Out of 1,800 immigrants held at “Alligator Alcatraz” in July, over 1,200 have disappeared from ICE’s public system. Nearly two-thirds unaccounted for

Multiple credible news outlets and advocacy reports from September 2025 confirm that a significant number of immigrants detained at the Florida facility known as 'Alligator Alcatraz' have vanished from publicly accessible ICE databases. The Miami Herald, cited by Democracy Now!democracynow.orgdemocracynow.orgMiami Herald: Two-Thirds of Immigrants Held at “Alligator Alcatraz” in July Have..., reports that about two-thirds of the roughly 1,800 detainees held in July are no longer traceable through ICE’s public system. This figure aligns with other sources including EL PAÍS, Irish Legal News, and Latin Times, which describe the disappearance as a serious concern involving hundreds of detainees. Family members and lawyers have reported difficulties locating these individuals, suggesting they are not simply released or deported but rather missing from official tracking.irishlegal.comirishlegal.comUS: Hundreds of detainees vanish from Florida’s ‘Alligator Alcatraz’+2 more

However, the exact reasons for this disappearance are not fully clarified in the sources. Some reports mention possible administrative errors, transfers to undisclosed locations, or systemic issues within ICE’s record-keeping. There is no definitive public evidence that all these individuals have been released or deported, nor confirmation of their current status. Advocacy groups and legal representatives have called for transparency and accountability regarding these disappearances.

In summary, while the core fact that a large majority of detainees are unaccounted for in ICE’s public system is well-supported, the claim does not provide full context on why or how this happened, which remains under investigation.
