The Justice Department is investigating whether to prosecute two white Pennsylvania teenagers on civil rights statutes for their role in the fatal beating of Luis Ramirez, a Mexican immigrant in the town of Shenandoah. On Friday, an all-white jury exonerated the two teenagers of the most serious charges in connection with the fatal beating. The Mexican American Legal Defense and Education Fund condemned the jury’s finding. Witnesses said six teenagers brutally beat Luis Ramirez last year while yelling racial slurs. When a friend of Ramirez tried to stop the beating, one of the teenagers said, “Tell your Mexican friends to get out of town, or you’ll be laying next to him.”
