This is enforced disappearance.

The Trump administration’s Immigration and Customs Enforcement (ICE) had 288 Venezuelan and Salvadoran migrants in its custody. A vast majority, we now know, were not accused of committing crimes, and only a handful faced allegations of committing violent crimes (see CBS News, Bloomberg, the New York Times, and Cristosal).

Then, they disappeared from ICE’s locator system and have apparently ended up in El Salvador’s Center for the Confinement of Terrorism (CECOT) prison. But nothing is certain because neither the U.S. nor the Salvadoran governments has confirmed their names. What we know about these individuals’ identities is entirely from leaks to secondary sources. Even their loved ones have no official information, with the partial exception of Kilmar Abrego Garcia—and that is because a judge ordered it.

Disappearing from custody without any official acknowledgment of one’s identity, then being sent to a prison with no end date and no judicial process at all? That, right there, is the definition of enforced disappearance: a major, serious human rights violation that is tragically familiar in Latin America but rare—until now—in the United States.

Here is what we know about the people disappeared from the United States and apparently rendered to incommunicado prison in El Salvador:

Venezuela, 252 people. 137 rendered under the Alien Enemies Act, the rest with final removal orders:

• 238 people rendered to El Salvador on March 15. Names leaked to CBS News on March 20.
• 7 people rendered to El Salvador on March 30. Names leaked to Fox News on March 31.
• 7 people rendered to El Salvador as part of a group of 10 on April 13. Names are unknown. We only know it was 7 people because El Salvador’s president, Nayib Bukele, tweeted on April 20 that 252 Venezuelans are in Salvadoran custody, and 245 Venezuelans were already in El Salvador.

El Salvador, 31 people, all with final removal orders:

• 23 people rendered to El Salvador on March 15. From much reporting, we know the identities of 3: Kilmar Abrego Garcia and credibly alleged MS-13 members César Humberto López Larios alias “Greñas” and César Eliseo Sorto Amaya. The other 20 remain unnamed.
• 10 people rendered to El Salvador on March 30. Names leaked to Fox News on March 31.
• 3 people rendered to El Salvador as part of a group of 10 on April 13. Names are unknown. We only know it was 3 people because El Salvador’s president, Nayib Bukele, tweeted on April 20 that 252 Venezuelans are in Salvadoran custody. As 245 Venezuelans were already in El Salvador, that would mean that 7 of the 10 were Venezuelan, leaving 3 Salvadorans.
