Al Megrahi, who has terminal prostate cancer, is mid-way through a second appeal against his conviction. He was sentenced to a minimum of 27 years in 2001. A fellow defendant was found not guilty. The bomb killed 259 people on board the plane and 11 on the ground. Susan Cohen, whose only child, Theodora, 20, was one of 35 Syracuse University students to lose their lives, said: "Any letting out of Megrahi would be a disgrace. It makes me sick, and if there is a compassionate release then I think that is vile."
