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.

Wilbert Castañeda suffered traumatic brain injuries in the Navy, which “led him to make a bad decision” to go to Venezuela, his brother said.

A group of 10 Americans freed in a hostage exchange with Venezuela included a U.S. Navy sailor and a water sports fan, reports say. When contacted for comment, the U.S. State Department told Newsweek on Saturday that for privacy reasons, the individuals would not be identified nor their cases disclosed.

As inflation surges under President Trump’s renewed sanctions, Venezuelan authorities are trying to keep a lid on the country’s worsening financial situation.

Forty-eight Venezuelans detained by their own government have so far been released under the terms of a prisoner exchange agreed with the United States, legal rights advocacy group Foro Penal said on Monday.

Venezuela Attorney General Tarek Saab said on Monday that his office will investigate El Salvador's President Nayib Bukele and two other officials for the alleged abuse of Venezuelans who were detained in the Central American country.
