So he had to live under Castro for 40 years. Pretty extreme punishment.
The one who escaped had blown off his hands while making a bomb. He was in a hospital with guards and a wire cage over the windows and 3 stories high.
The program said that someone smuggled in wire cutters and he used them to cut through the cage. They never even hinted at it but my guess is that it was arranged by someone in the police dept.
No way did he use those cutters with no hands and leap 3 stories to his freedom.
Castro probably got her a luxury room.
