Three South Fulton teenagers will spend years behind bars for robbing and assaulting two pizza delivery drivers during a 2017 crime spree, authorities said.

Tyyneefah Wells, 18, De’Quandre Weaver, 16, and Anthony Cleveland, 15, pleaded guilty Tuesday, the Fulton County District Attorney’s Office said in a news release.

The teens, who were 13, 14 and 16 years old at the time of the robberies, were tried as adults.

Authorities said the trio called Marco’s Pizza on July 6, 2017, and had the driver bring the delivery to an abandoned home on Smoke Ridge Drive. When the 20-year-old driver arrived, he was attacked and shot three times, police said.

Despite being critically injured, the driver managed to get away.

The next day, the teens struck again, this time calling a Papa John’s location. A delivery driver told police when she arrived to drop the food off at a home on Buckhurst Trail, she had a gun pressed to the back of her head.

Wells, Weaver and Cleveland then punched the woman in the face before stealing her wallet and driving off in her car, authorities said.

They were later arrested after police spotted the stolen vehicle. Investigators determined that all three teens were members of a prominent Atlanta gang.

In court, prosecutors played cellphone video of Weaver bragging about the shooting and robbery shortly after it happened. In the footage, the teen can be seen waving a handgun around.

Weaver was sentenced to 20 years after pleading guilty to armed robbery, hijacking a motor vehicle, aggravated assault with a deadly weapon, aggravated assault with intent to murder, participation in criminal street gang activity, possession of a firearm during the commission of a felony and simple battery.

Wells was given a 15-year-sentence with eight to serve in custody after pleading guilty to robbery, aggravated assault with a deadly weapon, aggravated assault with intent to murder, participation in criminal street gang activity, possession of a firearm during the commission of a felony and battery.

Cleveland must serve four years of his 15-year sentence after pleading guilty to charges of robbery, aggravated assault with a deadly weapon, participation in criminal street gang activity, possession of a firearm during the commission of a felony and battery.
