Religious leaders, advocates and family members of detainees gathered for a vigil outside Alligator Alcatraz. Officials deny their claims.

Alligator Alcatraz came to life in June after Florida's attorney general announced on social media that a detention center would be built in Collier.

Construction of “Alligator Alcatraz” could be halted indefinitely as a federal judge considered whether the development on wetlands violates environmental laws.
