A Gwinnett County man could face two life sentences after a jury found him guilty of sex trafficking two teenage girls.

Quantavious Lee Jackson was convicted of four counts of trafficking a person for sexual servitude Thursday afternoon, according to a release from the Gwinnett District Attorney's Office. The case is thought to be the county's first sex trafficking case.

Jackson prostituted and physically abused a 16-year-old girl and a 15-year-old female runaway in various hotels in College Park, Buckhead and Gwinnett County.

Police found the girls in November 2014 in Jackson’s room at the Jameson Inn on Pleasant Hill Road in Duluth, according to the release. Jackson had multiple prostitution ads posted on Backpage.

The girls told jurors Jackson sexually and physically abused them for several days, going as far as beating them and refusing to feed them, according to the release. Jackson also pulled one girl’s hair out and burned the other with a cigarette.

One of the girls cried on the stand as she described Jackson raping her at a Chamblee hotel when she was 15, according to the release. Jackson kept the money from prostitution.

The girls may not be Jackson’s only victims, according to the release. He also had multiple girls in hotel rooms in Atlanta.

Jackson will be sentenced the week of June 27.
