A Salvadoran national who fled Texas rather than serve a sentence for sexual assault was returned to the United States Friday, marking the first extradition from El Salvador, the Justice Department said.

The defendant, Jose Marvin Martinez, was convicted in March 2006 in Brazoria County, Texas, on two sex charges, including sexual assault on a child. Martinez, who was free on bond during the trial, was sentenced to eight years in prison and 10 years of community supervision, Justice officials said. But before the jury deliberated his case, Martinez fled.
