Dahud Hanid Ortiz, a former U.S. Marine convicted of a triple homicide in Spain, was among 10 Americans repatriated in exchange for 250 Venezuelans held in El Salvador.

The Trump administration said it was protecting Americans unjustly held abroad. One of the rescued men, Dahud Hanid Ortiz, killed three people, according to court documents.

But one of those men is an American-Venezuelan dual citizen who was convicted of murdering three people in Spain in 2016, according to Venezuelan court records and statements from officials in Madrid.
