Since this corrections center opened in 1990, Lisa says that only four residents have been allowed to leave unconditionally. Sixteen other people have left the island, but they're still under supervision.

"This is a very controversial program because all of these people have already served their sentence," Lisa says. "So in a sense, they're being sent to this island to prevent them from crimes that they may commit."
