Hundreds Missing From Florida Alligator Alcatraz Detention Center A chilling new report reveals that nearly two-thirds of the 1,800 men taken to the recently built Alligator Alcatraz immigration detention center in July are now missing from official Immigration and Customs Enforcement records. The Miami Herald found that hundreds of detainees have simply vanished from databases, with around 800 men showing no federal record and over 450 listed with only vague instructions to ‘Call ICE for details.’ Many advocates blame poor record-keeping and questionable deportations, including people returned to their home countries by mistake or due to harsh conditions. The situation remains troubling as the facility’s operations continue.
