During the trial, federal prosecutors described how Brown recruited an underage girl in 2005 and used vicious physical and sexual assaults to keep the victim under his control until September 2009. In one attack, Brown inflicted severe injuries and poured bleach in the victim’s wounds.

Brown forced another underage girl into prostitution into September 2009 for about two weeks, until she escaped after severe beatings and sexual assaults.

Judge Frank C. Damrell said Brown’s actions “violated the laws of humanity” and inflicted “inhuman” suffering on his victims.

“They were little girls,” Judge Damrell said. “You degraded them to the point of being animals.”
