GWINNETT COUNTY, GA — A Lawrenceville man has sentenced to life in prison with the possibility of parole after being convicted of killing a teenager during a gun sale that was set up through social media.

Gwinnett County prosecutors say 19-year-old Miguel Gabriel Flores is accused of plotting to rob 16-year-old Abel Castellanos after responding to his online ad.

During the gun exchange, Castellanos was shot and killed.

Other suspects charged in the case will face trial at a later date, officials say.
