of Harmony Church Road and Thousand Oaks Drive off Gillsville Highway.

Montez, believed to be a leader or "shot-caller" in SUR-13, was indicted on a charge of participation in criminal street gang activity. The indictment alleges that Montez committed murder and aggravated assault "with the intent to maintain and increase his status and position in the criminal street gang SUR-13."

Montez is also charged with terroristic threats for allegedly threatening to kill a Gainesville-Hall County Gang Task Force investigator the day of the shooting.

A third person who authorities say was in the car with Montez and Garcia was also arrested in connection with the shooting but has not been indicted. Jesus Martinez, 17, was charged with aggravated assault.
