Immigrant rights activists in Florida are expressing alarm as they have found themselves “unable to locate” more than 1,000 detainees who have been “administratively disappeared” from the state’s immigrant internment camp known as ”Alligator Alcatraz.”

Detainees and other witnesses, including several members of Congress who visited in July, have described the conditions inside Alligator Alcatraz as horrific. The ramshackle tent camp was set up in a matter of days this summer in the Everglades to warehouse thousands of people detained by ICE, often without criminal charges or warrants, and with restricted access to attorneys.

“Since this depraved torture camp funded with state FEMA funds reopened,” said Tessa Petit, FLIC’s executive director, “we have been unable to locate the fathers, brothers, friends, and sons that are caged there without due process in the ICE locator. Hospitalizations for severe medical incidents, which include cardiac incidents and surgeries, go unreported.”

Thomas Kennedy, a policy analyst at FLIC, said: “What we’re seeing at Alligator Alcatraz is basically a new model of immigration detention, where a state-run facility is operating as an extrajudicial black site, completely outside of the previous models of immigration detention in this country. It’s making what was already a terrible system somehow even worse.”
